This sounds terrifying to implement. I can't fathom how, if implemented, we would attempt to test such a thing. The burden of support and maintenance would be tremendous. Most of the "infrastructure playbooks" are a source of concern, and adding something like what is being proposed here would not improve that situation. This sounds more like an administrator task rather than a ceph-ansible responsibility (In reply to Alfredo Deza from comment #4) > This sounds terrifying to implement.

Note that in OSP we consume already two infrastructure playbooks: switch-from-non-containerized and rolling_update. We could just run the two, sequentially, to get cluster into the wanted state but that implies downloading a 2.x container image to do the initial migration to containers and then a 3.x container image to do the upgrade. Do you think that'd still be a better (safer maybe?) approach? I cant' tell how will that play out in a production environment. I'm still concerned on the wild permutations of environments and attempting to mangle them all with a single playbook. In short: I don't know how safe (if at all) is that approach. For now, this is pretty well handled by switch-from-non-containerized, we also have CI coverage for this. The mix of switch-from-non-containerized and rolling_update will be required. *** This bug has been marked as a duplicate of bug 1488566 *** |
