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

2485 per xNF to be used as needed by services (i.e., not tied to a VM
2486 instance) as the recommended solution. The xNF provider may provide

2615 R-62468 The xNF **MUST** allow all configuration data to be
2616 edited through a NETCONF <edit-config> operation. Proprietary
2617 NETCONF RPCs that make configuration changes are not sufficient.
2619 R-01382 The xNF **MUST** allow the entire configuration of the
2620 xNF to be retrieved via NETCONF's <get-config> and <edit-config>,
2621 independently of whether it was configured via NETCONF or other
2624 R-28756 The xNF **MUST** support **:partial-lock** and
2625 **:partial-unlock** capabilities, defined in RFC 5717. This
2626 allows multiple independent clients to each write to a different
2627 part of the <running> configuration at the same time.
2629 R-83873 The xNF **MUST** support **:rollback-on-error** value for
2630 the <error-option> parameter to the <edit-config> operation. If any
2631 error occurs during the requested edit operation, then the target
2632 database (usually the running configuration) will be left unaffected.
2633 This provides an 'all-or-nothing' edit mode for a single <edit-config>
2636 R-68990 The xNF **MUST** support the **:startup** capability. It
2637 will allow the running configuration to be copied to this special
2638 database. It can also be locked and unlocked.
2640 R-68200 The xNF **MUST** support the **:url** value to specify
2641 protocol operation source and target parameters. The capability URI
2642 for this feature will indicate which schemes (e.g., file, https, sftp)
2643 that the server supports within a particular URL value. The 'file'
2644 scheme allows for editable local configuration databases. The other
2645 schemes allow for remote storage of configuration databases.
2647 R-20353 The xNF **MUST** implement both **:candidate** and
2648 **:writable-running** capabilities. When both **:candidate** and
2649 **:writable-running** are provided then two locks should be supported.
2651 R-11499 The xNF **MUST** fully support the XPath 1.0 specification
2652 for filtered retrieval of configuration and other database contents.
2653 The 'type' attribute within the <filter> parameter for <get> and
2654 <get-config> operations may be set to 'xpath'. The 'select' attribute
2655 (which contains the XPath expression) will also be supported by the
2656 server. A server may support partial XPath retrieval filtering, but
2657 it cannot advertise the **:xpath** capability unless the entire XPath
2658 1.0 specification is supported.
2660 R-83790 The xNF **MUST** implement the **:validate** capability
2662 R-49145 The xNF **MUST** implement **:confirmed-commit** If

2675 and the mapping to NETCONF shall follow the rules defined in this RFC.
2677 R-26115 The xNF **MUST** follow the data model upgrade rules defined
2678 in [RFC6020] section 10. All deviations from section 10 rules shall
2679 be handled by a built-in automatic upgrade mechanism.
2681 R-10716 The xNF **MUST** support parallel and simultaneous
2682 configuration of separate objects within itself.
2684 R-29495 The xNF **MUST** support locking if a common object is
2685 being manipulated by two simultaneous NETCONF configuration operations
2686 on the same xNF within the context of the same writable running data
2687 store (e.g., if an interface parameter is being configured then it
2688 should be locked out for configuration by a simultaneous configuration
2689 operation on that same interface parameter).
2691 R-53015 The xNF **MUST** apply locking based on the sequence of
2692 NETCONF operations, with the first configuration operation locking
2693 out all others until completed.
2695 R-02616 The xNF **MUST** permit locking at the finest granularity
2696 if a xNF needs to lock an object for configuration to avoid blocking
2697 simultaneous configuration operations on unrelated objects (e.g., BGP
2698 configuration should not be locked out if an interface is being
2699 configured or entire Interface configuration should not be locked out
2700 if a non-overlapping parameter on the interface is being configured).
2702 R-41829 The xNF **MUST** be able to specify the granularity of the
2703 lock via a restricted or full XPath expression.
2705 R-66793 The xNF **MUST** guarantee the xNF configuration integrity
2706 for all simultaneous configuration operations (e.g., if a change is
2707 attempted to the BUM filter rate from multiple interfaces on the same
2708 EVC, then they need to be sequenced in the xNF without locking either
2709 configuration method out).
2711 R-54190 The xNF **MUST** release locks to prevent permanent lock-outs
2712 when/if a session applying the lock is terminated (e.g., SSH session
2715 R-03465 The xNF **MUST** release locks to prevent permanent lock-outs
2716 when the corresponding <partial-unlock> operation succeeds.
2718 R-63935 The xNF **MUST** release locks to prevent permanent lock-outs
2719 when a user configured timer has expired forcing the NETCONF SSH Session
2720 termination (i.e., product must expose a configuration knob for a user
2721 setting of a lock expiration timer)
2723 R-10173 The xNF **MUST** allow another NETCONF session to be able to
2724 initiate the release of the lock by killing the session owning the lock,
2725 using the <kill-session> operation to guard against hung NETCONF sessions.
2727 R-88899 The xNF **MUST** support simultaneous <commit> operations
2728 within the context of this locking requirements framework.
2730 R-07545 The xNF **MUST** support all operations, administration and
2731 management (OAM) functions available from the supplier for xNFs using
2732 the supplied YANG code and associated NETCONF servers.

