> Well, I had the advantage in that I already knew I wasn't touching it on Docker with a ten foot pole, and we use Ansible, so that made my google search pretty obvious.

But the thing is, docker shouldn't actually make things that much harder -- it's just the same old process + namespaces + cgroups. In theory not that much is different, I'm not sure why reality so often doesn't match up.

Yeah I got mega trapped. At one point I started walking back versions, trying them in lockstep (to get away from the maxConcurrentShardRequests and the NoShardAvailableActionException issue, before I realized that the latter issue was due to stale data on disk). I started bouncing between docker repos for this stuff -- elastic stopped publishing to dockerhub, but there's images like blacktop/kibana and bitnami/kibana who that still exist. Once I try again with a clear head I'm sure it will be easier.

Yeah I actually filed a ticket on the maxConcurrentShardRequests thing -- it seems like a real bug and it's waiting for triage.
