21 | Environment | A JSON dictionary | Optional|Depends on VNF action.|
22 | | representing a Chef | | |
23 | | Environment object. If | | |
24 | | the VNF action requires | | |
25 | | loading or modifying Chef| | |
26 | | environment attributes | | |
27 | | associated with the VNF, | | |
28 | | all the relevant | | |
29 | | information must be | | |

39 | | The Node JSON dictionary | | |
40 | | must include the run list| | |
41 | | to be triggered for the | | |
42 | | desired VNF action by the| | |
43 | | push job. It should also | | |
44 | | include any attributes | | |
45 | | that need to be | | |
46 | | configured on the Node | | |
47 | | Object as part of the VNF| | |
49 +----------------+--------------------------+---------+----------------------+
50 | NodeList | Array of FQDNs that |Mandatory| |
51 | | correspond to the | | |
52 | | endpoints (VMs) of a VNF | | |
53 | | registered with the Chef | | |
54 | | Server that need to | | |
55 | | trigger a chef-client run| | |
56 | | as part of the desired | | |
58 +----------------+--------------------------+---------+----------------------+
59 | PushJobFlag | This field indicates |Mandatory| If set to “True”, |
60 | | whether the VNF action | | ONAP will request a |
61 | | requires a push Job. Push| | push job. Ignored |
62 | | job object will be | | otherwise. |
63 | | created by ONAP if | | |
65 +----------------+--------------------------+---------+----------------------+
66 | CallbackCapable| This field indicates if | Optional| If Chef cookbook is |
67 | | the chef-client run | | callback capable, VNF|
68 | | invoked by push job | | owner is required to |
69 | | corresponding to the VNF | | set it to “True”. |
70 | | action is capable of | | Ignored otherwise. |
71 | | posting results on a | | |

74 | GetOutputFlag | Flag which indicates |Mandatory| ONAP will retrieve |
75 | | whether ONAP should | | output from |
76 | | retrieve output generated| | NodeObject attributes|
77 | | in a chef-client run from| | [‘PushJobOutput’] for|
78 | | Node object attribute | | all nodes in NodeList|

84 Chef Template example:
90 "description": "VNF Chef environment for HAR",
91 "json\_class": "Chef::Environment",
92 "chef\_type": "environment",
93 "default\_attributes": { },
94 "override\_attributes": {
97 “Database\_IP”:”10.10.1.5”
102 “name” : “signal.network.com “
103 "chef\_type": "node",
104 "json\_class": "Chef::Node",
106 “IPAddress1”: “192.168.1.2”,
107 “IPAddress2”:”135.16.162.5”,
114 “chef\_environment” : “\_default”
115 "run\_list": [ "configure\_signal" ]
117 “NodeList”:[“node1.vnf\_a.onap.com”, “node2.vnf\_a.onap.com”],
118 “PushJobFlag”: “True”
119 “CallbackCapable”:True
120 “GetOutputFlag” : “False”
123 The example JSON file provided by the VNF provider for each VNF action will be
124 turned into a template by ONAP, that can be updated with instance
125 specific values at run-time.
127 Some points worth noting regarding the JSON fields:
129 a. The JSON file must be created for each action for each VNF.
131 b. If a VNF action involves multiple endpoints (VMs) of a VNF, ONAP will
132 replicate the “Node” JSON dictionary in the template and post it to
133 each FQDN (i.e., endpoint) in the NodeList after setting the “name”
134 field in the Node object to be the respective FQDN [1]_. Hence, it
135 is required that all end points (VMs) of a VNF involved in a VNF
136 action support the same set of Node Object attributes.
138 The following table describes the JSON dictionary to post in Callback.

226 +---------------+----------------------+---------+----------------------------+
227 | FileParameters| A JSON dictionary | Optional| Depends on the VNF action |
228 | | where keys are | | and playbook design. |
229 | | filenames and values | | |
230 | | are contents of | | |

232 | | Server will utilize | | |
233 | | this feature to | | |
234 | | generate files with | | |
235 | | keys as filenames and| | |
236 | | values as content. | | |
237 | | This attribute can be| | |
238 | | used to generate | | |

269 “FileParameters”:{“config.txt”:”db\_ip=10.1.1.1, sip\_timer=10000”}
273 In the above example, the Ansible Server will:
275 a. Process the “FileParameters” dictionary and generate a file named
276 ‘config.txt’ with contents set to the value of the ‘config.txt’ key.
278 b. Execute the playbook named ‘<VNFCode>/<Version>/ansible/configure/site.yml’
279 on nodes with FQDNs test1.vnf\_b.onap.com and test2.vnf\_b.onap.com
280 respectively while providing the following key value pairs to the playbook:
281 Retry=3, Wait=5, ConfigFile=config.txt
284 c. If execution time of the playbook exceeds 60 secs (across all hosts),
285 it will be terminated.

444 1. Entitlement and License Key Limits
446 Limitations on the use of software entitlements and license keys may be
447 based on factors such as: features enabled in the product, the allowed
448 capacity of the product, number of installations, etc... The limits may
449 generally be categorized as:
461 Multiple limits may be applicable for an entitlement or license key.
462 Each limit may further be described by limit behavior, duration,
463 quantification, aggregation, aggregation interval, start date, end date,
466 When the limit is associated with a quantity, the quantity is relative
467 to an instance of the entitlement or license key. For example:
469 - Each entitlement grants the right to 50 concurrent users. If 10
470 entitlements are purchased, the total number of concurrent users
471 permitted would be 500. In this example, the limit category is
472 **amount**, the limit type is **users**, and the limit
473 **quantification** is **50.**
475 Each license key may be installed on 3 devices. If 5 license keys are
476 acquired, the total number of devices allowed would be 15. In this
477 example, the limit category is **usages**, the limit type is
478 **device**, and the limit **quantification** is **3.**
482 Locations may be logical or physical location (e.g., site, country). For
485 - use is allowed in Canada

886 **VNF Development Requirements**
887 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
892 R-58421 The VNF **SHOULD** be decomposed into granular re-usable VNFCs.
894 R-82223 The VNF **MUST** be decomposed if the functions have
895 significantly different scaling characteristics (e.g., signaling
896 versus media functions, control versus data plane functions).
898 R-16496 The VNF **MUST** enable instantiating only the functionality that
899 is needed for the decomposed VNF (e.g., if transcoding is not needed it
900 should not be instantiated).
902 R-02360 The VNFC **MUST** be designed as a standalone, executable process.
904 R-34484 The VNF **SHOULD** create a single component VNF for VNFCs
905 that can be used by other VNFs.
907 R-23035 The VNF **MUST** be designed to scale horizontally (more
908 instances of a VNF or VNFC) and not vertically (moving the existing
909 instances to larger VMs or increasing the resources within a VM)
910 to achieve effective utilization of cloud resources.
912 R-30650 The VNF **MUST** utilize cloud provided infrastructure and
913 VNFs (e.g., virtualized Local Load Balancer) as part of the VNF so
914 that the cloud can manage and provide a consistent service resiliency
915 and methods across all VNF's.
917 R-12709 The VNFC **SHOULD** be independently deployed, configured,
918 upgraded, scaled, monitored, and administered by ONAP.
920 R-37692 The VNFC **MUST** provide API versioning to allow for
921 independent upgrades of VNFC.
923 R-86585 The VNFC **SHOULD** minimize the use of state within
924 a VNFC to facilitate the movement of traffic from one instance
927 R-65134 The VNF **SHOULD** maintain state in a geographically
928 redundant datastore that may, in fact, be its own VNFC.
930 R-75850 The VNF **SHOULD** decouple persistent data from the VNFC
931 and keep it in its own datastore that can be reached by all instances
932 of the VNFC requiring the data.
934 R-88199 The VNF **MUST** utilize a persistent datastore service that
935 can meet the data performance/latency requirements. (For example:
936 Datastore service could be a VNFC in VNF or a DBaaS in the Cloud
937 execution environment)
939 R-99656 The VNF **MUST** NOT terminate stable sessions if a VNFC
942 R-84473 The VNF **MUST** enable DPDK in the guest OS for VNF’s requiring
943 high packets/sec performance. High packet throughput is defined as greater
944 than 500K packets/sec.
