In the above + example: vfdb9904vhosts (removed / VNF name and hosts vfdb9904/vhosts) + +Example of corresponding APPC API Call from ONAP – Ansible Server +Specifications: + +An example of a curl request simulating a Rest API POST requesting execution +of configure Playbook (using playbook relative path): + +.. code-block:: none + + curl -u APIUser:APIPassword -H "Content-type:application/json" -X POST + -d '{"Id": "8412", "PlaybookName": "vfdb/V5.x.x/ansible/configure/site.yml", + "Timeout":"600", "EnvParameters": { "vnf_instance": "vfdb9904v" }}' + http://ansible.server.com:5000/Dispatch + +Rest API GET request to obtain response/results for prior request +(same Id as POST request above): + +.. code-block:: none + + curl -u APIUser:APIPassword -H 'Content-type: application/json' -X GET + 'http://ansible.server.com:5000/Dispatch/?Id=8412&Type=GetResult' + +Comments: + +- An ID number is assigned to each request.

Same example as +above: + +.. code-block:: none + + $ ansible-playbook -i ../inventory/vfdb9904vhosts site.yml --extra-vars "vnf_instance=vfdb9904v" + +Each Ansible Server or cluster is assigned its own identification to be used +to authenticate to VNF VMs using Ansible Server or cluster specific set of +SSH keys that may be rotated regularly.

Actions that may impact a site (LCP), a service, or an +entire platform must be orchestrated by MSO in order to execute requests +via APPC which then invoke VNF level playbooks. Playbooks that impact +more than a single VNF are not the current focus of these guidelines. + +Since last release of these guidelines, based on recent learnings, +moving VNF Type global variables under inventory/group_vars files, this +way variables and respective values are available to all playbooks without +being explicitly referenced though an include statement. Also creating +templates that are VNF Type specific, but moving away from static files +that are VNF instance specific, working to obtain VNF instance specific +from other sources, inventory database, etc. + +And here the scrubbed default arguments for this VNF instance(originated +from previously re-factored playbooks now being phased out): + +.. code-block:: none + + vnf_instance=vfdb9904v + + $ more ../vars/vfdb9904v/default_args.yml + vm_config_oam_vnfc_name: vfdb9904vm001oam001 + vm_config_oam_hostname: vfdb9904vm001 + vm_config_oam_provider_ip_address: 1xx.2yy.zzz.109 + … + +IMPORTANT: The APPC and default file attribute name for +vm\_config\_oam\_vnfc\_name, as an example, is derived from vm\_config +array structure (list) in the CSAR package ENV file, with dots replaced +by underscore: + +.. code-block:: none + + vm_config: + + oam: {vnfc_name: {{ vm_config_oam_vnfc_name }}, hostname: {{ + vm_config_oam_hostname }}, provider_ip_address: {{ + vm_config_oam_provider_ip_address } + }, + … + +Parameters like VNF names, VNFC names, OA&M IP addresses, after +February, 2018 ONAP release, will be extracted from A&AI by APPC and +then passed down to Ansible Server, as part of APPC request through REST +API. In the meantime, VNF instance specific required values, will +be stored on VNF instance directory, default arguments file and will be +used as defaults.

Moving to extract these values from +inventory databases and provide them to Ansible Server as part of the APPC +request, but may be used in a transition from having everything stored in the +Ansible Server to APPC extracting and providing VNF instance specific +attribute-value pairs to the Ansible Server as part of the request. + +Files containing attribute name value pairs (variable name and default +values), referenced/included by playbooks – created dynamically by +playbooks: + +To avoid +overwrites or collisions of multiple concurrently running VNF instance +requests, files created dynamically by playbooks, based on VNF generic +templates, combined with default values and arguments passed down by +APPC (as part of the request), shall be stored under a directory with +VNF instance name on the path. + +Example: + +tmp/<VNF\_instance\_name>/all.yml + +Files containing site specific (Openstack location non-instance +specific) attribute name value pairs, like NTP server and DNS server’s +IP addresses and other parameters, referenced/included by playbooks, not +VNF specific – Could/should be stored under inventory/group_vars directory, +in a subdirectory named after the string used to identify the site (nyc1, +lax2,…). + +Examples: + +ansible/inventory/group_vars/<Site> + +ansible/inventory/group_vars/nyc1 + +ansible/inventory/group_vars/lax2 + + +\ **Ansible Server Design - Directory Structure** + +To help understanding the contents of this section, here are few basic +definitions: + +**VNF type a.k.a VNF Function Code** - Based on current Services +Platform naming convention, each Virtual Network Function is assigned a +4 character string (example vfdb), these are 4 characters in +the VNF instance name, followed by (4) numbers, ending in a "v", but the +naming convention is evolving. VNF instance name in +some cases