What are the steps to create active/passive containers in Fuse ?

Issue

• I am trying to set up a active passive Fuse /karaf containers for the client in production , can you please provide me a link to the documentation. This is not for AMQ containers but for regular Karaf Containers.
• User has to setup the servers inorder to move to production and i am on field. They do not want the ensemble cluster but a specific active/passive setup for container where only one node is active all the time.
