Verify dashboard configuration

 Note also that nonrtric/dashboard/webapp-backend/src/main/resources/application.properties default property value policycontroller.url.prefix = http://policy-agent-container:8081 assumes that policy agent is started with name policy-agent-container and exposes port 8081 (as is done below)! 

Build the code and create docker images

To build all non RT-RIC components.docker images of sdnc-a1-controller, policy-agent, near-rt-ric-simulator and nonrtric-dashboard:

cd nonrtric
mvn clean install -Dmaven.test.skip=true

Run A1 Controller Docker Container

...

• Run docker container using this command: 

  docker run -p 8081:8081 --network=nonrtric-docker-net --name=policy-agent-container o-ran-sc/nonrtric-policy-agent:1.0.0-SNAPSHOT
  

Automatic A1 Client selection

After starting Once policy-agent is up and running, it establishes connections to all configured NearRT-RICs. Policy-agent It has multiple A1 clients to select from and selection is done dynamically based on connectivity. Selection of A1 client is not clearly visible for user and poli, but policy-agent logs can be grepped to see which client was selected.

E.g. here's 2 example grepping where either SDNC The two grepping examples below show how either SDNC_OSC A1 client or STD A1 client was selected i.e. option - these translate into options A and B described on the Testing End to End call in release A page.
