  22 APPC LCM API Guide
  23 ==================
  24
  25 Introduction
  26 ============
  27
  28 This guide describes the APPC API that allows you to manage and control the life cycle of controlled virtual network functions (VNFs).
  29
  30
  31 Target Audience
  32 ---------------
  33 This document is intended for an advanced technical audience, such as the engineers or architects who need to use this guide to develop an interfacing application. The guide assumes a knowledge of the Open Network Automation Platform (ONAP) components and features, and familiarity with JSON notation.
  34
  35
  36 Life Cycle Management Commands
  37 ==============================
  38
  39 APPC receives commands from external ONAP components, such as SO, Policy, DCAE, or the Portal, to manage the life cycle of virtual applications and their components.
  40
  41 A virtual application is composed of the following layers of network technology:
  42
  43 - Virtual Network Function (VNF)
  44 - Virtual Network Function Component (VNFC)
  45 - Virtual Machine (VM)
  46
  47 A Life Cycle Management (LCM) command may affect one or more of these layers.
  48
  49 An LCM command is sent as a request to the APPC using an HTTP POST request or in a message on a message bus (DMaaP or UEB).  A request may result in either a single synchronous response or multiple asynchronous responses:
  50
  51 - An **asynchronous** command, which is sent as an authorized and valid request, results in at least two discrete response events:
  52     - an accept response, to indicate that the request is accepted for processing
  53     - a final response to indicate the status and outcome of the request processing
  54     - An unauthorized or invalid request results in a single ERROR response.
  55
  56 - A **synchronous** command, such as Lock or Unlock, results in a single response that is either SUCCESS or ERROR.
  57
  58 **NOTE:** For both asynchronous or synchronous commands, the first response is always returned using the same transport that the initial action used. For example, if the action request was via the message bus (such as when it originates from Policy), then the response is also via the message bus. However, if the request was via a direct HTTP call, the response is similarly a synchronous HTTP response.
  59
  60
  61 Message Bus and the LCM API Client Library
  62 ------------------------------------------
  63
  64 The recommended approach for sending/receiving requests to APPC is via the message bus.   To support this approach, an APPC client library is available and should be used.  The client library aims to provide consumers of APPC capabilities with a strongly-typed Java interface and to encapsulate the actual interaction with APPC component via the message bus.
  65
  66 For more details, see the APPC Client Library Guide at:
  67
  68   :ref:`appc_client_library`
  69
  70
  71 The client library supports both synchronous and asynchronous flows as follows.
  72
  73 Asynchronous Flow
  74 ^^^^^^^^^^^^^^^^^
  75
  76 - The APPC Client Library is called via an asynchronous API using a full command object, which is mapped to a JSON representation.
  77 - The APPC client calls the UEB/DMaaP client and sends the JSON command to a configured topic.
  78 - The APPC client pulls response messages from the configured topic.
  79 - On receiving the response for the command, APPC client runs the relevant callback method of the consumer ResponseHandler.
  80
  81 Synchronous Flow
  82 ^^^^^^^^^^^^^^^^
  83
  84 - The APPC Client Library is called via a synchronous API using a full command object, which is mapped to a JSON representation.
  85 - The APPC client calls the UEB/DMaaP client and sends the JSON command to a configured topic.
  86 - The APPC client pulls response messages from the configured topic.
  87 - On receiving the final response for the command, the APPC client returns the response object with a final status.
  88
  89 The client library adds the following wrapper around request and responses to the LCM API (described below)::
  90
  91     {
  92         "version" : "2.0",
  93         "cambria.partition" : "<TOPIC>",
  94         "correlation-id" :"<CORRELATION_ID>",
  95         "rpc-name" : "<RPC_NME>",
  96         "type" : <MESSAGE_TYPE>
  97         "body" : <RPC_SPECIFIC_BODY>
  98     }

