What kind of container?</pre>

Well I would hope the solution is generic enough to work with any
container. But in my specific case, EC2 instances. Plus maybe docker
for development work.<br>

Most development was done with VirtualMachine which needs a unique name anyway (ie. cant be cloned).</pre>

With EC2 (and docker), you create an instance/container and the name
& address is returned after creation.<br>

Interesting concept though, I'm sure we can figure out some way to get it done.

<pre wrap="">The problem is that the `remote-node` meta parameter is set on the clone resource, and not the children. So I can't see a way to tell pacemaker the address of all the clone children containers that get created.
The only way I can see something like this being possible is if the resource agent set an attribute on the clone child when the child was started.
Is there any way to accomplish this? Or will I have to create separate resources for every single container? If this isn't possible, would this be considered as a future feature?
Thanks