946 R-54430 The VNF **MUST** use the NCSP’s supported library and compute
947 flavor that supports DPDK to optimize network efficiency if using DPDK. [5]_
949 R-18864 The VNF **MUST** NOT use technologies that bypass virtualization
950 layers (such as SR-IOV) unless approved by the NCSP (e.g., if necessary
951 to meet functional or performance requirements).
953 R-64768 The VNF **MUST** limit the size of application data packets
954 to no larger than 9000 bytes for SDN network-based tunneling when
955 guest data packets are transported between tunnel endpoints that
956 support guest logical networks.
958 R-74481 The VNF **MUST** NOT require the use of a dynamic routing
959 protocol unless necessary to meet functional requirements.
962 ~~~~~~~~~~~~~~~~~~~~~~~~~
964 R-52499 The VNF **MUST** meet their own resiliency goals and not rely
965 on the Network Cloud.
967 R-42207 The VNF **MUST** design resiliency into a VNF such that the
968 resiliency deployment model (e.g., active-active) can be chosen at
971 R-03954 The VNF **MUST** survive any single points of failure within
972 the Network Cloud (e.g., virtual NIC, VM, disk failure).
974 R-89010 The VNF **MUST** survive any single points of software failure
975 internal to the VNF (e.g., in memory structures, JMS message queues).
977 R-67709 The VNF **MUST** be designed, built and packaged to enable
978 deployment across multiple fault zones (e.g., VNFCs deployed in
979 different servers, racks, OpenStack regions, geographies) so that
980 in the event of a planned/unplanned downtime of a fault zone, the
981 overall operation/throughput of the VNF is maintained.
983 R-35291 The VNF **MUST** support the ability to failover a VNFC
984 automatically to other geographically redundant sites if not
985 deployed active-active to increase the overall resiliency of the VNF.
987 R-36843 The VNF **MUST** support the ability of the VNFC to be deployable
988 in multi-zoned cloud sites to allow for site support in the event of cloud
989 zone failure or upgrades.
991 R-00098 The VNF **MUST NOT** impact the ability of the VNF to provide
992 service/function due to a single container restart.
994 R-79952 The VNF **SHOULD** support container snapshots if not for rebuild
995 and evacuate for rollback or back out mechanism.
997 R-92935 The VNF **SHOULD** minimize the propagation of state information
998 across multiple data centers to avoid cross data center traffic.
1000 R-26371 The VNF **MUST** detect communication failure for inter VNFC
1001 instance and intra/inter VNF and re-establish communication
1002 automatically to maintain the VNF without manual intervention to
1003 provide service continuity.
1005 R-18725 The VNF **MUST** handle the restart of a single VNFC instance
1006 without requiring all VNFC instances to be restarted.
1008 R-06668 The VNF **MUST** handle the start or restart of VNFC instances
1009 in any order with each VNFC instance establishing or re-establishing
1010 required connections or relationships with other VNFC instances and/or
1011 VNFs required to perform the VNF function/role without requiring VNFC
1012 instance(s) to be started/restarted in a particular order.
1014 R-80070 The VNF **MUST** handle errors and exceptions so that they do
1015 not interrupt processing of incoming VNF requests to maintain service
1016 continuity (where the error is not directly impacting the software
1017 handling the incoming request).
1019 R-32695 The VNF **MUST** provide the ability to modify the number of
1020 retries, the time between retries and the behavior/action taken after
1021 the retries have been exhausted for exception handling to allow the
1022 NCSP to control that behavior, where the interface and/or functional
1023 specification allows for altering behaviour.
1025 R-48356 The VNF **MUST** fully exploit exception handling to the extent
1026 that resources (e.g., threads and memory) are released when no longer
1027 needed regardless of programming language.
1029 R-67918 The VNF **MUST** handle replication race conditions both locally
1030 and geo-located in the event of a data base instance failure to maintain
1033 R-36792 The VNF **MUST** automatically retry/resubmit failed requests
1034 made by the software to its downstream system to increase the success rate.
1036 R-70013 The VNF **MUST NOT** require any manual steps to get it ready for
1037 service after a container rebuild.
1039 R-65515 The VNF **MUST** provide a mechanism and tool to start VNF
1040 containers (VMs) without impacting service or service quality assuming
1041 another VNF in same or other geographical location is processing service
1044 R-94978 The VNF **MUST** provide a mechanism and tool to perform a graceful
1045 shutdown of all the containers (VMs) in the VNF without impacting service
1046 or service quality assuming another VNF in same or other geographical
1047 location can take over traffic and process service requests.
1049 R-22059 The VNF **MUST NOT** execute long running tasks (e.g., IO,
1050 database, network operations, service calls) in a critical section
1051 of code, so as to minimize blocking of other operations and increase
1052 concurrent throughput.
1054 R-63473 The VNF **MUST** automatically advertise newly scaled
1055 components so there is no manual intervention required.
1057 R-74712 The VNF **MUST** utilize FQDNs (and not IP address) for
1058 both Service Chaining and scaling.
1060 R-41159 The VNF **MUST** deliver any and all functionality from any
1061 VNFC in the pool (where pooling is the most suitable solution). The
1062 VNFC pool member should be transparent to the client. Upstream and
1063 downstream clients should only recognize the function being performed,
1064 not the member performing it.
1066 R-85959 The VNF **SHOULD** automatically enable/disable added/removed
1067 sub-components or component so there is no manual intervention required.
1069 R-06885 The VNF **SHOULD** support the ability to scale down a VNFC pool
1070 without jeopardizing active sessions. Ideally, an active session should
1071 not be tied to any particular VNFC instance.
1073 R-12538 The VNF **SHOULD** support load balancing and discovery
1074 mechanisms in resource pools containing VNFC instances.
1076 R-98989 The VNF **SHOULD** utilize resource pooling (threads,
1077 connections, etc.) within the VNF application so that resources
1078 are not being created and destroyed resulting in resource management
1081 R-55345 The VNF **SHOULD** use techniques such as “lazy loading” when
1082 initialization includes loading catalogues and/or lists which can grow
1083 over time, so that the VNF startup time does not grow at a rate
1084 proportional to that of the list.
1086 R-35532 The VNF **SHOULD** release and clear all shared assets (memory,
1087 database operations, connections, locks, etc.) as soon as possible,
1088 especially before long running sync and asynchronous operations, so as
1089 to not prevent use of these assets by other entities.
1091 R-77334 The VNF **MUST** allow configurations and configuration parameters
1092 to be managed under version control to ensure consistent configuration
1093 deployment, traceability and rollback.
1095 R-99766 The VNF **MUST** allow configurations and configuration parameters
1096 to be managed under version control to ensure the ability to rollback to
1097 a known valid configuration.
1099 R-73583 The VNF **MUST** allow changes of configuration parameters
1100 to be consumed by the VNF without requiring the VNF or its sub-components
1101 to be bounced so that the VNF availability is not effected.
1103 R-21558 The VNF **SHOULD** use intelligent routing by having knowledge
1104 of multiple downstream/upstream endpoints that are exposed to it, to
1105 ensure there is no dependency on external services (such as load balancers)
1106 to switch to alternate endpoints.
1108 R-08315 The VNF **SHOULD** use redundant connection pooling to connect
1109 to any backend data source that can be switched between pools in an
1110 automated/scripted fashion to ensure high availability of the connection
1113 R-27995 The VNF **SHOULD** include control loop mechanisms to notify
1114 the consumer of the VNF of their exceeding SLA thresholds so the consumer
1115 is able to control its load against the VNF.
1117 R-73364 The VNF **MUST** support at least two major versions of the
1118 VNF software and/or sub-components to co-exist within production
1119 environments at any time so that upgrades can be applied across
1120 multiple systems in a staggered manner.
1122 R-02454 The VNF **MUST** support the existence of multiple major/minor
1123 versions of the VNF software and/or sub-components and interfaces that
1124 support both forward and backward compatibility to be transparent to
1125 the Service Provider usage.