corresponds to the stack name for the VNF when VNF instance +is built based on a single module, single stack. Example of VNF instance +name: vfdb9904v. All VNF performing this function, running the same +software, coming from the same VNF provider will have the same 4 +characters in the VNF instance name, in this example, vfdb. + +NOTE: New naming convention includes a prefix indicating geographical +location where VNF is instantiated. + +VNF type, determined through these 4 characters, is also known as VNF +Function Code and is assigned by inventory team. All Services Platform +VNF Function Codes can be found in inventory database and/or A&AI as +well as Services Platform Network Design Documents. + +Version – As in VNF software version is the release of the software +running on the VNF for which the playbooks were developed. VNF +configuration steps may change from release to release and this +<Version> in the path will allow the Ansible Server to host playbooks +associated with each software release. And run the playbooks that match +the software release running on each VNF instance. APPC initially will +not support playbook versioning only latest playbook is supported or a hard +coded version that later should become a variable to allow multiple +actively in use playbook versions according to VNF release. + +Playbook Function - Is a name associated with a life cycle management +task(s) performed by the playbook(s) stored in this directory. It should +clearly identify the type of action(s) performed by the main playbook +and possibly other playbooks stored in this same directory. Ideally, +playbook function would match APPC corresponding command or function that +is performed by the main playbook in this directory. Following Ansible naming +standards main playbook is usually named site.yml. There can be other +playbooks on the same directory that use a subset of the roles used by the +main playbook site.yml. Examples of Playbook Function directory names: + +- configure – Contains post-instantiation (bulk) configuration + playbooks, roles,… + +- healthcheck – Contains VNF health check playbook(s), roles,… + +- stop – Contains VNF application stop (stopApplication) playbook(s), + roles,… + +- start – Contains VNF application start (startApplication) playbook(s), + roles,… + +Directory structure to allow hosting multiple version sets of playbooks, +for the same VNF type, to be hosted in the runtime environment on the +Ansible Servers. Generic directory structure: + +Ansible Playbooks – Function directory and main playbook: + +.. code-block:: none + + <VNF type>/<Version>/ansible/<Playbook Function>/site.yml + +Example – Post-instantiation (bulk) configuration –APPC Function - +Configure: + +.. code-block:: none + + <VNF type>/<Version>/ansible/configure/site.yml + +Example – Post-instantiation (bulk) configuration –APPC Function +– Configure – VNF software version 16.1: + +.. code-block:: none + + vfdb/V16.1/ansible/configure/site.yml + +Example – Health-check –APPC Function - HealthCheck: + +.. code-block:: none + + <VNF type>/<Version>/ansible/healthcheck/site.yml + +OR (Function directory name does not need to match APPC function name) + +.. code-block:: none + + <VNF type>/<Version>/ansible/check/site.yml + +Ansible Directories for other artifacts – VNF inventory hosts file - +Required: + +.. code-block:: none + + <VNF type>/<Version>/ansible/inventory/<VNF instance name>hosts + +Ansible Directories for other artifacts – VNF instance specific default +arguments – Optional: + +.. code-block:: none + + <VNF type>/<Version>/ansible/group_vars/<VNF instance name> + +NOTE: This requirement is expected to be deprecated all or in part in the +future, for automated actions, once APPC can pass down all VNF specific +arguments for each action. Requirement remains while manual actions are +to be supported. Other automated inventory management mechanisms may be +considered in the future, Ansible supports many automated inventory +management mechanisms/tools/solutions. + +Ansible Directories for other artifacts – VNF (special) groups – +Optional: + +.. code-block:: none + + <VNF type>/<Version>/ansible/inventory/group_vars/<VNF instance name> + +NOTE: Default groups will be created based on VNFC type, 3 characters, +on VNFC name. Example: “oam”, “rdb”, “dbs”, “man”, “iox”, “app”,… + +Ansible Directories for other artifacts – VNF (special) other files – +Optional – Example – License file: + +.. code-block:: none + + <VNF type>/<Version>/ansible/<Other directory(s)> + +CAUTION: On referenced files used/required by playbooks. + +- To avoid missing files, during on-boarding or uploading of Ansible + Playbooks and related artifacts, all permanent files (not generated + by playbooks as part of execution), required to run any playbook, + shall reside under the ansible root directory or below on other + subdirectories. + +- Any references to files, on includes or other playbook entries, shall + use relative paths. + +- This is the ansible (root) directory referenced on