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-92935 The VNF **SHOULD** minimize the propagation of state information
992 across multiple data centers to avoid cross data center traffic.
994 R-26371 The VNF **MUST** detect communication failure for inter VNFC
995 instance and intra/inter VNF and re-establish communication
996 automatically to maintain the VNF without manual intervention to
997 provide service continuity.
999 R-18725 The VNF **MUST** handle the restart of a single VNFC instance
1000 without requiring all VNFC instances to be restarted.
1002 R-06668 The VNF **MUST** handle the start or restart of VNFC instances
1003 in any order with each VNFC instance establishing or re-establishing
1004 required connections or relationships with other VNFC instances and/or
1005 VNFs required to perform the VNF function/role without requiring VNFC
1006 instance(s) to be started/restarted in a particular order.
1008 R-80070 The VNF **MUST** handle errors and exceptions so that they do
1009 not interrupt processing of incoming VNF requests to maintain service
1010 continuity (where the error is not directly impacting the software
1011 handling the incoming request).
1013 R-32695 The VNF **MUST** provide the ability to modify the number of
1014 retries, the time between retries and the behavior/action taken after
1015 the retries have been exhausted for exception handling to allow the
1016 NCSP to control that behavior, where the interface and/or functional
1017 specification allows for altering behaviour.
1019 R-48356 The VNF **MUST** fully exploit exception handling to the extent
1020 that resources (e.g., threads and memory) are released when no longer
1021 needed regardless of programming language.
1023 R-67918 The VNF **MUST** handle replication race conditions both locally
1024 and geo-located in the event of a data base instance failure to maintain
1027 R-36792 The VNF **MUST** automatically retry/resubmit failed requests
1028 made by the software to its downstream system to increase the success rate.
1030 R-22059 The VNF **MUST NOT** execute long running tasks (e.g., IO,
1031 database, network operations, service calls) in a critical section
1032 of code, so as to minimize blocking of other operations and increase
1033 concurrent throughput.
1035 R-63473 The VNF **MUST** automatically advertise newly scaled
1036 components so there is no manual intervention required.
1038 R-74712 The VNF **MUST** utilize FQDNs (and not IP address) for
1039 both Service Chaining and scaling.
1041 R-41159 The VNF **MUST** deliver any and all functionality from any
1042 VNFC in the pool (where pooling is the most suitable solution). The
1043 VNFC pool member should be transparent to the client. Upstream and
1044 downstream clients should only recognize the function being performed,
1045 not the member performing it.
1047 R-85959 The VNF **SHOULD** automatically enable/disable added/removed
1048 sub-components or component so there is no manual intervention required.
1050 R-06885 The VNF **SHOULD** support the ability to scale down a VNFC pool
1051 without jeopardizing active sessions. Ideally, an active session should
1052 not be tied to any particular VNFC instance.
1054 R-12538 The VNF **SHOULD** support load balancing and discovery
1055 mechanisms in resource pools containing VNFC instances.
1057 R-98989 The VNF **SHOULD** utilize resource pooling (threads,
1058 connections, etc.) within the VNF application so that resources
1059 are not being created and destroyed resulting in resource management
1062 R-55345 The VNF **SHOULD** use techniques such as “lazy loading” when
1063 initialization includes loading catalogues and/or lists which can grow
1064 over time, so that the VNF startup time does not grow at a rate
1065 proportional to that of the list.
1067 R-35532 The VNF **SHOULD** release and clear all shared assets (memory,
1068 database operations, connections, locks, etc.) as soon as possible,
1069 especially before long running sync and asynchronous operations, so as
1070 to not prevent use of these assets by other entities.
1072 R-77334 The VNF **MUST** allow configurations and configuration parameters
1073 to be managed under version control to ensure consistent configuration
1074 deployment, traceability and rollback.
1076 R-99766 The VNF **MUST** allow configurations and configuration parameters
1077 to be managed under version control to ensure the ability to rollback to
1078 a known valid configuration.
1080 R-73583 The VNF **MUST** allow changes of configuration parameters
1081 to be consumed by the VNF without requiring the VNF or its sub-components
1082 to be bounced so that the VNF availability is not effected.
1084 R-21558 The VNF **SHOULD** use intelligent routing by having knowledge
1085 of multiple downstream/upstream endpoints that are exposed to it, to
1086 ensure there is no dependency on external services (such as load balancers)
1087 to switch to alternate endpoints.
1089 R-08315 The VNF **SHOULD** use redundant connection pooling to connect
1090 to any backend data source that can be switched between pools in an
1091 automated/scripted fashion to ensure high availability of the connection
1094 R-27995 The VNF **SHOULD** include control loop mechanisms to notify
1095 the consumer of the VNF of their exceeding SLA thresholds so the consumer
1096 is able to control its load against the VNF.
1098 R-73364 The VNF **MUST** support at least two major versions of the
1099 VNF software and/or sub-components to co-exist within production
1100 environments at any time so that upgrades can be applied across
1101 multiple systems in a staggered manner.
1103 R-02454 The VNF **MUST** support the existence of multiple major/minor
1104 versions of the VNF software and/or sub-components and interfaces that
1105 support both forward and backward compatibility to be transparent to
1106 the Service Provider usage.
1108 R-57855 The VNF **MUST** support hitless staggered/rolling deployments
1109 between its redundant instances to allow "soak-time/burn in/slow roll"
1110 which can enable the support of low traffic loads to validate the
1111 deployment prior to supporting full traffic loads.
1113 R-64445 The VNF **MUST** support the ability of a requestor of the
1114 service to determine the version (and therefore capabilities) of the
1115 service so that Network Cloud Service Provider can understand the
1116 capabilities of the service.
1118 R-56793 The VNF **MUST** test for adherence to the defined performance
1119 budgets at each layer, during each delivery cycle with delivered
1120 results, so that the performance budget is measured and the code
1121 is adjusted to meet performance budget.
1123 R-77667 The VNF **MUST** test for adherence to the defined performance
1124 budget at each layer, during each delivery cycle so that the performance
1125 budget is measured and feedback is provided where the performance budget
1128 R-49308 The VNF **SHOULD** test for adherence to the defined resiliency
1129 rating recommendation at each layer, during each delivery cycle with
1130 delivered results, so that the resiliency rating is measured and the
1131 code is adjusted to meet software resiliency requirements.