1127 R-57855 The VNF **MUST** support hitless staggered/rolling deployments
1128 between its redundant instances to allow "soak-time/burn in/slow roll"
1129 which can enable the support of low traffic loads to validate the
1130 deployment prior to supporting full traffic loads.
1132 R-64445 The VNF **MUST** support the ability of a requestor of the
1133 service to determine the version (and therefore capabilities) of the
1134 service so that Network Cloud Service Provider can understand the
1135 capabilities of the service.
1137 R-56793 The VNF **MUST** test for adherence to the defined performance
1138 budgets at each layer, during each delivery cycle with delivered
1139 results, so that the performance budget is measured and the code
1140 is adjusted to meet performance budget.
1142 R-77667 The VNF **MUST** test for adherence to the defined performance
1143 budget at each layer, during each delivery cycle so that the performance
1144 budget is measured and feedback is provided where the performance budget
1147 R-49308 The VNF **SHOULD** test for adherence to the defined resiliency
1148 rating recommendation at each layer, during each delivery cycle with
1149 delivered results, so that the resiliency rating is measured and the
1150 code is adjusted to meet software resiliency requirements.
1152 R-16039 The VNF **SHOULD** test for adherence to the defined
1153 resiliency rating recommendation at each layer, during each

3188 replacing, creating, or deleting new config elements.
3190 R-60106 The xNF **MUST** implement the protocol operation:
3191 **get(filter)** - Retrieve (a filtered subset of) the running
3192 configuration and device state information. This should include
3193 the list of xNF supported schemas.
3195 R-29488 The xNF **MUST** implement the protocol operation:
3196 **get-config(source, filter)** - Retrieve a (filtered subset of
3197 a) configuration from the configuration datastore source.
3199 R-11235 The xNF **MUST** implement the protocol operation:
3200 **kill-session(session)** - Force the termination of **session**.
3202 R-02597 The xNF **MUST** implement the protocol operation:
3203 **lock(target)** - Lock the configuration datastore target.
3205 R-96554 The xNF **MUST** implement the protocol operation:
3206 **unlock(target)** - Unlock the configuration datastore target.
3208 R-29324 The xNF **SHOULD** implement the protocol operation:
3209 **copy-config(target, source) -** Copy the content of the
3210 configuration datastore source to the configuration datastore target.
3212 R-88031 The xNF **SHOULD** implement the protocol operation:
3213 **delete-config(target) -** Delete the named configuration
3216 R-97529 The xNF **SHOULD** implement the protocol operation:
3217 **get-schema(identifier, version, format) -** Retrieve the YANG schema.
3219 R-62468 The xNF **MUST** allow all configuration data to be
3220 edited through a NETCONF <edit-config> operation. Proprietary
3221 NETCONF RPCs that make configuration changes are not sufficient.
3223 R-01382 The xNF **MUST** allow the entire configuration of the
3224 xNF to be retrieved via NETCONF's <get-config> and <edit-config>,
3225 independently of whether it was configured via NETCONF or other
3228 R-28756 The xNF **MUST** support **:partial-lock** and
3229 **:partial-unlock** capabilities, defined in RFC 5717. This
3230 allows multiple independent clients to each write to a different
3231 part of the <running> configuration at the same time.
3233 R-83873 The xNF **MUST** support **:rollback-on-error** value for
3234 the <error-option> parameter to the <edit-config> operation. If any
3235 error occurs during the requested edit operation, then the target
3236 database (usually the running configuration) will be left unaffected.
3237 This provides an 'all-or-nothing' edit mode for a single <edit-config>
3240 R-68990 The xNF **MUST** support the **:startup** capability. It
3241 will allow the running configuration to be copied to this special
3242 database. It can also be locked and unlocked.
3244 R-68200 The xNF **MUST** support the **:url** value to specify
3245 protocol operation source and target parameters. The capability URI
3246 for this feature will indicate which schemes (e.g., file, https, sftp)
3247 that the server supports within a particular URL value. The 'file'
3248 scheme allows for editable local configuration databases. The other
3249 schemes allow for remote storage of configuration databases.
3251 R-20353 The xNF **MUST** implement both **:candidate** and
3252 **:writable-running** capabilities. When both **:candidate** and
3253 **:writable-running** are provided then two locks should be supported.
3255 R-11499 The xNF **MUST** fully support the XPath 1.0 specification
3256 for filtered retrieval of configuration and other database contents.
3257 The 'type' attribute within the <filter> parameter for <get> and
3258 <get-config> operations may be set to 'xpath'. The 'select' attribute
3259 (which contains the XPath expression) will also be supported by the
3260 server. A server may support partial XPath retrieval filtering, but
3261 it cannot advertise the **:xpath** capability unless the entire XPath
3262 1.0 specification is supported.
3264 R-83790 The xNF **MUST** implement the **:validate** capability
3266 R-49145 The xNF **MUST** implement **:confirmed-commit** If
3267 **:candidate** is supported.
3269 R-58358 The xNF **MUST** implement the **:with-defaults** capability
3272 R-59610 The xNF **MUST** implement the data model discovery and
3273 download as defined in [RFC6022].
3275 R-93443 The xNF **MUST** define all data models in YANG [RFC6020],
3276 and the mapping to NETCONF shall follow the rules defined in this RFC.
3278 R-26115 The xNF **MUST** follow the data model upgrade rules defined
3279 in [RFC6020] section 10. All deviations from section 10 rules shall
3280 be handled by a built-in automatic upgrade mechanism.
3282 R-10716 The xNF **MUST** support parallel and simultaneous
3283 configuration of separate objects within itself.
3285 R-29495 The xNF **MUST** support locking if a common object is
3286 being manipulated by two simultaneous NETCONF configuration operations
3287 on the same xNF within the context of the same writable running data
3288 store (e.g., if an interface parameter is being configured then it
3289 should be locked out for configuration by a simultaneous configuration
3290 operation on that same interface parameter).
3292 R-53015 The xNF **MUST** apply locking based on the sequence of
3293 NETCONF operations, with the first configuration operation locking
3294 out all others until completed.
3296 R-02616 The xNF **MUST** permit locking at the finest granularity
3297 if a xNF needs to lock an object for configuration to avoid blocking
3298 simultaneous configuration operations on unrelated objects (e.g., BGP
3299 configuration should not be locked out if an interface is being
3300 configured or entire Interface configuration should not be locked out
3301 if a non-overlapping parameter on the interface is being configured).
3303 R-41829 The xNF **MUST** be able to specify the granularity of the
3304 lock via a restricted or full XPath expression.
3306 R-66793 The xNF **MUST** guarantee the xNF configuration integrity
3307 for all simultaneous configuration operations (e.g., if a change is
3308 attempted to the BUM filter rate from multiple interfaces on the same
3309 EVC, then they need to be sequenced in the xNF without locking either
3310 configuration method out).
3312 R-54190 The xNF **MUST** release locks to prevent permanent lock-outs
3313 when/if a session applying the lock is terminated (e.g., SSH session
3316 R-03465 The xNF **MUST** release locks to prevent permanent lock-outs
3317 when the corresponding <partial-unlock> operation succeeds.
3319 R-63935 The xNF **MUST** release locks to prevent permanent lock-outs
3320 when a user configured timer has expired forcing the NETCONF SSH Session
3321 termination (i.e., product must expose a configuration knob for a user
3322 setting of a lock expiration timer)
3324 R-10173 The xNF **MUST** allow another NETCONF session to be able to
3325 initiate the release of the lock by killing the session owning the lock,
3326 using the <kill-session> operation to guard against hung NETCONF sessions.
3328 R-88899 The xNF **MUST** support simultaneous <commit> operations
3329 within the context of this locking requirements framework.
3331 R-07545 The xNF **MUST** support all operations, administration and
3332 management (OAM) functions available from the supplier for xNFs using
3333 the supplied YANG code and associated NETCONF servers.