 556 Self-Service VNF Onboarding
 557 ---------------------------
 558
 559 The APPC architecture is designed for VNF self-service onboarding (i.e., a VNF owner or vendor through the use of tools can enable a new VNF to support the LCM API actions that are designate as self-service). The VNF must support one or more of the following interface protocols:
 560
 561 -  Netconf with uploadable Yang model (requires a Netconf server running
 562    on the VNF)
 563
 564 -  Chef (requires a Chef client running on the VNF)
 565
 566 -  Ansible (does not require any changes to the VNF software)
 567
 568 The self-service onboarding process is done using an APPC Design GUI which interacts with an APPC instance which is dedicated to self-service onboarding. The steps in the onboarding process using the APPC Design GUI are:
 569
 570 -  Define the VNF capabilities (set of actions that the VNF can
 571    support).
 572
 573 -  Create a template and parameter definitions for actions which use the
 574    Netconf, Chef, or Ansible protocols. The template is an xml or JSON
 575    block which defines the “payload” which is included in the request
 576    that is downloaded the VNF (if Netconf) or Chef/Ansible server.
 577
 578 -  Test actions which have templates/parameter definitions.
 579
 580 -  Upload the VNF definition, template, and parameter definition
 581    artifacts to SDC which distributes them to all APPC instances in the
 582    same environment (e.g., production).
 583

 588 LCM Commands
 589 ============
 590
 591 The LCM commands that are valid for the current release.
 592
 593
 594 Audit
 595 -----
 596
 597 The Audit command compares the configuration of the VNF associated with the current request against the most recent configuration that is stored in APPC's configuration database.
 598
 599 A successful Audit means that the current VNF configuration matches the latest APPC stored configuration.
 600
 601 A failed Audit indicates that the configurations do not match.
 602
 603 This command can be applied to any VNF type. The only restriction is that the VNF has been onboarded in self-service mode (which requires that the VNF supports a request to return the running configuration).
 604
 605 The Audit action does not require any payload parameters.
 606
 607 **NOTE:** Audit does not return a payload containing details of the comparison, only the Success/Failure status.

 639 The audit response returns an indication of success or failure of the audit. If a new configuration is uploaded to the APPC database, the payload contains the ‘upload\_config\_id’ and values for any records created. In addition, the configuration is sent to the ONAP Data Router bus which may be received by an external configuration storage system.
 640
 641
 642 CheckLock
 643 ---------
 644
 645 The CheckLock command returns true if the specified VNF is locked; otherwise, false is returned.
 646
 647 A CheckLock command is deemed successful if the processing completes without error, whether the VNF is locked or not. The command returns only a single response with a final status.
 648
 649 Note that APPC locks the target VNF during any VNF command processing, so a VNF can have a locked status even if no Lock command has been explicitly called.
 650
 651 The CheckLock command returns a specific response structure that extends the default LCM response.
 652
 653 The CheckLock action does not require any payload parameters.

 908
 909 Evacuate
 910 --------
 911
 912 Evacuates a specified VM from its current host to another. After a successful evacuate, a rebuild VM is performed if a snapshot is available (and the VM boots from a snapshot.
 913
 914 The host on which the VM resides needs to be down.
 915
 916 If the node is not specified in the request, it will be selected by relying on internal rules to evacuate. The Evacuate action will fail if the specified target host is not UP/ENABLED.
 917
 918 After Evacuate, the rebuild VM can be disabled by setting the optional `rebuild-vm <#_bookmark43>`__ parameter to false.
 919
 920 A successful Evacuate action returns a success response. A failed Evacuate action returns a failure.

 975 A health check is VNF-specific. For a complex VNF, APPC initiates further subordinate health checks.
 976
 977 HealthCheck is a VNF level command which interrogates the VNF in order to determine the health of the VNF and the VNFCs. The HealthCheck will be implemented differently for each VNF.