1133 R-16039 The VNF **SHOULD** test for adherence to the defined
1134 resiliency rating recommendation at each layer, during each
1135 delivery cycle so that the resiliency rating is measured and
1136 feedback is provided where software resiliency requirements are
1139 R-34957 The VNF **MUST** provide a method of metrics gathering for each
1140 layer's performance to identify/document variances in the allocations so
1141 they can be addressed.
1143 R-49224 The VNF **MUST** provide unique traceability of a transaction
1144 through its life cycle to ensure quick and efficient troubleshooting.
1146 R-52870 The VNF **MUST** provide a method of metrics gathering
1147 and analysis to evaluate the resiliency of the software from both
1148 a granular as well as a holistic standpoint. This includes, but is
1149 not limited to thread utilization, errors, timeouts, and retries.
1151 R-92571 The VNF **MUST** provide operational instrumentation such as
1152 logging, so as to facilitate quick resolution of issues with the VNF to
1153 provide service continuity.

2584 R-62468 The xNF **MUST** allow all configuration data to be
2585 edited through a NETCONF <edit-config> operation. Proprietary
2586 NETCONF RPCs that make configuration changes are not sufficient.
2588 R-01382 The xNF **MUST** allow the entire configuration of the
2589 xNF to be retrieved via NETCONF's <get-config> and <edit-config>,
2590 independently of whether it was configured via NETCONF or other
2593 R-28756 The xNF **MUST** support **:partial-lock** and
2594 **:partial-unlock** capabilities, defined in RFC 5717. This
2595 allows multiple independent clients to each write to a different
2596 part of the <running> configuration at the same time.
2598 R-83873 The xNF **MUST** support **:rollback-on-error** value for
2599 the <error-option> parameter to the <edit-config> operation. If any
2600 error occurs during the requested edit operation, then the target
2601 database (usually the running configuration) will be left unaffected.
2602 This provides an 'all-or-nothing' edit mode for a single <edit-config>
2605 R-68990 The xNF **MUST** support the **:startup** capability. It
2606 will allow the running configuration to be copied to this special
2607 database. It can also be locked and unlocked.
2609 R-68200 The xNF **MUST** support the **:url** value to specify
2610 protocol operation source and target parameters. The capability URI
2611 for this feature will indicate which schemes (e.g., file, https, sftp)
2612 that the server supports within a particular URL value. The 'file'
2613 scheme allows for editable local configuration databases. The other
2614 schemes allow for remote storage of configuration databases.
2616 R-20353 The xNF **MUST** implement both **:candidate** and
2617 **:writable-running** capabilities. When both **:candidate** and
2618 **:writable-running** are provided then two locks should be supported.
2620 R-11499 The xNF **MUST** fully support the XPath 1.0 specification
2621 for filtered retrieval of configuration and other database contents.
2622 The 'type' attribute within the <filter> parameter for <get> and
2623 <get-config> operations may be set to 'xpath'. The 'select' attribute
2624 (which contains the XPath expression) will also be supported by the
2625 server. A server may support partial XPath retrieval filtering, but
2626 it cannot advertise the **:xpath** capability unless the entire XPath
2627 1.0 specification is supported.
2629 R-83790 The xNF **MUST** implement the **:validate** capability
2631 R-49145 The xNF **MUST** implement **:confirmed-commit** If

2644 and the mapping to NETCONF shall follow the rules defined in this RFC.
2646 R-26115 The xNF **MUST** follow the data model upgrade rules defined
2647 in [RFC6020] section 10. All deviations from section 10 rules shall
2648 be handled by a built-in automatic upgrade mechanism.
2650 R-10716 The xNF **MUST** support parallel and simultaneous
2651 configuration of separate objects within itself.
2653 R-29495 The xNF **MUST** support locking if a common object is
2654 being manipulated by two simultaneous NETCONF configuration operations
2655 on the same xNF within the context of the same writable running data
2656 store (e.g., if an interface parameter is being configured then it
2657 should be locked out for configuration by a simultaneous configuration
2658 operation on that same interface parameter).
2660 R-53015 The xNF **MUST** apply locking based on the sequence of
2661 NETCONF operations, with the first configuration operation locking
2662 out all others until completed.
2664 R-02616 The xNF **MUST** permit locking at the finest granularity
2665 if a xNF needs to lock an object for configuration to avoid blocking
2666 simultaneous configuration operations on unrelated objects (e.g., BGP
2667 configuration should not be locked out if an interface is being
2668 configured or entire Interface configuration should not be locked out
2669 if a non-overlapping parameter on the interface is being configured).
2671 R-41829 The xNF **MUST** be able to specify the granularity of the
2672 lock via a restricted or full XPath expression.
2674 R-66793 The xNF **MUST** guarantee the xNF configuration integrity
2675 for all simultaneous configuration operations (e.g., if a change is
2676 attempted to the BUM filter rate from multiple interfaces on the same
2677 EVC, then they need to be sequenced in the xNF without locking either
2678 configuration method out).
2680 R-54190 The xNF **MUST** release locks to prevent permanent lock-outs
2681 when/if a session applying the lock is terminated (e.g., SSH session
2684 R-03465 The xNF **MUST** release locks to prevent permanent lock-outs
2685 when the corresponding <partial-unlock> operation succeeds.
2687 R-63935 The xNF **MUST** release locks to prevent permanent lock-outs
2688 when a user configured timer has expired forcing the NETCONF SSH Session
2689 termination (i.e., product must expose a configuration knob for a user
2690 setting of a lock expiration timer)
2692 R-10173 The xNF **MUST** allow another NETCONF session to be able to
2693 initiate the release of the lock by killing the session owning the lock,
2694 using the <kill-session> operation to guard against hung NETCONF sessions.
2696 R-88899 The xNF **MUST** support simultaneous <commit> operations
2697 within the context of this locking requirements framework.
2699 R-07545 The xNF **MUST** support all operations, administration and
2700 management (OAM) functions available from the supplier for xNFs using
2701 the supplied YANG code and associated NETCONF servers.

2711 source pyang [3]_ program using the following commands:
2713 R-63953 The xNF **MUST** have the echo command return a zero value
2714 otherwise the validation has failed
2716 R-26508 The xNF **MUST** support a NETCONF server that can be mounted on
2717 OpenDaylight (client) and perform the operations of: modify, update,
2718 change, rollback configurations using each configuration data element,
2719 query each state (non-configuration) data element, execute each YANG
2720 RPC, and receive data through each notification statement.

2778 RPC executes a xNF Provider-defined xNF HealthCheck over the scope of
2779 the entire xNF (e.g., if there are multiple VNFCs, then run a health check,
2780 as appropriate, for all VNFCs). It returns a 200 OK if the test completes.