3335 R-60656 The xNF **MUST** support sub tree filtering.
3337 R-80898 The xNF **MUST** support heartbeat via a <get> with null filter.
3339 R-25238 The xNF PACKAGE **MUST** validated YANG code using the open
3340 source pyang [3]_ program using the following commands:
3342 R-63953 The xNF **MUST** have the echo command return a zero value
3343 otherwise the validation has failed
3345 R-26508 The xNF **MUST** support a NETCONF server that can be mounted on
3346 OpenDaylight (client) and perform the operations of: modify, update,
3347 change, rollback configurations using each configuration data element,
3348 query each state (non-configuration) data element, execute each YANG
3349 RPC, and receive data through each notification statement.
3351 R-28545 The xNF **MUST** conform its YANG model to RFC 6060,
3352 “YANG - A Data Modeling Language for the Network Configuration
3355 R-22700 The xNF **MUST** conform its YANG model to RFC 6470,
3356 “NETCONF Base Notifications”.
3358 R-10353 The xNF **MUST** conform its YANG model to RFC 6244,
3359 “An Architecture for Network Management Using NETCONF and YANG”.
3361 R-53317 The xNF **MUST** conform its YANG model to RFC 6087,
3362 “Guidelines for Authors and Reviewers of YANG Data Model Documents”.
3364 R-33955 The xNF **SHOULD** conform its YANG model to RFC 6991,
3365 “Common YANG Data Types”.
3367 R-22946 The xNF **SHOULD** conform its YANG model to RFC 6536,
3368 “NETCONF Access Control Model”.
3370 R-10129 The xNF **SHOULD** conform its YANG model to RFC 7223,
3371 “A YANG Data Model for Interface Management”.
3373 R-12271 The xNF **SHOULD** conform its YANG model to RFC 7223,
3374 “IANA Interface Type YANG Module”.
3376 R-49036 The xNF **SHOULD** conform its YANG model to RFC 7277,
3377 “A YANG Data Model for IP Management”.
3379 R-87564 The xNF **SHOULD** conform its YANG model to RFC 7317,
3380 “A YANG Data Model for System Management”.
3382 R-24269 The xNF **SHOULD** conform its YANG model to RFC 7407,
3383 “A YANG Data Model for SNMP Configuration”, if Netconf used to
3384 configure SNMP engine.
3386 R-33946 The xNF **MUST** conform to the NETCONF RFC 4741,
3387 “NETCONF Configuration Protocol”.
3389 R-04158 The xNF **MUST** conform to the NETCONF RFC 4742,
3390 “Using the NETCONF Configuration Protocol over Secure Shell (SSH)”.
3392 R-13800 The xNF **MUST** conform to the NETCONF RFC 5277,
3393 “NETCONF Event Notification”.
3395 R-01334 The xNF **MUST** conform to the NETCONF RFC 5717,
3396 “Partial Lock Remote Procedure Call”.
3398 R-08134 The xNF **MUST** conform to the NETCONF RFC 6241,
3399 “NETCONF Configuration Protocol”.
3401 R-78282 The xNF **MUST** conform to the NETCONF RFC 6242,
3402 “Using the Network Configuration Protocol over Secure Shell”.
3404 R-31809 The xNF **MUST** support the HealthCheck RPC. The HealthCheck
3405 RPC executes a xNF Provider-defined xNF HealthCheck over the scope of
3406 the entire xNF (e.g., if there are multiple VNFCs, then run a health check,
3407 as appropriate, for all VNFCs). It returns a 200 OK if the test completes.
3408 A JSON object is returned indicating state (healthy, unhealthy), scope
3409 identifier, time-stamp and one or more blocks containing info and fault
3410 information. If the xNF is unable to run the HealthCheck, return a
3411 standard http error code and message.
3413 R-79224 The xNF **MUST** have the chef-client be preloaded with
3414 validator keys and configuration to register with the designated
3415 Chef Server as part of the installation process.
3417 R-72184 The xNF **MUST** have routable FQDNs for all the endpoints
3418 (VMs) of a xNF that contain chef-clients which are used to register
3419 with the Chef Server. As part of invoking xNF actions, ONAP will
3420 trigger push jobs against FQDNs of endpoints for a xNF, if required.
3422 R-47068 The xNF **MAY** expose a single endpoint that is
3423 responsible for all functionality.
3425 R-67114 The xNF **MUST** be installed with Chef-Client >= 12.0 and
3426 Chef push jobs client >= 2.0.
3428 R-27310 The xNF Package **MUST** include all relevant Chef artifacts
3429 (roles/cookbooks/recipes) required to execute xNF actions requested by
3430 ONAP for loading on appropriate Chef Server.
3432 R-26567 The xNF Package **MUST** include a run list of
3433 roles/cookbooks/recipes, for each supported xNF action, that will
3434 perform the desired xNF action in its entirety as specified by ONAP
3435 (see Section 7.c, ONAP Controller APIs and Behavior, for list of xNF
3436 actions and requirements), when triggered by a chef-client run list
3439 R-98911 The xNF **MUST NOT** use any instance specific parameters
3440 for the xNF in roles/cookbooks/recipes invoked for a xNF action.
3442 R-37929 The xNF **MUST** accept all necessary instance specific
3443 data from the environment or node object attributes for the xNF
3444 in roles/cookbooks/recipes invoked for a xNF action.
3446 R-62170 The xNF **MUST** over-ride any default values for
3447 configurable parameters that can be set by ONAP in the roles,
3448 cookbooks and recipes.
3450 R-78116 The xNF **MUST** update status on the Chef Server
3451 appropriately (e.g., via a fail or raise an exception) if the
3452 chef-client run encounters any critical errors/failures when
3453 executing a xNF action.
3455 R-44013 The xNF **MUST** populate an attribute, defined as node
3456 [‘PushJobOutput’] with the desired output on all nodes in the push job
3457 that execute chef-client run if the xNF action requires the output of a
3458 chef-client run be made available (e.g., get running configuration).
3460 R-30654 The xNF Package **MUST** have appropriate cookbooks that are
3461 designed to automatically ‘rollback’ to the original state in case of
3462 any errors for actions that change state of the xNF (e.g., configure).
3464 R-65755 The xNF **SHOULD** support callback URLs to return information
3465 to ONAP upon completion of the chef-client run for any chef-client run
3466 associated with a xNF action.
3468 R-15885 The xNF **MUST** Upon completion of the chef-client run,
3469 POST back on the callback URL, a JSON object as described in Table
3470 A2 if the chef-client run list includes a cookbook/recipe that is
3471 callback capable. Failure to POST on the Callback Url should not be
3472 considered a critical error. That is, if the chef-client successfully
3473 completes the xNF action, it should reflect this status on the Chef
3474 Server regardless of whether the Callback succeeded or not.
3476 R-32217 The xNF **MUST** have routable FQDNs that are reachable via
3477 the Ansible Server for the endpoints (VMs) of a xNF on which playbooks
3478 will be executed. ONAP will initiate requests to the Ansible Server
3479 for invocation of playbooks against these end points [4]_.
3481 R-54373 The xNF **MUST** have Python >= 2.6 on the endpoint VM(s)
3482 of a xNF on which an Ansible playbook will be executed.
3484 R-35401 The xNF **MUST** support SSH and allow SSH access by the
3485 Ansible server for the endpoint VM(s) and comply with the Network
3486 Cloud Service Provider guidelines for authentication and access.
3488 R-82018 The xNF **MUST** load the Ansible Server SSH public key onto xNF
3489 VM(s) as part of instantiation. This will allow the Ansible Server
3490 to authenticate to perform post-instantiation configuration without
3491 manual intervention and without requiring specific xNF login IDs
3494 R-92866 The xNF **MUST** include as part of post-instantiation configuration
3495 done by Ansible Playbooks the removal/update of the SSH public key from
3496 /root/.ssh/authorized_keys, and update of SSH keys loaded through
3497 instantiation to support Ansible. This may include download and install of
3498 new SSH keys and new mechanized IDs.
3500 R-91745 The xNF **MUST** update the Ansible Server and other entities
3501 storing and using the SSH keys for authentication when the SSH keys used
3502 by Ansible are regenerated/updated.
