What does the exclamation point in a triangle mean?

[vincenzon]

I've started seeing two containers (consistently the same two) in a docker compose group of 12 containers get this exclamation point in a triangle icon next to them in the left side panel. I don't see any errors on hover, and just using the docker command line I can't discover what the extension is alarming on. What I do know is that the containers are indeed in some way broken because if I try to stop them docker hangs. I actually have to restart the docker daemon to recover. I am hoping that if I knew what the extension seems to know, I can debug this further.

Is there some log line discoverable somewhere that will show why the extension is showing a exclamation point in a triangle?

Thank you for any help,

Matt

Oh, I see, it reflects the unhealthy status of the container.