2742 source pyang [3]_ program using the following commands:
2744 R-63953 The xNF **MUST** have the echo command return a zero value
2745 otherwise the validation has failed
2747 R-26508 The xNF **MUST** support a NETCONF server that can be mounted on
2748 OpenDaylight (client) and perform the operations of: modify, update,
2749 change, rollback configurations using each configuration data element,
2750 query each state (non-configuration) data element, execute each YANG
2751 RPC, and receive data through each notification statement.

2782 “A YANG Data Model for IP Management”.
2784 R-87564 The xNF **SHOULD** conform its YANG model to RFC 7317,
2785 “A YANG Data Model for System Management”.
2787 R-24269 The xNF **SHOULD** conform its YANG model to RFC 7407,
2788 “A YANG Data Model for SNMP Configuration”.
2790 R-33946 The xNF **MUST** conform to the NETCONF RFC 4741,
2791 “NETCONF Configuration Protocol”.
2793 R-04158 The xNF **MUST** conform to the NETCONF RFC 4742,
2794 “Using the NETCONF Configuration Protocol over Secure Shell (SSH)”.
2796 R-13800 The xNF **MUST** conform to the NETCONF RFC 5277,
2797 “NETCONF Event Notification”.
2799 R-01334 The xNF **MUST** conform to the NETCONF RFC 5717,
2800 “Partial Lock Remote Procedure Call”.
2802 R-08134 The xNF **MUST** conform to the NETCONF RFC 6241,
2803 “NETCONF Configuration Protocol”.
2805 R-78282 The xNF **MUST** conform to the NETCONF RFC 6242,
2806 “Using the Network Configuration Protocol over Secure Shell”.
2808 R-31809 The xNF **MUST** support the HealthCheck RPC. The HealthCheck
2809 RPC executes a xNF Provider-defined xNF HealthCheck over the scope of
2810 the entire xNF (e.g., if there are multiple VNFCs, then run a health check,
2811 as appropriate, for all VNFCs). It returns a 200 OK if the test completes.
2812 A JSON object is returned indicating state (healthy, unhealthy), scope
2813 identifier, time-stamp and one or more blocks containing info and fault
2814 information. If the xNF is unable to run the HealthCheck, return a
2815 standard http error code and message.
2817 R-79224 The xNF **MUST** have the chef-client be preloaded with
2818 validator keys and configuration to register with the designated
2819 Chef Server as part of the installation process.
2821 R-72184 The xNF **MUST** have routable FQDNs for all the endpoints
2822 (VMs) of a xNF that contain chef-clients which are used to register
2823 with the Chef Server. As part of invoking xNF actions, ONAP will
2824 trigger push jobs against FQDNs of endpoints for a xNF, if required.
2826 R-47068 The xNF **MAY** expose a single endpoint that is
2827 responsible for all functionality.
2829 R-67114 The xNF **MUST** be installed with Chef-Client >= 12.0 and
2830 Chef push jobs client >= 2.0.
2832 R-27310 The xNF Package **MUST** include all relevant Chef artifacts
2833 (roles/cookbooks/recipes) required to execute xNF actions requested by
2834 ONAP for loading on appropriate Chef Server.
2836 R-26567 The xNF Package **MUST** include a run list of
2837 roles/cookbooks/recipes, for each supported xNF action, that will
2838 perform the desired xNF action in its entirety as specified by ONAP
2839 (see Section 7.c, ONAP Controller APIs and Behavior, for list of xNF
2840 actions and requirements), when triggered by a chef-client run list
2843 R-98911 The xNF **MUST NOT** use any instance specific parameters
2844 for the xNF in roles/cookbooks/recipes invoked for a xNF action.
2846 R-37929 The xNF **MUST** accept all necessary instance specific
2847 data from the environment or node object attributes for the xNF
2848 in roles/cookbooks/recipes invoked for a xNF action.
2850 R-62170 The xNF **MUST** over-ride any default values for
2851 configurable parameters that can be set by ONAP in the roles,
2852 cookbooks and recipes.
2854 R-78116 The xNF **MUST** update status on the Chef Server
2855 appropriately (e.g., via a fail or raise an exception) if the
2856 chef-client run encounters any critical errors/failures when
2857 executing a xNF action.
2859 R-44013 The xNF **MUST** populate an attribute, defined as node
2860 [‘PushJobOutput’] with the desired output on all nodes in the push job
2861 that execute chef-client run if the xNF action requires the output of a
2862 chef-client run be made available (e.g., get running configuration).
2864 R-30654 The xNF Package **MUST** have appropriate cookbooks that are
2865 designed to automatically ‘rollback’ to the original state in case of
2866 any errors for actions that change state of the xNF (e.g., configure).
2868 R-65755 The xNF **SHOULD** support callback URLs to return information
2869 to ONAP upon completion of the chef-client run for any chef-client run
2870 associated with a xNF action.
2872 R-15885 The xNF **MUST** Upon completion of the chef-client run,
2873 POST back on the callback URL, a JSON object as described in Table
2874 A2 if the chef-client run list includes a cookbook/recipe that is
2875 callback capable. Failure to POST on the Callback Url should not be
2876 considered a critical error. That is, if the chef-client successfully
2877 completes the xNF action, it should reflect this status on the Chef
2878 Server regardless of whether the Callback succeeded or not.
2880 R-32217 The xNF **MUST** have routable FQDNs that are reachable via
2881 the Ansible Server for the endpoints (VMs) of a xNF on which playbooks
2882 will be executed. ONAP will initiate requests to the Ansible Server
2883 for invocation of playbooks against these end points [4]_.
2885 R-54373 The xNF **MUST** have Python >= 2.6 on the endpoint VM(s)
2886 of a xNF on which an Ansible playbook will be executed.