3504 R-40293 The xNF **MUST** make available playbooks that conform
3505 to the ONAP requirement.
3507 R-49396 The xNF **MUST** support each ONAP (APPC) xNF action by invocation
3508 of **one** playbook [7]_. The playbook will be responsible
3509 for executing all necessary tasks (as well as calling other playbooks)
3510 to complete the request.
3512 R-33280 The xNF **MUST NOT** use any instance specific parameters
3515 R-48698 The xNF **MUST** utilize information from key value pairs
3516 that will be provided by the Ansible Server as "extra-vars" during
3517 invocation to execute the desired xNF action. If the playbook requires
3518 files, they must also be supplied using the methodology detailed in
3519 the Ansible Server API, unless they are bundled with playbooks, example,
3522 R-43253 The xNF **MUST** use playbooks designed to allow Ansible
3523 Server to infer failure or success based on the “PLAY_RECAP” capability.
3524 NOTE: There are cases where playbooks need to interpret results of a task
3525 and then determine success or failure and return result accordingly
3526 (failure for failed tasks).
3528 R-50252 The xNF **MUST** write to a specific one text files that
3529 will be retrieved and made available by the Ansible Server if, as part
3530 of a xNF action (e.g., audit), a playbook is required to return any
3531 xNF information. The text files must be written in the same directory as
3532 the one from which the playbook is being executed. A text file must be
3533 created for the xNF playbook run targets/affects, with the name
3534 ‘<VNFname>_results.txt’ into which any desired output from each
3535 respective VM/xNF must be written.
3537 R-51442 The xNF **SHOULD** use playbooks that are designed to
3538 automatically ‘rollback’ to the original state in case of any errors
3539 for actions that change state of the xNF (e.g., configure).
3541 R-58301 The xNF **SHOULD NOT** use playbooks that make requests to
3542 Cloud resources e.g. Openstack (nova, neutron, glance, heat, etc.);
3543 therefore, there is no use for Cloud specific variables like Openstack
3544 UUIDs in Ansible Playbooks.
3546 R-02651 The xNF **SHOULD** use the Ansible backup feature to save a
3547 copy of configuration files before implementing changes to support
3548 operations such as backing out of software upgrades, configuration
3549 changes or other work as this will help backing out of configuration
3550 changes when needed.
3552 R-43353 The xNF **MUST** return control from Ansible Playbooks only
3553 after tasks are fully complete, signaling that the playbook completed
3554 all tasks. When starting services, return control only after all services
3555 are up. This is critical for workflows where the next steps are dependent
3557 R-51910 The xNF **MUST** provide all telemetry (e.g., fault event
3558 records, syslog records, performance records etc.) to ONAP using the
3559 model, format and mechanisms described in this section.
3561 R-19624 The xNF **MUST** encode and serialize content delivered to
3562 ONAP using JSON (RFC 7159) plain text format. High-volume data is to
3563 be encoded and serialized using `Avro <http://avro.apache.org/>`_,
3564 where the Avro [6]_ data format are described using JSON.
3568 - JSON plain text format is preferred for moderate volume data sets
3569 (option 1), as JSON has the advantage of having well-understood simple
3570 processing and being human-readable without additional decoding. Examples
3571 of moderate volume data sets include the fault alarms and performance
3572 alerts, heartbeat messages, measurements used for xNF scaling and syslogs.
3573 - Binary format using Avro is preferred for high volume data sets
3574 (option 2) such as mobility flow measurements and other high-volume
3575 streaming events (such as mobility signaling events or SIP signaling)
3576 or bulk data, as this will significantly reduce the volume of data
3577 to be transmitted. As of the date of this document, all events are
3578 reported using plain text JSON and REST.
3579 - Avro content is self-documented, using a JSON schema. The JSON schema is
3580 delivered along with the data content
3581 (http://avro.apache.org/docs/current/ ). This means the presence and
3582 position of data fields can be recognized automatically, as well as the
3583 data format, definition and other attributes. Avro content can be
3584 serialized as JSON tagged text or as binary. In binary format, the
3585 JSON schema is included as a separate data block, so the content is
3586 not tagged, further compressing the volume. For streaming data, Avro
3587 will read the schema when the stream is established and apply the
3588 schema to the received content.
3590 R-98191 The xNF **MUST** vary the frequency that asynchronous data is
3591 delivered based on the content and how data may be aggregated or grouped
3596 - For example, alarms and alerts are expected to be delivered as soon
3597 as they appear. In contrast, other content, such as performance
3598 measurements, KPIs or reported network signaling may have various ways
3599 of packaging and delivering content. Some content should be streamed
3600 immediately; or content may be monitored over a time interval, then packaged
3601 as collection of records and delivered as block; or data may be collected
3602 until a package of a certain size has been collected; or content may be
3603 summarized statistically over a time interval, or computed as a KPI, with
3604 the summary or KPI being delivered.
3605 - We expect the reporting frequency to be configurable depending
3606 on the virtual network function’s needs for management. For example,
3607 Service Provider may choose to vary the frequency of collection between
3608 normal and trouble-shooting scenarios.
3609 - Decisions about the frequency of data reporting will affect the
3610 size of delivered data sets, recommended delivery method, and how the
3611 data will be interpreted by ONAP. These considerations should not
3612 affect deserialization and decoding of the data, which will be guided
3613 by the accompanying JSON schema or GPB definition files.
3615 R-88482 The xNF **SHOULD** use REST using HTTPS delivery of plain
3616 text JSON for moderate sized asynchronous data sets, and for high
3617 volume data sets when feasible.
3619 R-84879 The xNF **MUST** have the capability of maintaining a primary
3620 and backup DNS name (URL) for connecting to ONAP collectors, with the
3621 ability to switch between addresses based on conditions defined by policy
3622 such as time-outs, and buffering to store messages until they can be
3623 delivered. At its discretion, the service provider may choose to populate
3624 only one collector address for a xNF. In this case, the network will
3625 promptly resolve connectivity problems caused by a collector or network
3626 failure transparently to the xNF.
3628 R-81777 The xNF **MUST** be configured with initial address(es) to use
3629 at deployment time. Subsequently, address(es) may be changed through
3630 ONAP-defined policies delivered from ONAP to the xNF using PUTs to a
3631 RESTful API, in the same manner that other controls over data reporting
3632 will be controlled by policy.
3634 R-08312 The xNF **MAY** use another option which is expected to include REST
3635 delivery of binary encoded data sets.
3637 R-79412 The xNF **MAY** use another option which is expected to include TCP
3638 for high volume streaming asynchronous data sets and for other high volume
3639 data sets. TCP delivery can be used for either JSON or binary encoded data
3642 R-01033 The xNF **MAY** use another option which is expected to include SFTP
3643 for asynchronous bulk files, such as bulk files that contain large volumes of
3644 data collected over a long time interval or data collected across many xNFs.
3645 (Preferred is to reorganize the data into more frequent or more focused data
3646 sets, and deliver these by REST or TCP as appropriate.)
3648 R-63229 The xNF **MAY** use another option which is expected to include REST
3649 for synchronous data, using RESTCONF (e.g., for xNF state polling).
3651 R-03070 The xNF **MUST**, by ONAP Policy, provide the ONAP addresses
3652 as data destinations for each xNF, and may be changed by Policy while
3653 the xNF is in operation. We expect the xNF to be capable of redirecting
3654 traffic to changed destinations with no loss of data, for example from
3655 one REST URL to another, or from one TCP host and port to another.
3657 R-06924 The xNF **MUST** deliver asynchronous data as data becomes
3658 available, or according to the configured frequency.
3660 R-73285 The xNF **MUST** must encode, address and deliver the data
3661 as described in the previous paragraphs.
3663 R-42140 The xNF **MUST** respond to data requests from ONAP as soon
3664 as those requests are received, as a synchronous response.
3666 R-34660 The xNF **MUST** use the RESTCONF/NETCONF framework used by
3667 the ONAP configuration subsystem for synchronous communication.
3669 R-86586 The xNF **MUST** use the YANG configuration models and RESTCONF
3670 [RFC8040] (https://tools.ietf.org/html/rfc8040).
