This setup is fine and should have no problem with future Pacemaker
versions, but FYI, since Pacemaker 1.1.17 there is a new feature called
"bundles" that simplifies running a Docker (or since 1.1.18, rkt)
container together with storage and IP addresses.

crm_attribute currently requires the libcrmcluster library, not
installed on remote nodes by default, to get the local node name if
none is specified. The only way around it currently is to install the
main pacemaker package on the remote nodes, even though you won't use
it (and obviously shouldn't enable it).

This is planned to be addressed later this year.
