Description David Vossel 2014-08-28 16:59:41 UTC

Description of problem:

We need to support managing docker containers in an HA environment in the same way virtual machines are already supported with the VirtualDomain resource-agent.

Additional info:

There is already an upstream resource-agent started that supports docker management. It can be found here. https://github.com/ClusterLabs/resource-agents/pull/370

Comment 6 michal novacek 2014-12-11 11:28:13 UTC

I have verified that the docker resource agent functionality seems correctr
with resource-agents-3.9.5-38.el7.x86_64