this + note (Ansible Server mount point not included): + +.. code-block:: none + + <VNF type>/<Version>/ansible/ + +There will be a soft link to the latest set of Ansible Playbooks for +each VNF type. + +VNF type directories use A&AI inventory VNF function code. Ansible +Playbooks will be stored on a Cinder Volume mounted on the Ansible +Servers as /storage. Example: + +/storage/vfdb/latest/ansible – This soft link point to the latest set of +playbooks (or the only set) + +/storage/vfdb/V16.1/ansible – Root directory for database VNF Ansible +Playbooks for release 16.1 + +CAUTION: To support this directory structure as the repository to store +Ansible Playbooks run by APPC, APPC API in the Ansible Server side needs +to be configured to run playbooks from directory, not MySQL database. + +Ansible Server HTTP will be configured to support APPC REST API requests +to run playbooks as needed, against specific VNF instances, or specific +VM(s) as specified in the request. + +ONAP APPC REST API to Ansible Server is documented separately and can be +found under ONAP (onap.org). + +**Ansible Server – On-boarding Ansible Playbooks** + +Once playbooks are developed following the guidelines listed in prior +section(s), playbooks need to be on-boarded onto Ansible Server(s). In +the future, they’ll be on-boarded and distributed through ONAP, at least +that is the proposed plan, but for now they need to be uploaded +manually. There is work in progress to use a Git as the playbook +repository to store and track playbooks by version, version control. + +These are the basic steps to on-board playbooks manually onto the +Ansible Server. + +1. Upload CSAR, zip, or tar file containing VNF playbooks and related + artifacts. + +2. Create full directory (using –p option below) to store Ansible + Playbooks and other artifacts under /storage (or other configured) + file system. + + a. Includes VNF type using VNF function code 4 characters under + /storage. + + b. Includes VNF “Version” directory as part of the path to store + playbooks for this VNF version. + + c. Include generic ansible root directory. Creating full directory + path as an example: + +.. code-block:: none + + $ mkdir –p /storage/vfdb/V16.1/ansible**/** + +3. Make this directory (VNF ansible root directory) current directory + for next few steps: + +.. code-block:: none + + cd /storage/vfdb/V16.1/ansible/ + +4. Extract Ansible Playbooks and other Ansible artifacts associated with + the playbooks onto the ansible directory. Command depends on the type + of file uploaded, examples would be: + +.. code-block:: none + + tar xvf .. + unzip … + bunzip .. + +5. Create VNF inventory hosts file with all VMs and + OA&M IP addresses for all VNF instances with known OA&M IP addresses + for respective VMs, example: + +.. code-block:: none + + $ mkdir inventory + + $ touch inventory/vfdb9904vhosts + + $ cat inventory/vfdb9904vhosts + + [host] + localhost ansible\_connection=local + + [oam] + 1xx.2yy.zzz.109 + 1xx.2yy.zzz.110 + + [rdb] + 1xx.2yy.zzz.105 + 1xx.2yy.zzz.106 + +6. (Optional, being deprecated) Create directory to hold default +arguments for each VNF instance, +example: + +.. code-block:: none + + $ mkdir –p vars/vfdb9904v + $ touch vars/vfdb9904v/default\_args.yml + $ cat vars/vfdb9904v/default\_args.yml + vm\_config\_oam1\_vnfc\_name: vfdb9904vm001oam001 + vm\_config\_oam1\_hostname: vfdb9904vm001 + vm\_config\_oam1\_provider\_ip\_address: 1xx.2yy.zzz.109 + + vm\_config\_oam2\_vnfc\_name: vfdb9904vm002oam001 + vm\_config\_oam2\_hostname: vfdb9904vm002 + vm\_config\_oam2\_provider\_ip\_address: 1xx.2yy.zzz.110 + + vm\_config\_rdb1\_vnfc\_name: vfdb9904vm003rdb001 + vm\_config\_rdb1\_hostname: vfdb9904vm003 + vm\_config\_rdb1\_provider\_ip\_address: 1xx.2yy.zzz.105 + + vm\_config\_rdb2\_vnfc\_name: vfdb9904vm004rdb001 + vm\_config\_rdb2\_hostname: vfdb9904vm004 + vm\_config\_rdb2\_provider\_ip\_address: 1xx.2yy.zzz.106 + + vm\_config\_rdb3\_vnfc\_name: vfdb9904vm005rdb001 + vm\_config\_rdb3\_hostname: vfdb9904vm005 + vm\_config\_rdb3\_provider\_ip\_address: 1xx.2yy.zzz.xxx + + vm\_config\_rdb4\_vnfc\_name: vfdb9904vm006rdb001 + vm\_config\_rdb4\_hostname: vfdb9904vm006 + vm\_config\_rdb4\_provider\_ip\_address: 1xx.2yy.zzz.yyy + +NOTE: Please note names in this file shall use underscore “\_” not dots +“.” or dashes “-“. + +7. Perform some basic playbook validation running with “--check” option, + running dummy playbooks or other. + +NOTE: Each Ansible Server or cluster of Ansible Server will have its own +credentials to authenticate to VNF VMs. Ansible Server SSH public key(s) +have to be loaded onto VNF VMs during instantiation or other way before +Ansible Server can access VNF VMs and run playbooks. HOT templates used +by heat to instantiate VNFs to be configured by these Ansible Servers running +playbooks shall include the same SSH public key and load them onto VNF VM(s) +as part of instantiation. + +Other non-vendor specific playbook tasks need to be incorporated in overall +post-instantiation configuration playbook.