2781 A JSON object is returned indicating state (healthy, unhealthy), scope
2782 identifier, time-stamp and one or more blocks containing info and fault
2783 information. If the xNF is unable to run the HealthCheck, return a
2784 standard http error code and message.
2786 R-79224 The xNF **MUST** have the chef-client be preloaded with
2787 validator keys and configuration to register with the designated
2788 Chef Server as part of the installation process.
2790 R-72184 The xNF **MUST** have routable FQDNs for all the endpoints
2791 (VMs) of a xNF that contain chef-clients which are used to register
2792 with the Chef Server. As part of invoking xNF actions, ONAP will
2793 trigger push jobs against FQDNs of endpoints for a xNF, if required.
2795 R-47068 The xNF **MAY** expose a single endpoint that is
2796 responsible for all functionality.
2798 R-67114 The xNF **MUST** be installed with Chef-Client >= 12.0 and
2799 Chef push jobs client >= 2.0.
2801 R-27310 The xNF Package **MUST** include all relevant Chef artifacts
2802 (roles/cookbooks/recipes) required to execute xNF actions requested by
2803 ONAP for loading on appropriate Chef Server.
2805 R-26567 The xNF Package **MUST** include a run list of
2806 roles/cookbooks/recipes, for each supported xNF action, that will
2807 perform the desired xNF action in its entirety as specified by ONAP
2808 (see Section 7.c, ONAP Controller APIs and Behavior, for list of xNF
2809 actions and requirements), when triggered by a chef-client run list
2812 R-98911 The xNF **MUST NOT** use any instance specific parameters
2813 for the xNF in roles/cookbooks/recipes invoked for a xNF action.
2815 R-37929 The xNF **MUST** accept all necessary instance specific
2816 data from the environment or node object attributes for the xNF
2817 in roles/cookbooks/recipes invoked for a xNF action.
2819 R-62170 The xNF **MUST** over-ride any default values for
2820 configurable parameters that can be set by ONAP in the roles,
2821 cookbooks and recipes.
2823 R-78116 The xNF **MUST** update status on the Chef Server
2824 appropriately (e.g., via a fail or raise an exception) if the
2825 chef-client run encounters any critical errors/failures when
2826 executing a xNF action.
2828 R-44013 The xNF **MUST** populate an attribute, defined as node
2829 [‘PushJobOutput’] with the desired output on all nodes in the push job
2830 that execute chef-client run if the xNF action requires the output of a
2831 chef-client run be made available (e.g., get running configuration).
2833 R-30654 The xNF Package **MUST** have appropriate cookbooks that are
2834 designed to automatically ‘rollback’ to the original state in case of
2835 any errors for actions that change state of the xNF (e.g., configure).
2837 R-65755 The xNF **SHOULD** support callback URLs to return information
2838 to ONAP upon completion of the chef-client run for any chef-client run
2839 associated with a xNF action.
2841 R-15885 The xNF **MUST** Upon completion of the chef-client run,
2842 POST back on the callback URL, a JSON object as described in Table
2843 A2 if the chef-client run list includes a cookbook/recipe that is
2844 callback capable. Failure to POST on the Callback Url should not be
2845 considered a critical error. That is, if the chef-client successfully
2846 completes the xNF action, it should reflect this status on the Chef
2847 Server regardless of whether the Callback succeeded or not.
2849 R-32217 The xNF **MUST** have routable FQDNs that are reachable via
2850 the Ansible Server for the endpoints (VMs) of a xNF on which playbooks
2851 will be executed. ONAP will initiate requests to the Ansible Server
2852 for invocation of playbooks against these end points [4]_.
2854 R-54373 The xNF **MUST** have Python >= 2.6 on the endpoint VM(s)
2855 of a xNF on which an Ansible playbook will be executed.
2857 R-35401 The xNF **MUST** support SSH and allow SSH access by the
2858 Ansible server for the endpoint VM(s) and comply with the Network
2859 Cloud Service Provider guidelines for authentication and access.
2861 R-82018 The xNF **MUST** load the Ansible Server SSH public key onto xNF
2862 VM(s) as part of instantiation. This will allow the Ansible Server
2863 to authenticate to perform post-instantiation configuration without
2864 manual intervention and without requiring specific xNF login IDs
2867 R-92866 The xNF **MUST** include as part of post-instantiation configuration
2868 done by Ansible Playbooks the removal/update of the SSH public key from
2869 /root/.ssh/authorized_keys, and update of SSH keys loaded through
2870 instantiation to support Ansible. This may include download and install of
2871 new SSH keys and new mechanized IDs.
2873 R-91745 The xNF **MUST** update the Ansible Server and other entities
2874 storing and using the SSH keys for authentication when the SSH keys used
2875 by Ansible are regenerated/updated.
2877 R-40293 The xNF **MUST** make available playbooks that conform
2878 to the ONAP requirement.
2880 R-49396 The xNF **MUST** support each ONAP (APPC) xNF action by invocation
2881 of **one** playbook [7]_. The playbook will be responsible
2882 for executing all necessary tasks (as well as calling other playbooks)
2883 to complete the request.
2885 R-33280 The xNF **MUST NOT** use any instance specific parameters
2888 R-48698 The xNF **MUST** utilize information from key value pairs
2889 that will be provided by the Ansible Server as "extra-vars" during
2890 invocation to execute the desired xNF action. If the playbook requires
2891 files, they must also be supplied using the methodology detailed in
2892 the Ansible Server API, unless they are bundled with playbooks, example,
2895 R-43253 The xNF **MUST** use playbooks designed to allow Ansible
2896 Server to infer failure or success based on the “PLAY_RECAP” capability.
2897 NOTE: There are cases where playbooks need to interpret results of a task
2898 and then determine success or failure and return result accordingly
2899 (failure for failed tasks).
2901 R-50252 The xNF **MUST** write to a specific one text files that
2902 will be retrieved and made available by the Ansible Server if, as part
2903 of a xNF action (e.g., audit), a playbook is required to return any
2904 xNF information. The text files must be written in the same directory as
2905 the one from which the playbook is being executed. A text file must be
2906 created for the xNF playbook run targets/affects, with the name
2907 ‘<VNFname>_results.txt’ into which any desired output from each
2908 respective VM/xNF must be written.