2888 R-35401 The xNF **MUST** support SSH and allow SSH access by the
2889 Ansible server for the endpoint VM(s) and comply with the Network
2890 Cloud Service Provider guidelines for authentication and access.
2892 R-82018 The xNF **MUST** load the Ansible Server SSH public key onto xNF
2893 VM(s) as part of instantiation. This will allow the Ansible Server
2894 to authenticate to perform post-instantiation configuration without
2895 manual intervention and without requiring specific xNF login IDs
2898 R-92866 The xNF **MUST** include as part of post-instantiation configuration
2899 done by Ansible Playbooks the removal/update of the SSH public key from
2900 /root/.ssh/authorized_keys, and update of SSH keys loaded through
2901 instantiation to support Ansible. This may include download and install of
2902 new SSH keys and new mechanized IDs.
2904 R-91745 The xNF **MUST** update the Ansible Server and other entities
2905 storing and using the SSH keys for authentication when the SSH keys used
2906 by Ansible are regenerated/updated.
2908 R-40293 The xNF **MUST** make available playbooks that conform
2909 to the ONAP requirement.
2911 R-49396 The xNF **MUST** support each ONAP (APPC) xNF action by invocation
2912 of **one** playbook [7]_. The playbook will be responsible
2913 for executing all necessary tasks (as well as calling other playbooks)
2914 to complete the request.
2916 R-33280 The xNF **MUST NOT** use any instance specific parameters
2919 R-48698 The xNF **MUST** utilize information from key value pairs
2920 that will be provided by the Ansible Server as "extra-vars" during
2921 invocation to execute the desired xNF action. If the playbook requires
2922 files, they must also be supplied using the methodology detailed in
2923 the Ansible Server API, unless they are bundled with playbooks, example,
2926 R-43253 The xNF **MUST** use playbooks designed to allow Ansible
2927 Server to infer failure or success based on the “PLAY_RECAP” capability.
2928 NOTE: There are cases where playbooks need to interpret results of a task
2929 and then determine success or failure and return result accordingly
2930 (failure for failed tasks).
2932 R-50252 The xNF **MUST** write to a specific one text files that
2933 will be retrieved and made available by the Ansible Server if, as part
2934 of a xNF action (e.g., audit), a playbook is required to return any
2935 xNF information. The text files must be written in the same directory as
2936 the one from which the playbook is being executed. A text file must be
2937 created for the xNF playbook run targets/affects, with the name
2938 ‘<VNFname>_results.txt’ into which any desired output from each
2939 respective VM/xNF must be written.
2941 R-51442 The xNF **SHOULD** use playbooks that are designed to
2942 automatically ‘rollback’ to the original state in case of any errors
2943 for actions that change state of the xNF (e.g., configure).
2945 R-58301 The xNF **SHOULD NOT** use playbooks that make requests to
2946 Cloud resources e.g. Openstack (nova, neutron, glance, heat, etc.);
2947 therefore, there is no use for Cloud specific variables like Openstack
2948 UUIDs in Ansible Playbooks.
2950 R-02651 The xNF **SHOULD** use the Ansible backup feature to save a
2951 copy of configuration files before implementing changes to support
2952 operations such as backing out of software upgrades, configuration
2953 changes or other work as this will help backing out of configuration
2954 changes when needed.
2956 R-43353 The xNF **MUST** return control from Ansible Playbooks only
2957 after tasks are fully complete, signaling that the playbook completed
2958 all tasks. When starting services, return control only after all services
2959 are up. This is critical for workflows where the next steps are dependent
2961 R-51910 The xNF **MUST** provide all telemetry (e.g., fault event
2962 records, syslog records, performance records etc.) to ONAP using the
2963 model, format and mechanisms described in this section.
2965 R-19624 The xNF **MUST** encode and serialize content delivered to
2966 ONAP using JSON (RFC 7159) plain text format. High-volume data is to
2967 be encoded and serialized using `Avro <http://avro.apache.org/>`_,
2968 where the Avro [6]_ data format are described using JSON.
2972 - JSON plain text format is preferred for moderate volume data sets
2973 (option 1), as JSON has the advantage of having well-understood simple
2974 processing and being human-readable without additional decoding. Examples
2975 of moderate volume data sets include the fault alarms and performance
2976 alerts, heartbeat messages, measurements used for xNF scaling and syslogs.
2977 - Binary format using Avro is preferred for high volume data sets
2978 (option 2) such as mobility flow measurements and other high-volume
2979 streaming events (such as mobility signaling events or SIP signaling)
2980 or bulk data, as this will significantly reduce the volume of data
2981 to be transmitted. As of the date of this document, all events are
2982 reported using plain text JSON and REST.
2983 - Avro content is self-documented, using a JSON schema. The JSON schema is
2984 delivered along with the data content
2985 (http://avro.apache.org/docs/current/ ). This means the presence and
2986 position of data fields can be recognized automatically, as well as the
2987 data format, definition and other attributes. Avro content can be
2988 serialized as JSON tagged text or as binary. In binary format, the
2989 JSON schema is included as a separate data block, so the content is
2990 not tagged, further compressing the volume. For streaming data, Avro
2991 will read the schema when the stream is established and apply the
2992 schema to the received content.
