Multi-tenancy needs authentication and authorization. Keycloack serves these two features.
In order to provide multi-tenancy of A&AI, A&AI can leverage Springboot security feature to interact with Keycloak. This document explains how to set up Keycloak and A&AI to provide essential authentication and authorization services for multi-tenancy

kubectl rollout restart deployments/dev-aai-resources -n onap

Test Multi-tenancy

Locally

In order to test multi-tenancy locally, you need to run aai-resource and aai-traversal as a single instance locallylocally, along with Keycloak and Cassandra, following steps below:

• Setup Keycloak and Cassandra by downloading a configuration zip file attached and run 

  Code Block
  docker-compose up

  
  

• Clone required repositories, aai-common, aai-resource and aai-traversal.

• Install aai-common with

  Code Block
  mvn clean install -DskipTests=true

  
  

• Modify application.properties file under aai- resources/aai-resources/src/main/resources directory. Change spring.profiles.active=production, one-way-ssl line to

  # Switch to keycloak
  spring.profiles.active=production, keycloak
  
  

• Modify application.properties file under aai-resources traversal/aai-traversal/src/main/resources directory. Change spring.profiles.active=production, one-way-ssl line to

  # Switch to keycloak
  spring.profiles.active=production, keycloak

• Run resources and traversal with the

  command

  commands below:  

  Code Block
  cd aai-resources mvn -N -P runAjsc -Dserver.local.startpath=src/main/resources/ cd aai-traversal mvn -N -P runAjsc -Dserver.local.startpath=src/main/resources/