2910 R-51442 The xNF **SHOULD** use playbooks that are designed to
2911 automatically ‘rollback’ to the original state in case of any errors
2912 for actions that change state of the xNF (e.g., configure).
2914 R-58301 The xNF **SHOULD NOT** use playbooks that make requests to
2915 Cloud resources e.g. Openstack (nova, neutron, glance, heat, etc.);
2916 therefore, there is no use for Cloud specific variables like Openstack
2917 UUIDs in Ansible Playbooks.
2919 R-02651 The xNF **SHOULD** use the Ansible backup feature to save a
2920 copy of configuration files before implementing changes to support
2921 operations such as backing out of software upgrades, configuration
2922 changes or other work as this will help backing out of configuration
2923 changes when needed.
2925 R-43353 The xNF **MUST** return control from Ansible Playbooks only
2926 after tasks are fully complete, signaling that the playbook completed
2927 all tasks. When starting services, return control only after all services
2928 are up. This is critical for workflows where the next steps are dependent
2930 R-51910 The xNF **MUST** provide all telemetry (e.g., fault event
2931 records, syslog records, performance records etc.) to ONAP using the
2932 model, format and mechanisms described in this section.
2934 R-19624 The xNF **MUST** encode and serialize content delivered to
2935 ONAP using JSON (RFC 7159) plain text format. High-volume data is to
2936 be encoded and serialized using `Avro <http://avro.apache.org/>`_,
2937 where the Avro [6]_ data format are described using JSON.
2941 - JSON plain text format is preferred for moderate volume data sets
2942 (option 1), as JSON has the advantage of having well-understood simple
2943 processing and being human-readable without additional decoding. Examples
2944 of moderate volume data sets include the fault alarms and performance
2945 alerts, heartbeat messages, measurements used for xNF scaling and syslogs.
2946 - Binary format using Avro is preferred for high volume data sets
2947 (option 2) such as mobility flow measurements and other high-volume
2948 streaming events (such as mobility signaling events or SIP signaling)
2949 or bulk data, as this will significantly reduce the volume of data
2950 to be transmitted. As of the date of this document, all events are
2951 reported using plain text JSON and REST.
2952 - Avro content is self-documented, using a JSON schema. The JSON schema is
2953 delivered along with the data content
2954 (http://avro.apache.org/docs/current/ ). This means the presence and
2955 position of data fields can be recognized automatically, as well as the
2956 data format, definition and other attributes. Avro content can be
2957 serialized as JSON tagged text or as binary. In binary format, the
2958 JSON schema is included as a separate data block, so the content is
2959 not tagged, further compressing the volume. For streaming data, Avro
2960 will read the schema when the stream is established and apply the
2961 schema to the received content.
2963 R-98191 The xNF **MUST** vary the frequency that asynchronous data is
2964 delivered based on the content and how data may be aggregated or grouped
2969 - For example, alarms and alerts are expected to be delivered as soon
2970 as they appear. In contrast, other content, such as performance
2971 measurements, KPIs or reported network signaling may have various ways
2972 of packaging and delivering content. Some content should be streamed
2973 immediately; or content may be monitored over a time interval, then packaged
2974 as collection of records and delivered as block; or data may be collected
2975 until a package of a certain size has been collected; or content may be
2976 summarized statistically over a time interval, or computed as a KPI, with
2977 the summary or KPI being delivered.
2978 - We expect the reporting frequency to be configurable depending
2979 on the virtual network function’s needs for management. For example,
2980 Service Provider may choose to vary the frequency of collection between
2981 normal and trouble-shooting scenarios.
2982 - Decisions about the frequency of data reporting will affect the
2983 size of delivered data sets, recommended delivery method, and how the
2984 data will be interpreted by ONAP. These considerations should not
2985 affect deserialization and decoding of the data, which will be guided
2986 by the accompanying JSON schema or GPB definition files.
2988 R-88482 The xNF **SHOULD** use REST using HTTPS delivery of plain
2989 text JSON for moderate sized asynchronous data sets, and for high
2990 volume data sets when feasible.
2992 R-84879 The xNF **MUST** have the capability of maintaining a primary
2993 and backup DNS name (URL) for connecting to ONAP collectors, with the
2994 ability to switch between addresses based on conditions defined by policy
2995 such as time-outs, and buffering to store messages until they can be
2996 delivered. At its discretion, the service provider may choose to populate
2997 only one collector address for a xNF. In this case, the network will
2998 promptly resolve connectivity problems caused by a collector or network
2999 failure transparently to the xNF.
3001 R-81777 The xNF **MUST** be configured with initial address(es) to use
3002 at deployment time. Subsequently, address(es) may be changed through
3003 ONAP-defined policies delivered from ONAP to the xNF using PUTs to a
3004 RESTful API, in the same manner that other controls over data reporting
3005 will be controlled by policy.
3007 R-08312 The xNF **MAY** use another option which is expected to include REST
3008 delivery of binary encoded data sets.
3010 R-79412 The xNF **MAY** use another option which is expected to include TCP
3011 for high volume streaming asynchronous data sets and for other high volume
3012 data sets. TCP delivery can be used for either JSON or binary encoded data
3015 R-01033 The xNF **MAY** use another option which is expected to include SFTP
3016 for asynchronous bulk files, such as bulk files that contain large volumes of
3017 data collected over a long time interval or data collected across many xNFs.
3018 (Preferred is to reorganize the data into more frequent or more focused data
3019 sets, and deliver these by REST or TCP as appropriate.)
3021 R-63229 The xNF **MAY** use another option which is expected to include REST
3022 for synchronous data, using RESTCONF (e.g., for xNF state polling).
3024 R-03070 The xNF **MUST**, by ONAP Policy, provide the ONAP addresses
3025 as data destinations for each xNF, and may be changed by Policy while
3026 the xNF is in operation. We expect the xNF to be capable of redirecting
3027 traffic to changed destinations with no loss of data, for example from
3028 one REST URL to another, or from one TCP host and port to another.
3030 R-06924 The xNF **MUST** deliver asynchronous data as data becomes
3031 available, or according to the configured frequency.