2994 R-98191 The xNF **MUST** vary the frequency that asynchronous data is
2995 delivered based on the content and how data may be aggregated or grouped
3000 - For example, alarms and alerts are expected to be delivered as soon
3001 as they appear. In contrast, other content, such as performance
3002 measurements, KPIs or reported network signaling may have various ways
3003 of packaging and delivering content. Some content should be streamed
3004 immediately; or content may be monitored over a time interval, then packaged
3005 as collection of records and delivered as block; or data may be collected
3006 until a package of a certain size has been collected; or content may be
3007 summarized statistically over a time interval, or computed as a KPI, with
3008 the summary or KPI being delivered.
3009 - We expect the reporting frequency to be configurable depending
3010 on the virtual network function’s needs for management. For example,
3011 Service Provider may choose to vary the frequency of collection between
3012 normal and trouble-shooting scenarios.
3013 - Decisions about the frequency of data reporting will affect the
3014 size of delivered data sets, recommended delivery method, and how the
3015 data will be interpreted by ONAP. These considerations should not
3016 affect deserialization and decoding of the data, which will be guided
3017 by the accompanying JSON schema or GPB definition files.
3019 R-88482 The xNF **SHOULD** use REST using HTTPS delivery of plain
3020 text JSON for moderate sized asynchronous data sets, and for high
3021 volume data sets when feasible.
3023 R-84879 The xNF **MUST** have the capability of maintaining a primary
3024 and backup DNS name (URL) for connecting to ONAP collectors, with the
3025 ability to switch between addresses based on conditions defined by policy
3026 such as time-outs, and buffering to store messages until they can be
3027 delivered. At its discretion, the service provider may choose to populate
3028 only one collector address for a xNF. In this case, the network will
3029 promptly resolve connectivity problems caused by a collector or network
3030 failure transparently to the xNF.
3032 R-81777 The xNF **MUST** be configured with initial address(es) to use
3033 at deployment time. Subsequently, address(es) may be changed through
3034 ONAP-defined policies delivered from ONAP to the xNF using PUTs to a
3035 RESTful API, in the same manner that other controls over data reporting
3036 will be controlled by policy.
3038 R-08312 The xNF **MAY** use another option which is expected to include REST
3039 delivery of binary encoded data sets.
3041 R-79412 The xNF **MAY** use another option which is expected to include TCP
3042 for high volume streaming asynchronous data sets and for other high volume
3043 data sets. TCP delivery can be used for either JSON or binary encoded data
3046 R-01033 The xNF **MAY** use another option which is expected to include SFTP
3047 for asynchronous bulk files, such as bulk files that contain large volumes of
3048 data collected over a long time interval or data collected across many xNFs.
3049 (Preferred is to reorganize the data into more frequent or more focused data
3050 sets, and deliver these by REST or TCP as appropriate.)
3052 R-63229 The xNF **MAY** use another option which is expected to include REST
3053 for synchronous data, using RESTCONF (e.g., for xNF state polling).
3055 R-03070 The xNF **MUST**, by ONAP Policy, provide the ONAP addresses
3056 as data destinations for each xNF, and may be changed by Policy while
3057 the xNF is in operation. We expect the xNF to be capable of redirecting
3058 traffic to changed destinations with no loss of data, for example from
3059 one REST URL to another, or from one TCP host and port to another.
3061 R-06924 The xNF **MUST** deliver asynchronous data as data becomes
3062 available, or according to the configured frequency.
3064 R-73285 The xNF **MUST** must encode, address and deliver the data
3065 as described in the previous paragraphs.
3067 R-42140 The xNF **MUST** respond to data requests from ONAP as soon
3068 as those requests are received, as a synchronous response.
3070 R-34660 The xNF **MUST** use the RESTCONF/NETCONF framework used by
3071 the ONAP configuration subsystem for synchronous communication.
3073 R-86586 The xNF **MUST** use the YANG configuration models and RESTCONF
3074 [RFC8040] (https://tools.ietf.org/html/rfc8040).
3076 R-11240 The xNF **MUST** respond with content encoded in JSON, as
3077 described in the RESTCONF specification. This way the encoding of a
3078 synchronous communication will be consistent with Avro.
3080 R-70266 The xNF **MUST** respond to an ONAP request to deliver the
3081 current data for any of the record types defined in
3082 Event Records - Data Structure Description by returning the requested
3083 record, populated with the current field values. (Currently the defined
3084 record types include fault fields, mobile flow fields, measurements for
3085 xNF scaling fields, and syslog fields. Other record types will be added
3086 in the future as they become standardized and are made available.)
3088 R-46290 The xNF **MUST** respond to an ONAP request to deliver granular
3089 data on device or subsystem status or performance, referencing the YANG
3090 configuration model for the xNF by returning the requested data elements.
3092 R-43327 The xNF **SHOULD** use `Modeling JSON text with YANG
3093 <https://tools.ietf.org/html/rfc7951>`_, If YANG models need to be
3094 translated to and from JSON[RFC7951]. YANG configuration and content can
3095 be represented via JSON, consistent with Avro, as described in “Encoding
3096 and Serialization” section.
3098 R-42366 The xNF **MUST** support secure connections and transports such as
3099 Transport Layer Security (TLS) protocol
3100 [`RFC5246 <https://tools.ietf.org/html/rfc5246>`_] and should adhere to
3101 the best current practices outlined in
3102 `RFC7525 <https://tools.ietf.org/html/rfc7525>`_.
3104 R-44290 The xNF **MUST** control access to ONAP and to xNFs, and creation
3105 of connections, through secure credentials, log-on and exchange mechanisms.