3672 R-11240 The xNF **MUST** respond with content encoded in JSON, as
3673 described in the RESTCONF specification. This way the encoding of a
3674 synchronous communication will be consistent with Avro.
3676 R-70266 The xNF **MUST** respond to an ONAP request to deliver the
3677 current data for any of the record types defined in
3678 Event Records - Data Structure Description by returning the requested
3679 record, populated with the current field values. (Currently the defined
3680 record types include fault fields, mobile flow fields, measurements for
3681 xNF scaling fields, and syslog fields. Other record types will be added
3682 in the future as they become standardized and are made available.)
3684 R-46290 The xNF **MUST** respond to an ONAP request to deliver granular
3685 data on device or subsystem status or performance, referencing the YANG
3686 configuration model for the xNF by returning the requested data elements.
3688 R-43327 The xNF **SHOULD** use `Modeling JSON text with YANG
3689 <https://tools.ietf.org/html/rfc7951>`_, If YANG models need to be
3690 translated to and from JSON[RFC7951]. YANG configuration and content can
3691 be represented via JSON, consistent with Avro, as described in “Encoding
3692 and Serialization” section.
3694 R-42366 The xNF **MUST** support secure connections and transports such as
3695 Transport Layer Security (TLS) protocol
3696 [`RFC5246 <https://tools.ietf.org/html/rfc5246>`_] and should adhere to
3697 the best current practices outlined in
3698 `RFC7525 <https://tools.ietf.org/html/rfc7525>`_.
3700 R-44290 The xNF **MUST** control access to ONAP and to xNFs, and creation
3701 of connections, through secure credentials, log-on and exchange mechanisms.
3703 R-47597 The xNF **MUST** carry data in motion only over secure connections.
3705 R-68165 The xNF **MUST** encrypt any content containing Sensitive Personal
3706 Information (SPI) or certain proprietary data, in addition to applying the
3707 regular procedures for securing access and delivery.
3710 Ansible Playbook Examples
3711 -----------------------------------------------
3713 The following sections contain examples of Ansible playbooks
3714 which follow the guidelines.
3716 Guidelines for Playbooks to properly integrate with APPC
3717 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3719 NOTE: To support concurrent requests to multiple VNF instances of same
3720 or different type, VNF hosts and other files with VNF specific default
3721 values are kept or created in separate directories.
3723 Example of an Ansible command (after pwd) to run playbook again
3724 vfdb9904v VNF instance:
3726 .. code-block:: none
3729 /storage/vfdb/V16.1/ansible/configure
3730 $ ansible-playbook -i ../inventory/vfdb9904vhosts site.yml --extra-vars "vnf_instance=vfdb9904v"
3732 NOTE: To preserve Ansible inventory/group_vars capability, that makes
3733 group_vars contents global variables available to all playbooks, when they
3734 reside in the inventory directory, guidelines are being updated to name the
3735 VNF inventory hosts file as (a flat file) <VNFName>hosts, stored in the
3736 inventory directory, not a subdirectory under inventory. In the above
3737 example: vfdb9904vhosts (removed / VNF name and hosts vfdb9904/vhosts)
3739 Example of corresponding APPC API Call from ONAP – Ansible Server
3742 An example of a curl request simulating a Rest API POST requesting execution
3743 of configure Playbook (using playbook relative path):
3745 .. code-block:: none
3747 curl -u APIUser:APIPassword -H "Content-type:application/json" -X POST
3748 -d '{"Id": "8412", "PlaybookName": "vfdb/V5.x.x/ansible/configure/site.yml",
3749 "Timeout":"600", "EnvParameters": { "vnf_instance": "vfdb9904v" }}'
3750 http://ansible.server.com:5000/Dispatch
3752 Rest API GET request to obtain response/results for prior request
3753 (same Id as POST request above):
3755 .. code-block:: none
3757 curl -u APIUser:APIPassword -H 'Content-type: application/json' -X GET
3758 'http://ansible.server.com:5000/Dispatch/?Id=8412&Type=GetResult'
3762 - An ID number is assigned to each request. This ID number is used to
3763 track request down to completion and provide status to APPC when
3766 - Playbook Name relative path provided in the request as PlaybookName
3768 - Ansible Server Rest API is aware of playbook’s root directory which may
3769 vary from instance to instance or Ansible Server cluster to cluster.
3771 Ansible Playbooks will use the VNF instance name (passed using
3772 --extra-vars "vnf\_instance=vfdb9904v") to identify other default values
3773 to run the playbook(s) against the target VNF instance. Same example as
3776 .. code-block:: none
3778 $ ansible-playbook -i ../inventory/vfdb9904vhosts site.yml --extra-vars "vnf_instance=vfdb9904v"
3780 Each Ansible Server or cluster is assigned its own identification to be used
3781 to authenticate to VNF VMs using Ansible Server or cluster specific set of
3782 SSH keys that may be rotated regularly. Here hosts file, no longer referencing
3783 file with SSH key credentials, to run ansible-playbook listed in this example
3784 above (IP addresses were scrubbed):
3786 .. code-block:: none
3788 $ more ../inventory/vfdb9904v/hosts
3790 localhost ansible_connection=local
3800 NOTE: APPC requests to run Playbooks/Cookbooks are specific to a VNF,
3801 but could be more limited to one VM or one type of VM by the request
3802 parameters. Actions that may impact a site (LCP), a service, or an
3803 entire platform must be orchestrated by MSO in order to execute requests
3804 via APPC which then invoke VNF level playbooks. Playbooks that impact
3805 more than a single VNF are not the current focus of these guidelines.
3807 Since last release of these guidelines, based on recent learnings,
3808 moving VNF Type global variables under inventory/group_vars files, this
3809 way variables and respective values are available to all playbooks without
3810 being explicitly referenced though an include statement. Also creating
3811 templates that are VNF Type specific, but moving away from static files
3812 that are VNF instance specific, working to obtain VNF instance specific
3813 from other sources, inventory database, etc.
3815 And here the scrubbed default arguments for this VNF instance(originated
3816 from previously re-factored playbooks now being phased out):
3818 .. code-block:: none
3820 vnf_instance=vfdb9904v
3822 $ more ../vars/vfdb9904v/default_args.yml
3823 vm_config_oam_vnfc_name: vfdb9904vm001oam001
3824 vm_config_oam_hostname: vfdb9904vm001
3825 vm_config_oam_provider_ip_address: 1xx.2yy.zzz.109
3828 IMPORTANT: The APPC and default file attribute name for
3829 vm\_config\_oam\_vnfc\_name, as an example, is derived from vm\_config
3830 array structure (list) in the CSAR package ENV file, with dots replaced
3833 .. code-block:: none
3837 oam: {vnfc_name: {{ vm_config_oam_vnfc_name }}, hostname: {{
3838 vm_config_oam_hostname }}, provider_ip_address: {{
3839 vm_config_oam_provider_ip_address }
3843 Parameters like VNF names, VNFC names, OA&M IP addresses, after
3844 February, 2018 ONAP release, will be extracted from A&AI by APPC and
3845 then passed down to Ansible Server, as part of APPC request through REST
3846 API. In the meantime, VNF instance specific required values, will
3847 be stored on VNF instance directory, default arguments file and will be
3848 used as defaults. For parameterized playbooks attribute-value pairs
3849 passed down by APPC to Ansible Server always take precedence over
3850 template or VNF instance specific defaults stored in defaults file(s).