3033 R-73285 The xNF **MUST** must encode, address and deliver the data
3034 as described in the previous paragraphs.
3036 R-42140 The xNF **MUST** respond to data requests from ONAP as soon
3037 as those requests are received, as a synchronous response.
3039 R-34660 The xNF **MUST** use the RESTCONF/NETCONF framework used by
3040 the ONAP configuration subsystem for synchronous communication.
3042 R-86586 The xNF **MUST** use the YANG configuration models and RESTCONF
3043 [RFC8040] (https://tools.ietf.org/html/rfc8040).
3045 R-11240 The xNF **MUST** respond with content encoded in JSON, as
3046 described in the RESTCONF specification. This way the encoding of a
3047 synchronous communication will be consistent with Avro.
3049 R-70266 The xNF **MUST** respond to an ONAP request to deliver the
3050 current data for any of the record types defined in
3051 Event Records - Data Structure Description by returning the requested
3052 record, populated with the current field values. (Currently the defined
3053 record types include fault fields, mobile flow fields, measurements for
3054 xNF scaling fields, and syslog fields. Other record types will be added
3055 in the future as they become standardized and are made available.)
3057 R-46290 The xNF **MUST** respond to an ONAP request to deliver granular
3058 data on device or subsystem status or performance, referencing the YANG
3059 configuration model for the xNF by returning the requested data elements.
3061 R-43327 The xNF **SHOULD** use `Modeling JSON text with YANG
3062 <https://tools.ietf.org/html/rfc7951>`_, If YANG models need to be
3063 translated to and from JSON[RFC7951]. YANG configuration and content can
3064 be represented via JSON, consistent with Avro, as described in “Encoding
3065 and Serialization” section.
3067 R-42366 The xNF **MUST** support secure connections and transports such as
3068 Transport Layer Security (TLS) protocol
3069 [`RFC5246 <https://tools.ietf.org/html/rfc5246>`_] and should adhere to
3070 the best current practices outlined in
3071 `RFC7525 <https://tools.ietf.org/html/rfc7525>`_.
3073 R-44290 The xNF **MUST** control access to ONAP and to xNFs, and creation
3074 of connections, through secure credentials, log-on and exchange mechanisms.
3076 R-47597 The xNF **MUST** carry data in motion only over secure connections.
3078 R-68165 The xNF **MUST** encrypt any content containing Sensitive Personal
3079 Information (SPI) or certain proprietary data, in addition to applying the
3080 regular procedures for securing access and delivery.
3083 Ansible Playbook Examples
3084 -----------------------------------------------
3086 The following sections contain examples of Ansible playbooks
3087 which follow the guidelines.
3089 Guidelines for Playbooks to properly integrate with APPC
3090 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3092 NOTE: To support concurrent requests to multiple VNF instances of same
3093 or different type, VNF hosts and other files with VNF specific default
3094 values are kept or created in separate directories.
3096 Example of an Ansible command (after pwd) to run playbook again
3097 vfdb9904v VNF instance:
3099 .. code-block:: none
3102 /storage/vfdb/V16.1/ansible/configure
3103 $ ansible-playbook -i ../inventory/vfdb9904vhosts site.yml --extra-vars "vnf_instance=vfdb9904v"
3105 NOTE: To preserve Ansible inventory/group_vars capability, that makes
3106 group_vars contents global variables available to all playbooks, when they
3107 reside in the inventory directory, guidelines are being updated to name the
3108 VNF inventory hosts file as (a flat file) <VNFName>hosts, stored in the
3109 inventory directory, not a subdirectory under inventory. In the above
3110 example: vfdb9904vhosts (removed / VNF name and hosts vfdb9904/vhosts)
3112 Example of corresponding APPC API Call from ONAP – Ansible Server
3115 An example of a curl request simulating a Rest API POST requesting execution
3116 of configure Playbook (using playbook relative path):
3118 .. code-block:: none
3120 curl -u APIUser:APIPassword -H "Content-type:application/json" -X POST
3121 -d '{"Id": "8412", "PlaybookName": "vfdb/V5.x.x/ansible/configure/site.yml",
3122 "Timeout":"600", "EnvParameters": { "vnf_instance": "vfdb9904v" }}'
3123 http://ansible.server.com:5000/Dispatch
3125 Rest API GET request to obtain response/results for prior request
3126 (same Id as POST request above):
3128 .. code-block:: none
3130 curl -u APIUser:APIPassword -H 'Content-type: application/json' -X GET
3131 'http://ansible.server.com:5000/Dispatch/?Id=8412&Type=GetResult'
3135 - An ID number is assigned to each request. This ID number is used to
3136 track request down to completion and provide status to APPC when
3139 - Playbook Name relative path provided in the request as PlaybookName
3141 - Ansible Server Rest API is aware of playbook’s root directory which may
3142 vary from instance to instance or Ansible Server cluster to cluster.
3144 Ansible Playbooks will use the VNF instance name (passed using
3145 --extra-vars "vnf\_instance=vfdb9904v") to identify other default values
3146 to run the playbook(s) against the target VNF instance. Same example as
3149 .. code-block:: none
3151 $ ansible-playbook -i ../inventory/vfdb9904vhosts site.yml --extra-vars "vnf_instance=vfdb9904v"
3153 Each Ansible Server or cluster is assigned its own identification to be used
3154 to authenticate to VNF VMs using Ansible Server or cluster specific set of
3155 SSH keys that may be rotated regularly. Here hosts file, no longer referencing
3156 file with SSH key credentials, to run ansible-playbook listed in this example
3157 above (IP addresses were scrubbed):
3159 .. code-block:: none
3161 $ more ../inventory/vfdb9904v/hosts
3163 localhost ansible_connection=local
3173 NOTE: APPC requests to run Playbooks/Cookbooks are specific to a VNF,
3174 but could be more limited to one VM or one type of VM by the request
3175 parameters. Actions that may impact a site (LCP), a service, or an
3176 entire platform must be orchestrated by MSO in order to execute requests
3177 via APPC which then invoke VNF level playbooks. Playbooks that impact
3178 more than a single VNF are not the current focus of these guidelines.
3180 Since last release of these guidelines, based on recent learnings,
3181 moving VNF Type global variables under inventory/group_vars files, this
3182 way variables and respective values are available to all playbooks without
3183 being explicitly referenced though an include statement. Also creating
3184 templates that are VNF Type specific, but moving away from static files
3185 that are VNF instance specific, working to obtain VNF instance specific
3186 from other sources, inventory database, etc.
