Sometimes a container or a series of containers becomes unresponsive when Elastic server is not available so we can't: restart/stop/kill these containers. Docker logs command is not available for these containers. Docker stats is not available for all containers.
Last time we were able to reproduce the issue when there was no route no server via network while containers were running.
So here's an error message:
```auto
dockerd[64602]: time="2021-04-26T15:48:51+03:00" level=error msg="2021-04-26T12:48:51.645Z\tERROR\t[publisher_pipeline_output]\tpipeline/output.go:155\tFailed to connect to backoff(elasticsearch(http://...)): Get http://...: dial tcp ...: connect: no route to host
```
I can see that it tries to reconnect:
```auto
dockerd[64602]: time="2021-04-26T15:48:16+03:00" level=error msg="2021-04-26T12:48:16.915Z\tINFO\t[publisher_pipeline_output]\tpipeline/output.go:146\tAttempting to reconnect to backoff(elasticsearch

```
If i search logs for a container that's what i see:
```auto
Apr 26 15:02:20 ... dockerd[64602]: time="2021-04-26T15:02:20.808393367+03:00" level=info msg="Configured log driver does not support reads, enabling local file cache for container logs" container=095f572f6fd0233154210ba9f39b4073f44ab101431aa1fa22f711a981d242ef driver="elastic/elastic-logging-plugin:7.8.1"

```
When i tried to stop a container:
```auto

I suspect that this is an internal issue with docker that's a tad hard to fix: if we don't continuously read from the container's logging interface, stdio calls will eventually block. About how long is ES unavailable for?

Container gets stuck immediatly. If we get ES up it doesn't unstuck.
There was a bug in fluentd plugin ([Properly stop logger during (re)connect failure · akerouanton/fluent-logger-golang@8ae97ca · GitHub](https://github.com/akerouanton/fluent-logger-golang/commit/8ae97ca5c2f1a707583aefe710802fc76eef30aa)) that caused people exactly the same situation we have with Elastic logging plugin, maybe it has the same or similar issue?

I assume i can create a github ticket with this issue?