3852 .. code-block:: none
3855 /storage/vfdb/latest/ansible
3856 Again, originated from previously re-factored playbooks now being phased out:
3858 $ more vars/vfdb9904v/default_args.yml
3860 vm_config_oam1_vnfc_name: vfdb9904vm001oam001
3861 vm_config_oam1_hostname: vfdb9904vm001
3862 vm_config_oam1_provider_ip_address: 1xx.2yy.zzz.109
3864 vm_config_oam2_vnfc_name: vfdb9904vm002oam001
3865 vm_config_oam2_hostname: vfdb9904vm002
3866 vm_config_oam2_provider_ip_address: 1xx.2yy.zzz.110
3868 vm_config_rdb1_vnfc_name: vfdb9904vm003rdb001
3869 vm_config_rdb1_hostname: vfdb9904vm003
3870 vm_config_rdb1_provider_ip_address: 1xx.2yy.zzz.105
3872 vm_config_rdb2_vnfc_name: vfdb9904vm004rdb001
3873 vm_config_rdb2_hostname: vfdb9904vm004
3874 vm_config_rdb2_provider_ip_address: 1xx.2yy.zzz.106
3876 vm_config_rdb3_vnfc_name: vfdb9904vm005rdb001
3877 vm_config_rdb3_hostname: vfdb9904vm005
3878 vm_config_rdb3_provider_ip_address: 1xx.2yy.zzz.xxx
3880 vm_config_rdb4_vnfc_name: vfdb9904vm006rdb001
3881 vm_config_rdb4_hostname: vfdb9904vm006
3882 vm_config_rdb4_provider_ip_address: 1xx.2yy.zzz.yyy
3884 One of the first tasks on the Ansible Playbooks is to combine the VNF
3885 type generic template, derived from ENV files in CSAR or other files,
3886 with these default values stored on the Ansible Server, together with
3887 the overriding parameters passed down from APPC, to create the VNF
3888 instance specific set of attribute-value pairs to be used for the run, in
3889 INI format. Here is an excerpt from such a file that should look
3890 somewhat similar to ENV files:
3892 .. code-block:: none
3894 $ more tmp/vfdb9904v/all.yml
3896 deployment_prefix: vfdb9904v
3900 template_version: '2014-10-16'
3901 stack_name: vfdb9904v
3903 stackName: vfdb9904v
3907 # logins list contain 'login name', 'login group', 'login password'
3909 .. code-block:: none
3912 - { name: 'm99999', group: 'm99999', password: 'abcdefgha' }
3913 - { name: 'gsuser', group: 'gsuser', password: ' abcdefgha' }
3914 - { name: 'peruser', group: 'peruser', password: ' abcdefgha' }
3915 - { name: 'dbuser', group: 'dbuser', password: ' abcdefgha' }
3917 NOTE: Arguments passed by APPC to Ansible Server to run a playbook take
3918 precedence over any defaults stored in Ansible Server.
3920 Ansible Playbooks – Notes On Artifacts Required to Run Playbooks
3921 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3923 Inventory hosts file: should be VNF instance specific.
3925 Default variables: should be VNF instance specific.
3927 NOTE: Some playbooks may rely on inventory directory contents to target
3928 the collection of VNFs in the Services Platform supported through
3931 Playbooks and paths to referenced files: Playbooks shall not use
3932 absolute paths in include or import entries (variables or playbooks) or
3933 other types of references.
3935 For this to work properly, when running playbooks, the directory where
3936 the main playbook resides shall be the current directory.
3938 Playbook imports, when used, shall use paths relative to the main
3941 Root directory named ansible - Any files provided with playbooks,
3942 included, imported, or referenced by playbooks, shall reside under the ansible
3943 playbooks (root) directory, containing all playbook subdirectories, or
3944 below that ansible root directory, in other subdirectories to support
3945 on-boarding and portability of VNF collection of playbooks and related
3948 Designing for a shared environment, concurrently running playbooks,
3949 targeting multiple VNF instances – inventory hosts file:
3951 To avoid inventory hosts file overwrites or collisions between multiple
3952 concurrently running VNF instance requests, chosen approach is for each
3953 VNF instance hosts file, to be stored under the Ansible Server Playbooks
3954 root directory, under the inventory subdirectory, and under a directory
3955 for each VNF instance, named after the VNF instance, as follows:
3957 ansible/inventory/<VNF\_instance\_name>/hosts
3959 Example of inventory hosts file path, relative to ansible playbooks root
3960 directory (playbooks\_dir): ansible/inventory/vnfx0001v/hosts
3962 **Designing for a shared environment, concurrently running multiple playbooks,
3963 targeting multiple VNF instances – default argument variables for
3964 specific VNF instances:**
3966 Files containing attribute name value pairs (variable name and default
3967 values), referenced/included by playbooks – Files containing VNF
3968 instance specific default values – in a later APPC release, some or all
3969 the default attribute value pairs contained in the defaults file, may be
3970 passed down by APPC, to the Ansible Server, overriding these defaults:
3972 VNF instance specific files
3973 referenced/included by playbooks, containing default values, example,
3974 default\_args.yml, shall be stored under a directory with VNF instance
3979 ansible/vars/<VNF\_instance\_name>/default\_args.yml
3981 Example of include statement:
3983 - include_vars: ../vars/{{ vnf_instance }}/default_args.yml
3985 Again, this was originated from previously re-factored playbooks, now being
3986 phased out, to move away from having to create VNF instance specific files
3987 with VNF instance default variables. Moving to extract these values from
3988 inventory databases and provide them to Ansible Server as part of the APPC
3989 request, but may be used in a transition from having everything stored in the
3990 Ansible Server to APPC extracting and providing VNF instance specific
3991 attribute-value pairs to the Ansible Server as part of the request.
3993 Files containing attribute name value pairs (variable name and default
3994 values), referenced/included by playbooks – created dynamically by
3998 overwrites or collisions of multiple concurrently running VNF instance
3999 requests, files created dynamically by playbooks, based on VNF generic
4000 templates, combined with default values and arguments passed down by
4001 APPC (as part of the request), shall be stored under a directory with
4002 VNF instance name on the path.
4006 tmp/<VNF\_instance\_name>/all.yml
4008 Files containing site specific (Openstack location non-instance
4009 specific) attribute name value pairs, like NTP server and DNS server’s
4010 IP addresses and other parameters, referenced/included by playbooks, not
4011 VNF specific – Could/should be stored under inventory/group_vars directory,
4012 in a subdirectory named after the string used to identify the site (nyc1,
4017 ansible/inventory/group_vars/<Site>
4019 ansible/inventory/group_vars/nyc1
4021 ansible/inventory/group_vars/lax2
4024 \ **Ansible Server Design - Directory Structure**
4026 To help understanding the contents of this section, here are few basic
4029 **VNF type a.k.a VNF Function Code** - Based on current Services
4030 Platform naming convention, each Virtual Network Function is assigned a
4031 4 character string (example vfdb), these are 4 characters in
4032 the VNF instance name, followed by (4) numbers, ending in a "v", but the
4033 naming convention is evolving. VNF instance name in
4034 some cases corresponds to the stack name for the VNF when VNF instance
4035 is built based on a single module, single stack. Example of VNF instance
4036 name: vfdb9904v. All VNF performing this function, running the same
4037 software, coming from the same VNF provider will have the same 4
4038 characters in the VNF instance name, in this example, vfdb.
4040 NOTE: New naming convention includes a prefix indicating geographical
4041 location where VNF is instantiated.
4043 VNF type, determined through these 4 characters, is also known as VNF
4044 Function Code and is assigned by inventory team. All Services Platform
4045 VNF Function Codes can be found in inventory database and/or A&AI as
4046 well as Services Platform Network Design Documents.
4048 Version – As in VNF software version is the release of the software
4049 running on the VNF for which the playbooks were developed. VNF
4050 configuration steps may change from release to release and this
4051 <Version> in the path will allow the Ansible Server to host playbooks
4052 associated with each software release. And run the playbooks that match
4053 the software release running on each VNF instance. APPC initially will
4054 not support playbook versioning only latest playbook is supported or a hard
4055 coded version that later should become a variable to allow multiple
4056 actively in use playbook versions according to VNF release.
