This page describes how to get the Istanbul release version of A1-Policy functions up and running using Docker.
The A1 Policy Management Service and the (optional) A1-enabled Controller (SDNC with A1-Adapter) will run in a local demonstrative deployment with four near-RT-RIC A1 simulator instances (docker containers). These simulators will be configured to emulate devices implementing either the "OSC_2.1.0" version or "STD_2.0.0" version of the O-RAN A1 interface. (For more information on the OSC A1 Simulator functions see OSC NONRTRIC Wiki page (Release H))
All components run as docker containers and communicate via a private docker network. Details of the architecture can be found from London 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)
To support local test with four separate near-RT-RIC simulator instances:
Copy the default configuration file oran/a1-policy-management/config/application_configuration.json (london) 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.
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:

For more information on configuring the A1-Policy Management Service please see London - Component configuration
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), and check the version number in appropriate POM files if building manually.
| Component | Release image and version tag | Staging images and version tag | Manual snapshot (only available if manually built) and version tag |
|---|---|---|---|
| A1 Policy Management Service | nexus3.onap.org:10002/onap/ccsdk-oran-a1policymanagementservice:1.5.0 | nexus3.onap.org:10004/onap/ccsdk-oran-a1policymanagementservice:1.5.1-STAGING-latest | onap/ccsdk-oran-a1policymanagementservice:1.5.1-SNAPSHOT |
| SDNC image | nexus3.onap.org:10002/onap/sdnc-image:2.5.5 | nexus3.onap.org:10004/onap/sdnc-image:2.5.5-STAGING-latest | onap/sdnc-image:2.5.5-SNAPSHOT |
| If you choose to bypass the A1-Controller (SDNC + A1-Adapter), there is no need to start it, so you can skip this step. |
To use the A1 Controller function (SDNC + A1-Adapter) you need to run the SDNC docker image. This image has few other docker image dependencies but not all are important for A1 Policy functions. To run a cut-down SDNC container for A1 Policy testing a number of the unneeded services can be removed from the docker compose file. (It is often difficult to get a full SDNC deployment up & running; removing unneeded components makes this easier)
Download and edit the docker compose file, oam/installation/src/main/yaml/docker-compose.yaml (london) and keep only sdnc and maria db images. The rest of the images are not needed 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.)
Download the sdnc-basic.yml (Gerrit - london) (or) sdnc-basic.yaml (wiki)
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:2.5.5
Locally built | Release image from nexus |
|---|---|
sdnc: | sdnc: |
(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:2.5.5. 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 docker-compose files above requires several environment variables to be set according to your environment.
Sample settings for these environment variables can be found here (london), but first check if these values are suitable for your environment.
export MTU=1500 docker network create nonrtric-docker-net docker-compose up (In a new shell) docker network connect nonrtric-docker-net sdnc_controller |
The SDNC image will take quite a while to install all features into the Karaf Server. You can check the logs of the server at /opt/opendaylight/data/log/karaf.log
Another useful log to check is /opt/opendaylight/data/log/A1-Adapter.log to see log entries related to the SLI DG operation inside the A1-Adapter.
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)
http://localhost:8282/apidoc/explorer/index.html (or) http://<yourclusterloginip>/apidoc/explorer/index.html |
(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
Start docker containers for each near-RT-RIC defined in oran/a1-policy-management/config/application_configuration.json in the step "Configure the A1 Policy Management Service" above.
Different Simulators can use different A1-Interface profiles, for example OSC_2.1.0 and STD_2.0.0 below. Start each simulator instance with the following commands (use separate shells):
(Each in a new shell) docker run -p 8085:8085 -p 8185:8185 -e A1_VERSION=OSC_2.1.0 -e ALLOW_HTTP=true --network=nonrtric-docker-net --name=ric1 nexus3.o-ran-sc.org:10002/o-ran-sc/a1-simulator:2.5.0 docker run -p 8086:8085 -p 8186:8185 -e A1_VERSION=OSC_2.1.0 -e ALLOW_HTTP=true --network=nonrtric-docker-net --name=ric2 nexus3.o-ran-sc.org:10002/o-ran-sc/a1-simulator:2.5.0 docker run -p 8087:8085 -p 8187:8185 -e A1_VERSION=STD_2.0.0 -e ALLOW_HTTP=true --network=nonrtric-docker-net --name=ric3 nexus3.o-ran-sc.org:10002/o-ran-sc/a1-simulator:2.5.0 docker run -p 8088:8085 -p 8188:8185 -e A1_VERSION=STD_2.0.0 -e ALLOW_HTTP=true --network=nonrtric-docker-net --name=ric4 nexus3.o-ran-sc.org:10002/o-ran-sc/a1-simulator:2.5.0 |
(Note these commands create a deployment scenario aligned towards the sample A1 Policy configuration given above)
(Note these commands can be run in the background - all in one shell - by using docker run -d -p ..... )
For the OSC.2.1.0 simulators create a new A1 Policy Type policy type definition (JSON), and load it into each of the OSC.2.1.0 A1 Simulators instances.
(Note the format for A1 Policy Type Definitions (JSON) differs for different A1-Interface profiles)