3107 R-47597 The xNF **MUST** carry data in motion only over secure connections.
3109 R-68165 The xNF **MUST** encrypt any content containing Sensitive Personal
3110 Information (SPI) or certain proprietary data, in addition to applying the
3111 regular procedures for securing access and delivery.
3114 Ansible Playbook Examples
3115 -----------------------------------------------
3117 The following sections contain examples of Ansible playbooks
3118 which follow the guidelines.
3120 Guidelines for Playbooks to properly integrate with APPC
3121 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3123 NOTE: To support concurrent requests to multiple VNF instances of same
3124 or different type, VNF hosts and other files with VNF specific default
3125 values are kept or created in separate directories.
3127 Example of an Ansible command (after pwd) to run playbook again
3128 vfdb9904v VNF instance:
3130 .. code-block:: none
3133 /storage/vfdb/V16.1/ansible/configure
3134 $ ansible-playbook -i ../inventory/vfdb9904vhosts site.yml --extra-vars "vnf_instance=vfdb9904v"
3136 NOTE: To preserve Ansible inventory/group_vars capability, that makes
3137 group_vars contents global variables available to all playbooks, when they
3138 reside in the inventory directory, guidelines are being updated to name the
3139 VNF inventory hosts file as (a flat file) <VNFName>hosts, stored in the
3140 inventory directory, not a subdirectory under inventory. In the above
3141 example: vfdb9904vhosts (removed / VNF name and hosts vfdb9904/vhosts)
3143 Example of corresponding APPC API Call from ONAP – Ansible Server
3146 An example of a curl request simulating a Rest API POST requesting execution
3147 of configure Playbook (using playbook relative path):
3149 .. code-block:: none
3151 curl -u APIUser:APIPassword -H "Content-type:application/json" -X POST
3152 -d '{"Id": "8412", "PlaybookName": "vfdb/V5.x.x/ansible/configure/site.yml",
3153 "Timeout":"600", "EnvParameters": { "vnf_instance": "vfdb9904v" }}'
3154 http://ansible.server.com:5000/Dispatch
3156 Rest API GET request to obtain response/results for prior request
3157 (same Id as POST request above):
3159 .. code-block:: none
3161 curl -u APIUser:APIPassword -H 'Content-type: application/json' -X GET
3162 'http://ansible.server.com:5000/Dispatch/?Id=8412&Type=GetResult'
3166 - An ID number is assigned to each request. This ID number is used to
3167 track request down to completion and provide status to APPC when
3170 - Playbook Name relative path provided in the request as PlaybookName
3172 - Ansible Server Rest API is aware of playbook’s root directory which may
3173 vary from instance to instance or Ansible Server cluster to cluster.
3175 Ansible Playbooks will use the VNF instance name (passed using
3176 --extra-vars "vnf\_instance=vfdb9904v") to identify other default values
3177 to run the playbook(s) against the target VNF instance. Same example as
3180 .. code-block:: none
3182 $ ansible-playbook -i ../inventory/vfdb9904vhosts site.yml --extra-vars "vnf_instance=vfdb9904v"
3184 Each Ansible Server or cluster is assigned its own identification to be used
3185 to authenticate to VNF VMs using Ansible Server or cluster specific set of
3186 SSH keys that may be rotated regularly. Here hosts file, no longer referencing
3187 file with SSH key credentials, to run ansible-playbook listed in this example
3188 above (IP addresses were scrubbed):
3190 .. code-block:: none
3192 $ more ../inventory/vfdb9904v/hosts
3194 localhost ansible_connection=local
3204 NOTE: APPC requests to run Playbooks/Cookbooks are specific to a VNF,
3205 but could be more limited to one VM or one type of VM by the request
3206 parameters. Actions that may impact a site (LCP), a service, or an
3207 entire platform must be orchestrated by MSO in order to execute requests
3208 via APPC which then invoke VNF level playbooks. Playbooks that impact
3209 more than a single VNF are not the current focus of these guidelines.
3211 Since last release of these guidelines, based on recent learnings,
3212 moving VNF Type global variables under inventory/group_vars files, this
3213 way variables and respective values are available to all playbooks without
3214 being explicitly referenced though an include statement. Also creating
3215 templates that are VNF Type specific, but moving away from static files
3216 that are VNF instance specific, working to obtain VNF instance specific
3217 from other sources, inventory database, etc.
3219 And here the scrubbed default arguments for this VNF instance(originated
3220 from previously re-factored playbooks now being phased out):
3222 .. code-block:: none
3224 vnf_instance=vfdb9904v
3226 $ more ../vars/vfdb9904v/default_args.yml
3227 vm_config_oam_vnfc_name: vfdb9904vm001oam001
3228 vm_config_oam_hostname: vfdb9904vm001
3229 vm_config_oam_provider_ip_address: 1xx.2yy.zzz.109
3232 IMPORTANT: The APPC and default file attribute name for
3233 vm\_config\_oam\_vnfc\_name, as an example, is derived from vm\_config
3234 array structure (list) in the CSAR package ENV file, with dots replaced
3237 .. code-block:: none
3241 oam: {vnfc_name: {{ vm_config_oam_vnfc_name }}, hostname: {{
3242 vm_config_oam_hostname }}, provider_ip_address: {{
3243 vm_config_oam_provider_ip_address }
3247 Parameters like VNF names, VNFC names, OA&M IP addresses, after
3248 February, 2018 ONAP release, will be extracted from A&AI by APPC and
3249 then passed down to Ansible Server, as part of APPC request through REST
3250 API. In the meantime, VNF instance specific required values, will
3251 be stored on VNF instance directory, default arguments file and will be
3252 used as defaults. For parameterized playbooks attribute-value pairs
3253 passed down by APPC to Ansible Server always take precedence over
3254 template or VNF instance specific defaults stored in defaults file(s).