4058 Playbook Function - Is a name associated with a life cycle management
4059 task(s) performed by the playbook(s) stored in this directory. It should
4060 clearly identify the type of action(s) performed by the main playbook
4061 and possibly other playbooks stored in this same directory. Ideally,
4062 playbook function would match APPC corresponding command or function that
4063 is performed by the main playbook in this directory. Following Ansible naming
4064 standards main playbook is usually named site.yml. There can be other
4065 playbooks on the same directory that use a subset of the roles used by the
4066 main playbook site.yml. Examples of Playbook Function directory names:
4068 - configure – Contains post-instantiation (bulk) configuration
4071 - healthcheck – Contains VNF health check playbook(s), roles,…
4073 - stop – Contains VNF application stop (stopApplication) playbook(s),
4076 - start – Contains VNF application start (startApplication) playbook(s),
4079 Directory structure to allow hosting multiple version sets of playbooks,
4080 for the same VNF type, to be hosted in the runtime environment on the
4081 Ansible Servers. Generic directory structure:
4083 Ansible Playbooks – Function directory and main playbook:
4085 .. code-block:: none
4087 <VNF type>/<Version>/ansible/<Playbook Function>/site.yml
4089 Example – Post-instantiation (bulk) configuration –APPC Function -
4092 .. code-block:: none
4094 <VNF type>/<Version>/ansible/configure/site.yml
4096 Example – Post-instantiation (bulk) configuration –APPC Function
4097 – Configure – VNF software version 16.1:
4099 .. code-block:: none
4101 vfdb/V16.1/ansible/configure/site.yml
4103 Example – Health-check –APPC Function - HealthCheck:
4105 .. code-block:: none
4107 <VNF type>/<Version>/ansible/healthcheck/site.yml
4109 OR (Function directory name does not need to match APPC function name)
4111 .. code-block:: none
4113 <VNF type>/<Version>/ansible/check/site.yml
4115 Ansible Directories for other artifacts – VNF inventory hosts file -
4118 .. code-block:: none
4120 <VNF type>/<Version>/ansible/inventory/<VNF instance name>hosts
4122 Ansible Directories for other artifacts – VNF instance specific default
4123 arguments – Optional:
4125 .. code-block:: none
4127 <VNF type>/<Version>/ansible/group_vars/<VNF instance name>
4129 NOTE: This requirement is expected to be deprecated all or in part in the
4130 future, for automated actions, once APPC can pass down all VNF specific
4131 arguments for each action. Requirement remains while manual actions are
4132 to be supported. Other automated inventory management mechanisms may be
4133 considered in the future, Ansible supports many automated inventory
4134 management mechanisms/tools/solutions.
4136 Ansible Directories for other artifacts – VNF (special) groups –
4139 .. code-block:: none
4141 <VNF type>/<Version>/ansible/inventory/group_vars/<VNF instance name>
4143 NOTE: Default groups will be created based on VNFC type, 3 characters,
4144 on VNFC name. Example: “oam”, “rdb”, “dbs”, “man”, “iox”, “app”,…
4146 Ansible Directories for other artifacts – VNF (special) other files –
4147 Optional – Example – License file:
4149 .. code-block:: none
4151 <VNF type>/<Version>/ansible/<Other directory(s)>
4153 CAUTION: On referenced files used/required by playbooks.
4155 - To avoid missing files, during on-boarding or uploading of Ansible
4156 Playbooks and related artifacts, all permanent files (not generated
4157 by playbooks as part of execution), required to run any playbook,
4158 shall reside under the ansible root directory or below on other
4161 - Any references to files, on includes or other playbook entries, shall
4164 - This is the ansible (root) directory referenced on this
4165 note (Ansible Server mount point not included):
4167 .. code-block:: none
4169 <VNF type>/<Version>/ansible/
4171 There will be a soft link to the latest set of Ansible Playbooks for
4174 VNF type directories use A&AI inventory VNF function code. Ansible
4175 Playbooks will be stored on a Cinder Volume mounted on the Ansible
4176 Servers as /storage. Example:
4178 /storage/vfdb/latest/ansible – This soft link point to the latest set of
4179 playbooks (or the only set)
4181 /storage/vfdb/V16.1/ansible – Root directory for database VNF Ansible
4182 Playbooks for release 16.1
4184 CAUTION: To support this directory structure as the repository to store
4185 Ansible Playbooks run by APPC, APPC API in the Ansible Server side needs
4186 to be configured to run playbooks from directory, not MySQL database.
4188 Ansible Server HTTP will be configured to support APPC REST API requests
4189 to run playbooks as needed, against specific VNF instances, or specific
4190 VM(s) as specified in the request.
4192 ONAP APPC REST API to Ansible Server is documented separately and can be
4193 found under ONAP (onap.org).
4195 **Ansible Server – On-boarding Ansible Playbooks**
4197 Once playbooks are developed following the guidelines listed in prior
4198 section(s), playbooks need to be on-boarded onto Ansible Server(s). In
4199 the future, they’ll be on-boarded and distributed through ONAP, at least
4200 that is the proposed plan, but for now they need to be uploaded
4201 manually. There is work in progress to use a Git as the playbook
4202 repository to store and track playbooks by version, version control.
4204 These are the basic steps to on-board playbooks manually onto the
4207 1. Upload CSAR, zip, or tar file containing VNF playbooks and related
4210 2. Create full directory (using –p option below) to store Ansible
4211 Playbooks and other artifacts under /storage (or other configured)
4214 a. Includes VNF type using VNF function code 4 characters under
4217 b. Includes VNF “Version” directory as part of the path to store
4218 playbooks for this VNF version.
4220 c. Include generic ansible root directory. Creating full directory
4223 .. code-block:: none
4225 $ mkdir –p /storage/vfdb/V16.1/ansible**/**
4227 3. Make this directory (VNF ansible root directory) current directory
4230 .. code-block:: none
4232 cd /storage/vfdb/V16.1/ansible/
4234 4. Extract Ansible Playbooks and other Ansible artifacts associated with
4235 the playbooks onto the ansible directory. Command depends on the type
4236 of file uploaded, examples would be:
4238 .. code-block:: none
4244 5. Create VNF inventory hosts file with all VMs and
4245 OA&M IP addresses for all VNF instances with known OA&M IP addresses
4246 for respective VMs, example:
4248 .. code-block:: none
4252 $ touch inventory/vfdb9904vhosts
4254 $ cat inventory/vfdb9904vhosts
4257 localhost ansible\_connection=local
4267 6. (Optional, being deprecated) Create directory to hold default
4268 arguments for each VNF instance,
4271 .. code-block:: none
4273 $ mkdir –p vars/vfdb9904v
4274 $ touch vars/vfdb9904v/default\_args.yml
4275 $ cat vars/vfdb9904v/default\_args.yml
4276 vm\_config\_oam1\_vnfc\_name: vfdb9904vm001oam001
4277 vm\_config\_oam1\_hostname: vfdb9904vm001
4278 vm\_config\_oam1\_provider\_ip\_address: 1xx.2yy.zzz.109
4280 vm\_config\_oam2\_vnfc\_name: vfdb9904vm002oam001
4281 vm\_config\_oam2\_hostname: vfdb9904vm002
4282 vm\_config\_oam2\_provider\_ip\_address: 1xx.2yy.zzz.110
4284 vm\_config\_rdb1\_vnfc\_name: vfdb9904vm003rdb001
4285 vm\_config\_rdb1\_hostname: vfdb9904vm003
4286 vm\_config\_rdb1\_provider\_ip\_address: 1xx.2yy.zzz.105
4288 vm\_config\_rdb2\_vnfc\_name: vfdb9904vm004rdb001
4289 vm\_config\_rdb2\_hostname: vfdb9904vm004

4303 7. Perform some basic playbook validation running with “--check” option,
4304 running dummy playbooks or other.
4306 NOTE: Each Ansible Server or cluster of Ansible Server will have its own
4307 credentials to authenticate to VNF VMs. Ansible Server SSH public key(s)
4308 have to be loaded onto VNF VMs during instantiation or other way before
4309 Ansible Server can access VNF VMs and run playbooks. HOT templates used
4310 by heat to instantiate VNFs to be configured by these Ansible Servers running
4311 playbooks shall include the same SSH public key and load them onto VNF VM(s)
4312 as part of instantiation.
4314 Other non-vendor specific playbook tasks need to be incorporated in overall
4315 post-instantiation configuration playbook. Alternative is for company
4316 developed playbooks to be uploaded and executed, after VNF vendor provided
