Manual Configuration:

This configuration is required to enable the ranSlice features in SDN-R.

SDNC:

•  Create the below environment variable in the helm chart at kubernetes/sdnc/templates/statefulset.yaml (for sdnc container). 

...

• Make the SDNC chart and then deploy.
• Execute the following command to log into the sdnc container 
  1. kubectl exec -it dev-sdnc-0 bash 
• Once in the docker container, edit the properties file  /opt/onap/ccsdk/data/properties/ran-slice-api-dg.properties
  •  update the following flag to true.
    1. ransim-mounted=true
    2. configdb-deployed=false  (set to true if configDB is used)
    3. cps-deployed=true   (set to true if cps is used)
  • Update IP address for ConfigDB:
    1. configdb.url=${CONFIG_DB_URL:-http://<IPAddress>:8086/api/sdnc-config-db/v4}
  • Update IP address for CPS-TBDMT:
    1. restapi.cps.anchors.endpoint=${CPS_URL:-http://<IPAddress>:8883}/cps/api/v1/dataspaces/E2EDemo/anchors

POLICY:

If old image is used:

...

• Login to the policy-drools-pdp

...

           command: ["sh","-c"]
           args: ["if [ -f {{ .Values.certInitializer.credsPath }}/.ci ]; then \
                   source {{ .Values.certInitializer.credsPath }}/.ci; fi;\
+                  echo 'actor.service.SO.operations.Modify\\ NSSI.path=3gppservices/v1/modify' >> /opt/app/policy/config/event-manager.properties; \
                   cp {{ .Values.certInitializer.credsPath }}/org.onap.policy.p12 ${POLICY_HOME}/etc/ssl/policy-keystore;\
                   /opt/app/policy/bin/pdpd-cl-entrypoint.sh boot"]

• Make the Policy chart and then deploy.

Deployment Prerequisite/dependencies

1. DMaaP, Policy, SO and SDNC pods should be up and running.

2. VES, PM mapper and DataFile Collector service should be running.
3. ConfigDB container should be running(if configDb is disabled in slice-analysis, CPS and CPS-TBDMT containers  should be running).

To run the Netconf Servers:

1. cd ran-sim/hcsim-content/gnbsim/honeycomb

...

         After execution of the above script, these servers will be mounted in SDNC(check ransim and SDNR logs if the mount request is successful for all the servers). 

         Access the restconf page to view the mounted servers: https://<WorkerVMIpAddress>:30267/apidoc/explorer/index.html

Setup SFPT:

1. Run the below docker command in the VM where you have setup the netconf servers:

           docker run -v /home/$USER/upload:/home/$USER/sftptest/upload -p 2222:22 -d atmoz/sftp $USER:pass:1001

      2. Give chmod 777 to upload folder which will be created automatically in the home dir.

        "vesEventListenerUrl": "https://<IPAddress>:30417/eventListener/v7"
      }
6. Update honeycomb  IP address at hc/docker-compose.yml file.
7. Step 2(Updating IP Address in config/gnbsim.json) and Step 3(Updating IP Address in docker-compose.yml file) is repeated for all folders (hc, hc-1, cucp1, cucp2, cuup1,cuup2, du1, du2, du3, du4, du5, du6)

      2. Run the up.sh script in ran-sim/hcsim-content/gnbsim/honeycomb. (wait for all the honeycomb servers to come up)

         After execution of the above script, these servers will be mounted in SDNC(check ransim and SDNR logs if the mount request is successful for all the servers). 

         Access the restconf page to view the mounted servers: https://<WorkerVMIpAddress>:30267/apidoc/explorer/index.html

Setup SFPT:

1. Run the below docker command in the VM where you have setup the netconf servers:

           docker run -v /home/$USER/upload:/home/$USER/sftptest/upload -p 2222:22 -d atmoz/sftp $USER:pass:1001
