@autonomic this is great, something i've been dreaming about :) unfortunately, in-dream-version was #ansible with debops.org (which would help with publishing and sharing roles, one of the cons for ansible you point out). that would also keep the #debian package as the packaging unit instead of docker images. this would be a simpler architecture. would require the implementation of the cluster/ha logic in ansible, but it'd be leaner and more modular and reusable, i think.
