Docker: a container's stats, health, events, shell and limits

Browse Source 
Five things the tab could not do, all on the container detail.

Stats draws CPU and memory over time from the container sensors the sampler already keeps,
so there is nothing new to collect.

Health shows the check's verdict, the failing streak and what the last five probes actually
printed, and says plainly when an image defines no health check at all rather than leaving
a blank panel.

Events asks Docker what has happened to the container over the last day, week or month —
started, died, killed, health going bad, with exit codes — rather than keeping a copy that
would only go stale.

Shell opens a session inside the container as an ordinary terminal, so it reattaches,
resizes and scrolls back like the rest and works on a managed machine through the same
proxy. The terminal manager grew a CreateCmd for it; every session is the same thing
afterwards.

Limits changes memory, CPUs and restart policy on the running container with docker update,
live and without recreating it. That is also the catch, and the dialog says so: it does not
edit the compose file, so a deploy puts back whatever the file says.
