docker rename not reflected in the UI

[rade]

1. launch scope
2. docker run --name=foo -dti ubuntu -> 'foo' shows up in scope
3. docker rename foo bar -> no change, even after waiting for a few minutes, clicking redraw, switching views etc

Note that the host details panel also shows the container as 'foo' instead of 'bar':

but it's definitely (now) called 'bar':

$ docker ps -a
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS               NAMES
8f1fc8133014        ubuntu                    "/bin/bash"              5 minutes ago       Up 5 minutes                            bar
d6ef255fe439        weaveworks/scope:latest   "/home/weave/entrypoi"   5 minutes ago       Up 5 minutes                            weavescope

Restarting scope didn't solve the problem either! However, reloading the page (or just clicking 'redraw') afterwards did.

Mmm, we are not propagating these changes into the canvas very well atm, we have a fix in the metrics-on-canvas stuff.

@tomwilkie was speculating that renames perhaps do not trigger docker events, and that docker events are the only thing that would currently prompt the probe to look at a container again.

[tomwilkie]

Yes this is a backend issue, although you're welcome to come play in goland @foot!

hahah cheers @tomwilkie I will take you up on that one day.

Give us a shout if it doesn't propagate all the way through the JS layer though (w/out reloading the page).

Am debating if we should also handle the oom event. There's no docker docs on when it is emitted, but I assume it is emitted when the container is oom-killed... Possibly it emits a destroy/die event also, though...
