There's really two main options. You can either install the containers manually on each host and then use fabric:join to connect them to your existing fabric. Or, from your fabric you can use container-create-ssh to push installations to the remote nodes. Docs on container-create-ssh are here -> https://access.redhat.com/site/documentation/en-US/JBoss_Fuse/6.0/html/Console_Reference/files/ConsoleFabricContainerCreateSsh.html. Also note that the Management Console also provides a UI for creating containers via SSH as well.
Thank you for the reply. I understand each of the commands from the man pages, per se, and even the highly trivialized examples. But looking at these and understanding how a fabric is built and works in a non-trivial, deployed system is like trying to understand an impressionist painting by looking at individual brush strokes.
