Testing using xapp-onboarder CLI tools

1. Find out the ingress IP for your RIC instance. If you deploy RIC using it/dep deployment script, it should be your host(VM)'s IP.

2. Install xapp-onboarder CLI

   Code Block
   git clone "https://gerrit.o-ran-sc.org/r/it/dev" cd dev/xapp_onboarder pip3 install ./

   
   

3. Set up the environment variables for CLI connection

   Code Block
   export CHART_REPO_URL="http://<INGRESS_IP>:32080/helmrepo" # It should return True if your CLI tool is properly connected to the RIC instance cli health

    Make sure you can access the helm repo in your RIC instance.