Insert the example policy type into the started OSC_2.1.0 A1 Simulator instances by running these curl commands (in this example to ric1 exposed to port 8085 and ric2 exposed to port 8086):
curl -X PUT -v "http://localhost:8085/a1-p/policytypes/1" -H "accept: application/json" \ -H "Content-Type: application/json" --data-binary @pt1.json curl -X PUT -v "http://localhost:8086/a1-p/policytypes/1" -H "accept: application/json" \ -H "Content-Type: application/json" --data-binary @pt1.json |
For the STD_2.0.0 simulators create a new A1 Policy Type policy type definition (JSON), and load it into each of the STD_2.0.0 A1 Simulators instances.
(Note the format for A1 Policy Type Definitions (JSON) differs for different A1-Interface profiles)

For more details about running the OSC A1 Simulator see the related OSC NONRTRIC Wiki page (Release H) and OSC A1 Simulator Documentation (H Release)
Run A1 Policy Management Service docker container using the command below, after the A1-Controller and simulators have been fully started.
It may be useful to set the logging level to TRACE level, where you can verify the A1-Controller, A1-Simualtors and A1 Policy Management Service is fully up and running.
The configuration file (application_configuration.json described above) must be mounted as a volume into the container, so absolute path and name of the file must be substituted in the following command:
docker run -p 8081:8081 --network=nonrtric-docker-net --name=a1policymanagmentservice --volume **<Absolute path to application_configuration.json created above>**:/opt/app/policy-agent/data/application_configuration.json nexus3.onap.org:10002/onap/ccsdk-oran-a1policymanagementservice:1.5.0 |
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)
curl -X POST http://localhost:8081/actuator/loggers/org.onap.ccsdk.oran.a1policymanagementservice -H "Content-Type:application/json" -d {\"configuredLevel\":\"trace\"} |
Once the Policy Management Service is up and running, it establishes connections to all configured near-RT-RICs (ric1, ric2, ric3, ric4) via the A1 Controller.
If the a1policymanagmentservice container is configured to log at TRACE level, the following logs entries should appear indicating that connection to the configured RICs has been established successfully via A1 Controller.
docker logs a1policymanagmentservice | grep "checked" 2022-03-16 14:15:03.805 DEBUG 1 --- [or-http-epoll-5] o.o.c.o.a.tasks.RicSupervision : Ric: ric1 checked OK 2022-03-16 14:15:03.816 DEBUG 1 --- [or-http-epoll-6] o.o.c.o.a.tasks.RicSupervision : Ric: ric3 checked OK 2022-03-16 14:15:03.835 DEBUG 1 --- [or-http-epoll-1] o.o.c.o.a.tasks.RicSupervision : Ric: ric2 checked OK 2022-03-16 14:15:03.851 DEBUG 1 --- [or-http-epoll-2] o.o.c.o.a.tasks.RicSupervision : Ric: ric4 checked OK |
For troubleshooting/verification purposes you can view/access the A1 Policy Management Service swagger API from url: http://localhost:8081/swagger-ui.html
Note: the hostname may be different depending on your environment, port 8081 is configured in the docker command above
The OSC Non-RT RIC Control Panel uses two docker images, one is the Control Panel API Gateway (backend) and the Non-RT RIC Control Panel (frontend).
In order to start the Control Panel API gateway, an configuration file is needed to specify the routes and paths accepted by the gateway and where those requests will be redirect to, so the following example can be used:
server:
port: 9090
spring:
cloud:
gateway:
httpclient:
ssl:
useInsecureTrustManager: true
wiretap: true
httpserver:
wiretap: true
routes:
- id: A1-Policy
uri: http://a1policymanagmentservice:8081
predicates:
- Path=/a1-policy/**
management:
endpoint:
gateway:
enabled: true
endpoints:
web:
exposure:
include: "gateway,loggers,logfile,health,info,metrics,threaddump,heapdump"
logging:
level:
ROOT: ERROR
org.springframework: ERROR
org.springframework.cloud.gateway: INFO
reactor.netty: INFO
file:
name: /var/log/nonrtric-gateway/application.log
|
The configuration, application_nonrtricgateway.yaml must be mounted as a volume to the container.
Run docker container using this command:
It is important to provide absolute path of the application_nonrtricgateway.yaml file!
docker run -p 9090:9090 --network=nonrtric-docker-net --name=nonrtric-gateway --volume <Absolute path to application_nonrtricgateway.yaml created above>:/opt/app/nonrtric-gateway/config/application.yaml:ro nexus3.o-ran-sc.org:10002/o-ran-sc/nonrtric-gateway:1.2.0 |
Example:
docker run -p 9090:9090 --network=nonrtric-docker-net --name=nonrtric-gateway --volume /home/infra/workspace/application-nonrtricgateway.yaml:/opt/app/nonrtric-gateway/config/application.yaml:ro nexus3.o-ran-sc.org:10002/o-ran-sc/nonrtric-gateway:1.2.0
In order to run docker container for control panel use the following command:
docker run -p 8080:8080 --network=nonrtric-docker-net --name=nonrtric-control-panel nexus3.o-ran-sc.org:10002/o-ran-sc/nonrtric-controlpanel:2.5.0 |
The Control Panel UI can be accessed by pointing the web-browser to this URL: http://localhost:8080/ (or) http://<yourclusterloginip>:8080/
Note: the hostname may be different depending on your environment. The port number is defined using the docker command above.
Example:
For each managed "RIC" (A1-Simulator) should be visible in the Control Panel display, with each of the A1 Policy Types defined & loaded above.
(Note: A1 Policy Types can only be created or deleted directly in the near-RT-RIC (or simulators), which will then be synchronized in the A1 Policy Management Service, and can seen in the Control Panel display when refreshed.)
A1 Policy instances for those A1 Policy Types can now be created, updated and deleted in the managed "RIC".