3256 .. code-block:: none

3288 One of the first tasks on the Ansible Playbooks is to combine the VNF
3289 type generic template, derived from ENV files in CSAR or other files,
3290 with these default values stored on the Ansible Server, together with
3291 the overriding parameters passed down from APPC, to create the VNF
3292 instance specific set of attribute-value pairs to be used for the run, in
3293 INI format. Here is an excerpt from such a file that should look
3294 somewhat similar to ENV files:
3296 .. code-block:: none
3298 $ more tmp/vfdb9904v/all.yml
3300 deployment_prefix: vfdb9904v
3304 template_version: '2014-10-16'
3305 stack_name: vfdb9904v
3307 stackName: vfdb9904v
3311 # logins list contain 'login name', 'login group', 'login password'
3313 .. code-block:: none
3316 - { name: 'm99999', group: 'm99999', password: 'abcdefgha' }
3317 - { name: 'gsuser', group: 'gsuser', password: ' abcdefgha' }
3318 - { name: 'peruser', group: 'peruser', password: ' abcdefgha' }
3319 - { name: 'dbuser', group: 'dbuser', password: ' abcdefgha' }
3321 NOTE: Arguments passed by APPC to Ansible Server to run a playbook take
3322 precedence over any defaults stored in Ansible Server.
3324 Ansible Playbooks – Notes On Artifacts Required to Run Playbooks
3325 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3327 Inventory hosts file: should be VNF instance specific.
3329 Default variables: should be VNF instance specific.
3331 NOTE: Some playbooks may rely on inventory directory contents to target
3332 the collection of VNFs in the Services Platform supported through
3335 Playbooks and paths to referenced files: Playbooks shall not use
3336 absolute paths in include or import entries (variables or playbooks) or
3337 other types of references.
3339 For this to work properly, when running playbooks, the directory where
3340 the main playbook resides shall be the current directory.
3342 Playbook imports, when used, shall use paths relative to the main
3345 Root directory named ansible - Any files provided with playbooks,
3346 included, imported, or referenced by playbooks, shall reside under the ansible
3347 playbooks (root) directory, containing all playbook subdirectories, or
3348 below that ansible root directory, in other subdirectories to support
3349 on-boarding and portability of VNF collection of playbooks and related
3352 Designing for a shared environment, concurrently running playbooks,
3353 targeting multiple VNF instances – inventory hosts file:
3355 To avoid inventory hosts file overwrites or collisions between multiple
3356 concurrently running VNF instance requests, chosen approach is for each
3357 VNF instance hosts file, to be stored under the Ansible Server Playbooks
3358 root directory, under the inventory subdirectory, and under a directory
3359 for each VNF instance, named after the VNF instance, as follows:
3361 ansible/inventory/<VNF\_instance\_name>/hosts
3363 Example of inventory hosts file path, relative to ansible playbooks root
3364 directory (playbooks\_dir): ansible/inventory/vnfx0001v/hosts
3366 **Designing for a shared environment, concurrently running multiple playbooks,
3367 targeting multiple VNF instances – default argument variables for
3368 specific VNF instances:**
3370 Files containing attribute name value pairs (variable name and default
3371 values), referenced/included by playbooks – Files containing VNF
3372 instance specific default values – in a later APPC release, some or all
3373 the default attribute value pairs contained in the defaults file, may be
3374 passed down by APPC, to the Ansible Server, overriding these defaults:
3376 VNF instance specific files
3377 referenced/included by playbooks, containing default values, example,
3378 default\_args.yml, shall be stored under a directory with VNF instance
3383 ansible/vars/<VNF\_instance\_name>/default\_args.yml
3385 Example of include statement:
3387 - include_vars: ../vars/{{ vnf_instance }}/default_args.yml
3389 Again, this was originated from previously re-factored playbooks, now being
3390 phased out, to move away from having to create VNF instance specific files
3391 with VNF instance default variables. Moving to extract these values from
3392 inventory databases and provide them to Ansible Server as part of the APPC
3393 request, but may be used in a transition from having everything stored in the
3394 Ansible Server to APPC extracting and providing VNF instance specific
3395 attribute-value pairs to the Ansible Server as part of the request.
3397 Files containing attribute name value pairs (variable name and default
3398 values), referenced/included by playbooks – created dynamically by
3402 overwrites or collisions of multiple concurrently running VNF instance
3403 requests, files created dynamically by playbooks, based on VNF generic
3404 templates, combined with default values and arguments passed down by
3405 APPC (as part of the request), shall be stored under a directory with
3406 VNF instance name on the path.
3410 tmp/<VNF\_instance\_name>/all.yml
3412 Files containing site specific (Openstack location non-instance
3413 specific) attribute name value pairs, like NTP server and DNS server’s
3414 IP addresses and other parameters, referenced/included by playbooks, not
3415 VNF specific – Could/should be stored under inventory/group_vars directory,
3416 in a subdirectory named after the string used to identify the site (nyc1,
3421 ansible/inventory/group_vars/<Site>
3423 ansible/inventory/group_vars/nyc1
3425 ansible/inventory/group_vars/lax2
3428 \ **Ansible Server Design - Directory Structure**
3430 To help understanding the contents of this section, here are few basic
3433 **VNF type a.k.a VNF Function Code** - Based on current Services
3434 Platform naming convention, each Virtual Network Function is assigned a
3435 4 character string (example vfdb), these are 4 characters in
3436 the VNF instance name, followed by (4) numbers, ending in a "v", but the
3437 naming convention is evolving. VNF instance name in
3438 some cases corresponds to the stack name for the VNF when VNF instance
3439 is built based on a single module, single stack. Example of VNF instance
3440 name: vfdb9904v. All VNF performing this function, running the same
3441 software, coming from the same VNF provider will have the same 4
3442 characters in the VNF instance name, in this example, vfdb.