3188 And here the scrubbed default arguments for this VNF instance(originated
3189 from previously re-factored playbooks now being phased out):
3191 .. code-block:: none
3193 vnf_instance=vfdb9904v
3195 $ more ../vars/vfdb9904v/default_args.yml
3196 vm_config_oam_vnfc_name: vfdb9904vm001oam001
3197 vm_config_oam_hostname: vfdb9904vm001
3198 vm_config_oam_provider_ip_address: 1xx.2yy.zzz.109
3201 IMPORTANT: The APPC and default file attribute name for
3202 vm\_config\_oam\_vnfc\_name, as an example, is derived from vm\_config
3203 array structure (list) in the CSAR package ENV file, with dots replaced
3206 .. code-block:: none
3210 oam: {vnfc_name: {{ vm_config_oam_vnfc_name }}, hostname: {{
3211 vm_config_oam_hostname }}, provider_ip_address: {{
3212 vm_config_oam_provider_ip_address }
3216 Parameters like VNF names, VNFC names, OA&M IP addresses, after
3217 February, 2018 ONAP release, will be extracted from A&AI by APPC and
3218 then passed down to Ansible Server, as part of APPC request through REST
3219 API. In the meantime, VNF instance specific required values, will
3220 be stored on VNF instance directory, default arguments file and will be
3221 used as defaults. For parameterized playbooks attribute-value pairs
3222 passed down by APPC to Ansible Server always take precedence over
3223 template or VNF instance specific defaults stored in defaults file(s).
3225 .. code-block:: none
3228 /storage/vfdb/latest/ansible
3229 Again, originated from previously re-factored playbooks now being phased out:
3231 $ more vars/vfdb9904v/default_args.yml
3233 vm_config_oam1_vnfc_name: vfdb9904vm001oam001
3234 vm_config_oam1_hostname: vfdb9904vm001
3235 vm_config_oam1_provider_ip_address: 1xx.2yy.zzz.109
3237 vm_config_oam2_vnfc_name: vfdb9904vm002oam001
3238 vm_config_oam2_hostname: vfdb9904vm002
3239 vm_config_oam2_provider_ip_address: 1xx.2yy.zzz.110
3241 vm_config_rdb1_vnfc_name: vfdb9904vm003rdb001
3242 vm_config_rdb1_hostname: vfdb9904vm003
3243 vm_config_rdb1_provider_ip_address: 1xx.2yy.zzz.105
3245 vm_config_rdb2_vnfc_name: vfdb9904vm004rdb001
3246 vm_config_rdb2_hostname: vfdb9904vm004
3247 vm_config_rdb2_provider_ip_address: 1xx.2yy.zzz.106
3249 vm_config_rdb3_vnfc_name: vfdb9904vm005rdb001
3250 vm_config_rdb3_hostname: vfdb9904vm005
3251 vm_config_rdb3_provider_ip_address: 1xx.2yy.zzz.xxx
3253 vm_config_rdb4_vnfc_name: vfdb9904vm006rdb001
3254 vm_config_rdb4_hostname: vfdb9904vm006
3255 vm_config_rdb4_provider_ip_address: 1xx.2yy.zzz.yyy
3257 One of the first tasks on the Ansible Playbooks is to combine the VNF
3258 type generic template, derived from ENV files in CSAR or other files,
3259 with these default values stored on the Ansible Server, together with
3260 the overriding parameters passed down from APPC, to create the VNF
3261 instance specific set of attribute-value pairs to be used for the run, in
3262 INI format. Here is an excerpt from such a file that should look
3263 somewhat similar to ENV files:
3265 .. code-block:: none
3267 $ more tmp/vfdb9904v/all.yml
3269 deployment_prefix: vfdb9904v
3273 template_version: '2014-10-16'
3274 stack_name: vfdb9904v
3276 stackName: vfdb9904v
3280 # logins list contain 'login name', 'login group', 'login password'
3282 .. code-block:: none
3285 - { name: 'm99999', group: 'm99999', password: 'abcdefgha' }

3287 - { name: 'peruser', group: 'peruser', password: ' abcdefgha' }
3288 - { name: 'dbuser', group: 'dbuser', password: ' abcdefgha' }
3290 NOTE: Arguments passed by APPC to Ansible Server to run a playbook take
3291 precedence over any defaults stored in Ansible Server.
3293 Ansible Playbooks – Notes On Artifacts Required to Run Playbooks
3294 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3296 Inventory hosts file: should be VNF instance specific.
3298 Default variables: should be VNF instance specific.
3300 NOTE: Some playbooks may rely on inventory directory contents to target
3301 the collection of VNFs in the Services Platform supported through
3304 Playbooks and paths to referenced files: Playbooks shall not use
3305 absolute paths in include or import entries (variables or playbooks) or
3306 other types of references.
3308 For this to work properly, when running playbooks, the directory where
3309 the main playbook resides shall be the current directory.
3311 Playbook imports, when used, shall use paths relative to the main
3314 Root directory named ansible - Any files provided with playbooks,
3315 included, imported, or referenced by playbooks, shall reside under the ansible
3316 playbooks (root) directory, containing all playbook subdirectories, or
3317 below that ansible root directory, in other subdirectories to support
3318 on-boarding and portability of VNF collection of playbooks and related
3321 Designing for a shared environment, concurrently running playbooks,
3322 targeting multiple VNF instances – inventory hosts file:
3324 To avoid inventory hosts file overwrites or collisions between multiple
3325 concurrently running VNF instance requests, chosen approach is for each
3326 VNF instance hosts file, to be stored under the Ansible Server Playbooks
3327 root directory, under the inventory subdirectory, and under a directory
3328 for each VNF instance, named after the VNF instance, as follows:
3330 ansible/inventory/<VNF\_instance\_name>/hosts
3332 Example of inventory hosts file path, relative to ansible playbooks root
3333 directory (playbooks\_dir): ansible/inventory/vnfx0001v/hosts
3335 **Designing for a shared environment, concurrently running multiple playbooks,
3336 targeting multiple VNF instances – default argument variables for
3337 specific VNF instances:**
3339 Files containing attribute name value pairs (variable name and default
3340 values), referenced/included by playbooks – Files containing VNF
3341 instance specific default values – in a later APPC release, some or all
3342 the default attribute value pairs contained in the defaults file, may be
3343 passed down by APPC, to the Ansible Server, overriding these defaults:
3345 VNF instance specific files
3346 referenced/included by playbooks, containing default values, example,
3347 default\_args.yml, shall be stored under a directory with VNF instance
3352 ansible/vars/<VNF\_instance\_name>/default\_args.yml
3354 Example of include statement:
3356 - include_vars: ../vars/{{ vnf_instance }}/default_args.yml
3358 Again, this was originated from previously re-factored playbooks, now being
3359 phased out, to move away from having to create VNF instance specific files
3360 with VNF instance default variables. Moving to extract these values from
3361 inventory databases and provide them to Ansible Server as part of the APPC
3362 request, but may be used in a transition from having everything stored in the
3363 Ansible Server to APPC extracting and providing VNF instance specific
3364 attribute-value pairs to the Ansible Server as part of the request.
