restarting containers shown as 'running'

[rade]

running 0.12...

Notice how the state is shown as 'running', yet there is none of the information - metrics, applications, etc - I'd expect to see of a running container. And the reason is that the container isn't actually running. It was started with

$ docker run --restart=always -dti ubuntu sleep 0.2

and is currently restarting.

docker inspect shows

...
        "State": {
            "Status": "restarting",
            "Running": true,
            "Paused": false,
            "Restarting": true,
            "OOMKilled": false,
            "Dead": false,
            "Pid": 0,
            "ExitCode": 0,
            "Error": "",
            "StartedAt": "2016-02-17T14:01:45.304670287Z",
            "FinishedAt": "2016-02-17T14:01:45.521808095Z"
        },
...

NB: State.Status is a new(ish) field; older Dockers don't have it.

State.Status is also not present in the docker client library we're using, so probably want to update that.

Looks like it was added in docker 1.9

The alternative is to look at the combination of State.Running and State.Restarting, since that works across versions. That's what we are doing in Weave Net.

and State.OOMKilled, and State.Dead....

and State.OOMKilled, and State.Dead....

I am pretty sure State.Running=false for these.

[paulbellamy]

ah. Will check what docker does

Docker has a nice function for converting the container state into a human-readable string (used in docker ps). So we could show the state as: e.g. Restarting (0) 17 seconds ago, and Up 23 hours. Or we could show something like: running, paused, restarting, etc...
Either way we have to patch and update the go-dockerclient library. I quite prefer the more human-readable versions for display in the UI.
