Page Comparison

This page describes how to get the Istanbul release version of A1-Policy functions up and running using Docker.

...

All components run as docker containers and communicate via a private docker network. Details of the architecture can be found from Kohn Release page.

Note: Version numbers used in this page may not be the most recent ... you should verify the latest version numbers for released pre-built components in the docker image repository (https://nexus3.onap.org)

...

• Java 11 (make sure that JAVA_HOME environment variable points to correct Java version)

• Maven 3.6 (make sure you have configured maven to access the ONAP maven repositories)
  

• Docker and docker-compose (latest)

...

• Copy the default configuration file oran/a1-policy-management/config/application_configuration.json (Kohn) to the current directory, then replace/amend the configuration with the sample demo configuration below.
  (Note the configuration below is just a sample, and should be updated to match particular deployments.  The deployment below assumes 4 near-RT-RICs exist - addressable at the URLs given. See the step "Run OSC Near-RT-RIC/A1 Simulator Docker Containers" below)

• The controller URL (hostname, port), username and password values to access the A1 Controller (SDNC + A1 Adapter) must match the values configured for the SDNC-A1-Controller. (See the step "Run A1 Controller" further below). The port number for http is 8181.
  (Note the configuration below is just a sample, and should be updated to match particular deployments.  The deployment below assumes an A1 Controller function (SDNC) exists - addressable at the url given, using the authentication credentials given.)

• Any defined ric host names (in the name and baseUrl for each ric entry) must match the given docker container names in near-RT-RIC simulator startup - port is always the simulator's internal port 8085 for http or 8185 for https.

• The A1 Policy Management service can entirely by-pass the A1-Controller (SDNC + A1 Adapter) if desired - it is optional to access the near-RT-RIC through an A1-Controller.
  

  Info
  title Alternative: Bypass the A1-Controller - connect direct from A1-Policy Management Service
  There is no functional gain in accessing the near-RT-RIC through an A1-Controller. To bypass the  A1-Controller (SDNC + A1 Adapter), where the A1-Policy Management Service connects directly to the A1 Interface: In the configuration the "controller" property is optional in the "ric" objects If all configured rics bypass the A1-Controller (do not have "controller" values) then the "controller" object at the top of the configuration can be omitted. If all configured rics bypass the A1-Controller there is no need to start an A1-Controller.

Run A1-enabled Controller

...

Download and edit the docker compose file, oam/installation/src/main/yaml/docker-compose.yaml (Kohn) and keep only sdnc and maria db images. The rest of the images are not need for A1 Policy testing.
In addition, remove or comment out the following two entries for sdnc in the docker-compose file: '- ansible' and  '- ansible:ansiblehost'. 
(However if you want to change the SLI DG graphs or run your own SLI DG graphs, then keep the dgbuilder image. If you wish to use the DMaaP interface then keep & configure the dmaaplistener image.)

Download the sdnc-basic.yaml yml file → https://gerrit.nordix.org/plugins/gitiles/onap/sdnc/oam/+/refs/heads/master/installation/src/main/yaml/sdnc-basic.yml (or) sdnc-basic.yaml

If you have built the images locally you don't need any other change, however if the images have not been built locally, versions should be modified, from latest to the version that you would like to use, for example: nexus3.onap.org:10002/onap/sdnc-image:2.45.05

 Locally built

Release image from nexus

sdnc:    
  image: onap/sdnc-image:latest

sdnc:
   image: nexus3.onap.org:10002/onap/sdnc-image:2.45.05

(There is also a file named sdnc_basic.yaml that can be used instead, it only includes maria db and sdnc so it only needs to be modified when images have not been built locally so versions need to be updated from latest to a specific version, for example nexus3.onap.org:10002/onap/sdnc-image:2.45.05. In this case when using a different docker compose file you will use docker-compose -f sdnc-basic.yml up instead of the normal docker-compose up command in the code block below)

...

The SDNC/ODL API GUI is also handy, where the internal A1-Policy APIs can be seen/tested. (It may take several minutes before the URLs work as expected as the SDNC/ODL component loads)

(Note these instructions create an A1 Controller deployment scenario aligned towards the sample A1 Policy configuration given above)

If the steps above are unsuccessful more help can be found from the CCSDK/SDNC Developer teams: CCSDK Project & SDNC Project