3366 Files containing attribute name value pairs (variable name and default
3367 values), referenced/included by playbooks – created dynamically by
3371 overwrites or collisions of multiple concurrently running VNF instance
3372 requests, files created dynamically by playbooks, based on VNF generic
3373 templates, combined with default values and arguments passed down by
3374 APPC (as part of the request), shall be stored under a directory with
3375 VNF instance name on the path.
3379 tmp/<VNF\_instance\_name>/all.yml
3381 Files containing site specific (Openstack location non-instance
3382 specific) attribute name value pairs, like NTP server and DNS server’s
3383 IP addresses and other parameters, referenced/included by playbooks, not
3384 VNF specific – Could/should be stored under inventory/group_vars directory,
3385 in a subdirectory named after the string used to identify the site (nyc1,
3390 ansible/inventory/group_vars/<Site>
3392 ansible/inventory/group_vars/nyc1
3394 ansible/inventory/group_vars/lax2
3397 \ **Ansible Server Design - Directory Structure**
3399 To help understanding the contents of this section, here are few basic
3402 **VNF type a.k.a VNF Function Code** - Based on current Services
3403 Platform naming convention, each Virtual Network Function is assigned a
3404 4 character string (example vfdb), these are 4 characters in
3405 the VNF instance name, followed by (4) numbers, ending in a "v", but the
3406 naming convention is evolving. VNF instance name in
3407 some cases corresponds to the stack name for the VNF when VNF instance
3408 is built based on a single module, single stack. Example of VNF instance
3409 name: vfdb9904v. All VNF performing this function, running the same
3410 software, coming from the same VNF provider will have the same 4
3411 characters in the VNF instance name, in this example, vfdb.
3413 NOTE: New naming convention includes a prefix indicating geographical
3414 location where VNF is instantiated.
3416 VNF type, determined through these 4 characters, is also known as VNF
3417 Function Code and is assigned by inventory team. All Services Platform
3418 VNF Function Codes can be found in inventory database and/or A&AI as
3419 well as Services Platform Network Design Documents.
3421 Version – As in VNF software version is the release of the software
3422 running on the VNF for which the playbooks were developed. VNF
3423 configuration steps may change from release to release and this
3424 <Version> in the path will allow the Ansible Server to host playbooks
3425 associated with each software release. And run the playbooks that match
3426 the software release running on each VNF instance. APPC initially will
3427 not support playbook versioning only latest playbook is supported or a hard
3428 coded version that later should become a variable to allow multiple
3429 actively in use playbook versions according to VNF release.
3431 Playbook Function - Is a name associated with a life cycle management
3432 task(s) performed by the playbook(s) stored in this directory. It should
3433 clearly identify the type of action(s) performed by the main playbook
3434 and possibly other playbooks stored in this same directory. Ideally,
3435 playbook function would match APPC corresponding command or function that
3436 is performed by the main playbook in this directory. Following Ansible naming
3437 standards main playbook is usually named site.yml. There can be other
3438 playbooks on the same directory that use a subset of the roles used by the
3439 main playbook site.yml. Examples of Playbook Function directory names:
3441 - configure – Contains post-instantiation (bulk) configuration
3444 - healthcheck – Contains VNF health check playbook(s), roles,…
3446 - stop – Contains VNF application stop (stopApplication) playbook(s),
3449 - start – Contains VNF application start (startApplication) playbook(s),
3452 Directory structure to allow hosting multiple version sets of playbooks,
3453 for the same VNF type, to be hosted in the runtime environment on the
3454 Ansible Servers. Generic directory structure:
3456 Ansible Playbooks – Function directory and main playbook:
3458 .. code-block:: none
3460 <VNF type>/<Version>/ansible/<Playbook Function>/site.yml
3462 Example – Post-instantiation (bulk) configuration –APPC Function -
3465 .. code-block:: none
3467 <VNF type>/<Version>/ansible/configure/site.yml
3469 Example – Post-instantiation (bulk) configuration –APPC Function
3470 – Configure – VNF software version 16.1:
3472 .. code-block:: none
3474 vfdb/V16.1/ansible/configure/site.yml
3476 Example – Health-check –APPC Function - HealthCheck:
3478 .. code-block:: none
3480 <VNF type>/<Version>/ansible/healthcheck/site.yml
3482 OR (Function directory name does not need to match APPC function name)
3484 .. code-block:: none
3486 <VNF type>/<Version>/ansible/check/site.yml
3488 Ansible Directories for other artifacts – VNF inventory hosts file -
3491 .. code-block:: none
3493 <VNF type>/<Version>/ansible/inventory/<VNF instance name>hosts
3495 Ansible Directories for other artifacts – VNF instance specific default
3496 arguments – Optional:
3498 .. code-block:: none
3500 <VNF type>/<Version>/ansible/group_vars/<VNF instance name>
3502 NOTE: This requirement is expected to be deprecated all or in part in the
3503 future, for automated actions, once APPC can pass down all VNF specific
3504 arguments for each action. Requirement remains while manual actions are
3505 to be supported. Other automated inventory management mechanisms may be
3506 considered in the future, Ansible supports many automated inventory
3507 management mechanisms/tools/solutions.