3444 NOTE: New naming convention includes a prefix indicating geographical
3445 location where VNF is instantiated.
3447 VNF type, determined through these 4 characters, is also known as VNF
3448 Function Code and is assigned by inventory team. All Services Platform
3449 VNF Function Codes can be found in inventory database and/or A&AI as
3450 well as Services Platform Network Design Documents.
3452 Version – As in VNF software version is the release of the software
3453 running on the VNF for which the playbooks were developed. VNF
3454 configuration steps may change from release to release and this
3455 <Version> in the path will allow the Ansible Server to host playbooks
3456 associated with each software release. And run the playbooks that match
3457 the software release running on each VNF instance. APPC initially will
3458 not support playbook versioning only latest playbook is supported or a hard
3459 coded version that later should become a variable to allow multiple
3460 actively in use playbook versions according to VNF release.
3462 Playbook Function - Is a name associated with a life cycle management
3463 task(s) performed by the playbook(s) stored in this directory. It should
3464 clearly identify the type of action(s) performed by the main playbook
3465 and possibly other playbooks stored in this same directory. Ideally,
3466 playbook function would match APPC corresponding command or function that
3467 is performed by the main playbook in this directory. Following Ansible naming
3468 standards main playbook is usually named site.yml. There can be other
3469 playbooks on the same directory that use a subset of the roles used by the
3470 main playbook site.yml. Examples of Playbook Function directory names:
3472 - configure – Contains post-instantiation (bulk) configuration
3475 - healthcheck – Contains VNF health check playbook(s), roles,…
3477 - stop – Contains VNF application stop (stopApplication) playbook(s),
3480 - start – Contains VNF application start (startApplication) playbook(s),
3483 Directory structure to allow hosting multiple version sets of playbooks,
3484 for the same VNF type, to be hosted in the runtime environment on the
3485 Ansible Servers. Generic directory structure:
3487 Ansible Playbooks – Function directory and main playbook:
3489 .. code-block:: none
3491 <VNF type>/<Version>/ansible/<Playbook Function>/site.yml
3493 Example – Post-instantiation (bulk) configuration –APPC Function -
3496 .. code-block:: none
3498 <VNF type>/<Version>/ansible/configure/site.yml
3500 Example – Post-instantiation (bulk) configuration –APPC Function
3501 – Configure – VNF software version 16.1:
3503 .. code-block:: none
3505 vfdb/V16.1/ansible/configure/site.yml
3507 Example – Health-check –APPC Function - HealthCheck:
3509 .. code-block:: none
3511 <VNF type>/<Version>/ansible/healthcheck/site.yml
3513 OR (Function directory name does not need to match APPC function name)
3515 .. code-block:: none
3517 <VNF type>/<Version>/ansible/check/site.yml
3519 Ansible Directories for other artifacts – VNF inventory hosts file -
3522 .. code-block:: none
3524 <VNF type>/<Version>/ansible/inventory/<VNF instance name>hosts
3526 Ansible Directories for other artifacts – VNF instance specific default
3527 arguments – Optional:
3529 .. code-block:: none
3531 <VNF type>/<Version>/ansible/group_vars/<VNF instance name>
3533 NOTE: This requirement is expected to be deprecated all or in part in the
3534 future, for automated actions, once APPC can pass down all VNF specific
3535 arguments for each action. Requirement remains while manual actions are
3536 to be supported. Other automated inventory management mechanisms may be
3537 considered in the future, Ansible supports many automated inventory
3538 management mechanisms/tools/solutions.
3540 Ansible Directories for other artifacts – VNF (special) groups –
3543 .. code-block:: none
3545 <VNF type>/<Version>/ansible/inventory/group_vars/<VNF instance name>
3547 NOTE: Default groups will be created based on VNFC type, 3 characters,
3548 on VNFC name. Example: “oam”, “rdb”, “dbs”, “man”, “iox”, “app”,…
3550 Ansible Directories for other artifacts – VNF (special) other files –
3551 Optional – Example – License file:
3553 .. code-block:: none
3555 <VNF type>/<Version>/ansible/<Other directory(s)>
3557 CAUTION: On referenced files used/required by playbooks.
3559 - To avoid missing files, during on-boarding or uploading of Ansible
3560 Playbooks and related artifacts, all permanent files (not generated
3561 by playbooks as part of execution), required to run any playbook,
3562 shall reside under the ansible root directory or below on other
3565 - Any references to files, on includes or other playbook entries, shall
3568 - This is the ansible (root) directory referenced on this
3569 note (Ansible Server mount point not included):
3571 .. code-block:: none
3573 <VNF type>/<Version>/ansible/
3575 There will be a soft link to the latest set of Ansible Playbooks for
3578 VNF type directories use A&AI inventory VNF function code. Ansible
3579 Playbooks will be stored on a Cinder Volume mounted on the Ansible
3580 Servers as /storage. Example:
3582 /storage/vfdb/latest/ansible – This soft link point to the latest set of
3583 playbooks (or the only set)
3585 /storage/vfdb/V16.1/ansible – Root directory for database VNF Ansible
3586 Playbooks for release 16.1
3588 CAUTION: To support this directory structure as the repository to store
3589 Ansible Playbooks run by APPC, APPC API in the Ansible Server side needs
3590 to be configured to run playbooks from directory, not MySQL database.