1004 Lock
1005 ----
1006
1007 Use the Lock command to ensure exclusive access during a series of critical LCM commands.
1008
1009 The Lock action will return a successful result if the VNF is not already locked or if it was locked with the same request-id, otherwise the action returns a response with a reject status code.
1010
1011 Lock is a command intended for APPC and does not execute an actual VNF command. Instead, lock will ensure that ONAP is granted exclusive access to the VNF.
1012
1013 When a VNF is locked, any subsequent sequential commands with same request-id will be accepted. Commands associated with other request-ids will be rejected.
1014
1015 The Lock command returns only one final response with the status of the request processing.
1016
1017 APPC locks the target VNF during any VNF command processing. If a lock action is then requested on that VNF, it will be rejected because the VNF was already locked, even though no actual lock command was explicitly invoked.

1031 Migrate
1032 -------
1033
1034 Migrates a running target VM from its current host to another.
1035
1036 A destination node will be selected by relying on internal rules to migrate. Migrate calls a command in order to perform the operation.
1037
1038 Migrate suspends the guest virtual machine, and moves an image of the guest virtual machine's disk to the destination host physical machine. The guest virtual machine is then resumed on the destination host physical machine and the disk storage that it used on the source host physical machine is freed.
1039
1040 The migrate action will leave the VM in the same Openstack state the VM had been in prior to the migrate action. If a VM was stopped before migration, a separate VM-level restart command would be needed to restart the VM after migration.
1041
1042 A successful Migrate action returns a success response and the new node identity in the response payload block.
1043
1044 A failed Migrate action returns a failure and the failure messages in the response payload block.
1045
1046 **NOTE:** The command implementation is based on Openstack functionality. For further details, see http://developer.openstack.org/api-ref/compute/.

1079 Rebuild
1080 -------
1081
1082 Recreates a target VM instance to a known, stable state.
1083
1084 Rebuild calls an OpenStack command immediately and therefore does not expect any prerequisite operations to be performed, such as shutting off a VM.
1085
1086 APPC only supports the rebuild operation for a VM that boots from image (snapshot), i.e., APPC rejects a rebuild request if it determines the VM boots from volume (disk).
1087
1088 A successful rebuild returns a success response and the rebuild details in the response payload block. A failed rebuild returns a failure and the failure messages in the response payload block.
1089

1104 Restart
1105 -------
1106
1107 Use the Restart command to restart a VNF or a single VM. The generic VNF Restart uses a simple restart logic where all VM’s are stopped and re-started.
1108
1109 The generic Restart operation is invoked either for the VM or the VNF level.

1338 StopApplication Response
1339 ^^^^^^^^^^^^^^^^^^^^^^^^
1340
1341 The StopApplication response returns an indication of success or failure of the request.
1342
1343 Sync
1344 ----
1345
1346 The Sync action updates the current configuration in the APPC store with the running configuration from the device.
1347
1348 A successful Sync returns a success status.
1349
1350 A failed Sync returns a failure response status and failure messages in the response payload block.
1351
1352 This command can be applied to any VNF type. The only restriction is that the VNF has been onboarded in self-service mode (which requires that the VNF supports a request to return the running configuration).

1366 Unlock
1367 ------
1368
1369 Run the Unlock command to release the lock on a VNF and allow other clients to perform LCM commands on that VNF.
1370
1371 Unlock is a command intended for APPC and does not execute an actual VNF command. Instead, unlock will release the VNF from the exclusive access held by the specific request-id allowing other requests for the VNF to be accepted.
1372
1373 The Unlock command will result in success if the VNF successfully unlocked or if it was already unlocked, otherwise commands will be rejected.
1374
1375 The Unlock command will only return success if the VNF was locked with same `request-id <#_bookmark4>`__.
1376
1377 The Unlock command returns only one final response with the status of the request processing.
1378
1379 Note: APPC locks the target VNF during any command processing. If an Unlock action is then requested on that VNF with a different request-id, it will be rejected because the VNF is already locked for another process, even though no actual lock command was explicitly invoked.