3509 Ansible Directories for other artifacts – VNF (special) groups –
3512 .. code-block:: none
3514 <VNF type>/<Version>/ansible/inventory/group_vars/<VNF instance name>
3516 NOTE: Default groups will be created based on VNFC type, 3 characters,
3517 on VNFC name. Example: “oam”, “rdb”, “dbs”, “man”, “iox”, “app”,…
3519 Ansible Directories for other artifacts – VNF (special) other files –
3520 Optional – Example – License file:
3522 .. code-block:: none
3524 <VNF type>/<Version>/ansible/<Other directory(s)>
3526 CAUTION: On referenced files used/required by playbooks.
3528 - To avoid missing files, during on-boarding or uploading of Ansible
3529 Playbooks and related artifacts, all permanent files (not generated
3530 by playbooks as part of execution), required to run any playbook,
3531 shall reside under the ansible root directory or below on other
3534 - Any references to files, on includes or other playbook entries, shall
3537 - This is the ansible (root) directory referenced on this
3538 note (Ansible Server mount point not included):
3540 .. code-block:: none
3542 <VNF type>/<Version>/ansible/
3544 There will be a soft link to the latest set of Ansible Playbooks for
3547 VNF type directories use A&AI inventory VNF function code. Ansible
3548 Playbooks will be stored on a Cinder Volume mounted on the Ansible
3549 Servers as /storage. Example:
3551 /storage/vfdb/latest/ansible – This soft link point to the latest set of
3552 playbooks (or the only set)
3554 /storage/vfdb/V16.1/ansible – Root directory for database VNF Ansible
3555 Playbooks for release 16.1
3557 CAUTION: To support this directory structure as the repository to store
3558 Ansible Playbooks run by APPC, APPC API in the Ansible Server side needs
3559 to be configured to run playbooks from directory, not MySQL database.
3561 Ansible Server HTTP will be configured to support APPC REST API requests
3562 to run playbooks as needed, against specific VNF instances, or specific
3563 VM(s) as specified in the request.
3565 ONAP APPC REST API to Ansible Server is documented separately and can be
3566 found under ONAP (onap.org).
3568 **Ansible Server – On-boarding Ansible Playbooks**
3570 Once playbooks are developed following the guidelines listed in prior
3571 section(s), playbooks need to be on-boarded onto Ansible Server(s). In
3572 the future, they’ll be on-boarded and distributed through ONAP, at least
3573 that is the proposed plan, but for now they need to be uploaded
3574 manually. There is work in progress to use a Git as the playbook
3575 repository to store and track playbooks by version, version control.
3577 These are the basic steps to on-board playbooks manually onto the
3580 1. Upload CSAR, zip, or tar file containing VNF playbooks and related
3583 2. Create full directory (using –p option below) to store Ansible
3584 Playbooks and other artifacts under /storage (or other configured)
3587 a. Includes VNF type using VNF function code 4 characters under
3590 b. Includes VNF “Version” directory as part of the path to store
3591 playbooks for this VNF version.
3593 c. Include generic ansible root directory. Creating full directory
3596 .. code-block:: none
3598 $ mkdir –p /storage/vfdb/V16.1/ansible**/**
3600 3. Make this directory (VNF ansible root directory) current directory
3603 .. code-block:: none
3605 cd /storage/vfdb/V16.1/ansible/
3607 4. Extract Ansible Playbooks and other Ansible artifacts associated with
3608 the playbooks onto the ansible directory. Command depends on the type
3609 of file uploaded, examples would be:
3611 .. code-block:: none
3617 5. Create VNF inventory hosts file with all VMs and
3618 OA&M IP addresses for all VNF instances with known OA&M IP addresses
3619 for respective VMs, example:
3621 .. code-block:: none
3625 $ touch inventory/vfdb9904vhosts
3627 $ cat inventory/vfdb9904vhosts
3630 localhost ansible\_connection=local
3640 6. (Optional, being deprecated) Create directory to hold default
3641 arguments for each VNF instance,
3644 .. code-block:: none
3646 $ mkdir –p vars/vfdb9904v
3647 $ touch vars/vfdb9904v/default\_args.yml
3648 $ cat vars/vfdb9904v/default\_args.yml
3649 vm\_config\_oam1\_vnfc\_name: vfdb9904vm001oam001
3650 vm\_config\_oam1\_hostname: vfdb9904vm001
3651 vm\_config\_oam1\_provider\_ip\_address: 1xx.2yy.zzz.109
3653 vm\_config\_oam2\_vnfc\_name: vfdb9904vm002oam001
3654 vm\_config\_oam2\_hostname: vfdb9904vm002
3655 vm\_config\_oam2\_provider\_ip\_address: 1xx.2yy.zzz.110
3657 vm\_config\_rdb1\_vnfc\_name: vfdb9904vm003rdb001
3658 vm\_config\_rdb1\_hostname: vfdb9904vm003
3659 vm\_config\_rdb1\_provider\_ip\_address: 1xx.2yy.zzz.105
3661 vm\_config\_rdb2\_vnfc\_name: vfdb9904vm004rdb001
3662 vm\_config\_rdb2\_hostname: vfdb9904vm004
3663 vm\_config\_rdb2\_provider\_ip\_address: 1xx.2yy.zzz.106
3665 vm\_config\_rdb3\_vnfc\_name: vfdb9904vm005rdb001
3666 vm\_config\_rdb3\_hostname: vfdb9904vm005
3667 vm\_config\_rdb3\_provider\_ip\_address: 1xx.2yy.zzz.xxx
3669 vm\_config\_rdb4\_vnfc\_name: vfdb9904vm006rdb001
3670 vm\_config\_rdb4\_hostname: vfdb9904vm006
3671 vm\_config\_rdb4\_provider\_ip\_address: 1xx.2yy.zzz.yyy
3673 NOTE: Please note names in this file shall use underscore “\_” not dots
3676 7. Perform some basic playbook validation running with “--check” option,
3677 running dummy playbooks or other.
3679 NOTE: Each Ansible Server or cluster of Ansible Server will have its own
3680 credentials to authenticate to VNF VMs. Ansible Server SSH public key(s)
3681 have to be loaded onto VNF VMs during instantiation or other way before
3682 Ansible Server can access VNF VMs and run playbooks. HOT templates used
3683 by heat to instantiate VNFs to be configured by these Ansible Servers running
3684 playbooks shall include the same SSH public key and load them onto VNF VM(s)
3685 as part of instantiation.
3687 Other non-vendor specific playbook tasks need to be incorporated in overall
3688 post-instantiation configuration playbook. Alternative is for company
3689 developed playbooks to be uploaded and executed, after VNF vendor provided