3592 Ansible Server HTTP will be configured to support APPC REST API requests
3593 to run playbooks as needed, against specific VNF instances, or specific
3594 VM(s) as specified in the request.
3596 ONAP APPC REST API to Ansible Server is documented separately and can be
3597 found under ONAP (onap.org).
3599 **Ansible Server – On-boarding Ansible Playbooks**
3601 Once playbooks are developed following the guidelines listed in prior
3602 section(s), playbooks need to be on-boarded onto Ansible Server(s). In
3603 the future, they’ll be on-boarded and distributed through ONAP, at least
3604 that is the proposed plan, but for now they need to be uploaded
3605 manually. There is work in progress to use a Git as the playbook
3606 repository to store and track playbooks by version, version control.
3608 These are the basic steps to on-board playbooks manually onto the
3611 1. Upload CSAR, zip, or tar file containing VNF playbooks and related
3614 2. Create full directory (using –p option below) to store Ansible
3615 Playbooks and other artifacts under /storage (or other configured)
3618 a. Includes VNF type using VNF function code 4 characters under
3621 b. Includes VNF “Version” directory as part of the path to store
3622 playbooks for this VNF version.
3624 c. Include generic ansible root directory. Creating full directory
3627 .. code-block:: none
3629 $ mkdir –p /storage/vfdb/V16.1/ansible**/**
3631 3. Make this directory (VNF ansible root directory) current directory
3634 .. code-block:: none
3636 cd /storage/vfdb/V16.1/ansible/
3638 4. Extract Ansible Playbooks and other Ansible artifacts associated with
3639 the playbooks onto the ansible directory. Command depends on the type
3640 of file uploaded, examples would be:
3642 .. code-block:: none
3648 5. Create VNF inventory hosts file with all VMs and
3649 OA&M IP addresses for all VNF instances with known OA&M IP addresses
3650 for respective VMs, example:
3652 .. code-block:: none
3656 $ touch inventory/vfdb9904vhosts
3658 $ cat inventory/vfdb9904vhosts
3661 localhost ansible\_connection=local
3671 6. (Optional, being deprecated) Create directory to hold default
3672 arguments for each VNF instance,
3675 .. code-block:: none
3677 $ mkdir –p vars/vfdb9904v
3678 $ touch vars/vfdb9904v/default\_args.yml
3679 $ cat vars/vfdb9904v/default\_args.yml
3680 vm\_config\_oam1\_vnfc\_name: vfdb9904vm001oam001
3681 vm\_config\_oam1\_hostname: vfdb9904vm001
3682 vm\_config\_oam1\_provider\_ip\_address: 1xx.2yy.zzz.109
3684 vm\_config\_oam2\_vnfc\_name: vfdb9904vm002oam001
3685 vm\_config\_oam2\_hostname: vfdb9904vm002
3686 vm\_config\_oam2\_provider\_ip\_address: 1xx.2yy.zzz.110
3688 vm\_config\_rdb1\_vnfc\_name: vfdb9904vm003rdb001
3689 vm\_config\_rdb1\_hostname: vfdb9904vm003
3690 vm\_config\_rdb1\_provider\_ip\_address: 1xx.2yy.zzz.105
3692 vm\_config\_rdb2\_vnfc\_name: vfdb9904vm004rdb001
3693 vm\_config\_rdb2\_hostname: vfdb9904vm004
3694 vm\_config\_rdb2\_provider\_ip\_address: 1xx.2yy.zzz.106
3696 vm\_config\_rdb3\_vnfc\_name: vfdb9904vm005rdb001
3697 vm\_config\_rdb3\_hostname: vfdb9904vm005
3698 vm\_config\_rdb3\_provider\_ip\_address: 1xx.2yy.zzz.xxx
3700 vm\_config\_rdb4\_vnfc\_name: vfdb9904vm006rdb001
3701 vm\_config\_rdb4\_hostname: vfdb9904vm006
3702 vm\_config\_rdb4\_provider\_ip\_address: 1xx.2yy.zzz.yyy
3704 NOTE: Please note names in this file shall use underscore “\_” not dots
3707 7. Perform some basic playbook validation running with “--check” option,
3708 running dummy playbooks or other.
3710 NOTE: Each Ansible Server or cluster of Ansible Server will have its own
3711 credentials to authenticate to VNF VMs. Ansible Server SSH public key(s)
3712 have to be loaded onto VNF VMs during instantiation or other way before
3713 Ansible Server can access VNF VMs and run playbooks. HOT templates used
3714 by heat to instantiate VNFs to be configured by these Ansible Servers running
3715 playbooks shall include the same SSH public key and load them onto VNF VM(s)
3716 as part of instantiation.
3718 Other non-vendor specific playbook tasks need to be incorporated in overall
3719 post-instantiation configuration playbook. Alternative is for company
3720 developed playbooks to be uploaded and executed, after VNF vendor provided
