colima: v0.6.x: "API error (500): Could not kill running container" "container 8d67c83751e6 PID 19180 is zombie and can not be killed"

Description

With DDEV I’ve never seen this before in previous versions of Colima, but I’ve now seen it and it’s been reported by others. On ddev stop:

API error (500): Could not kill running container 8d67c83751e67ee98571cb7c2b64794c30419ef9c9496791d34876dbd040dda3, cannot remove - container 8d67c83751e6 PID 19180 is zombie and can not be killed. Use the --init option when creating containers to run an init inside the container that forwards signals and reaps processes

Version

Operating System

Output of `colima status`

INFO[0000] colima is running using QEMU INFO[0000] arch: aarch64 INFO[0000] runtime: docker INFO[0000] mountType: sshfs INFO[0000] socket: unix:///Users/rfay/.colima/default/docker.sock

Reproduction Steps

It doesn’t happen every time, but does happen periodically on ddev stop, which is mostly the equivalent of docker stop followed by docker rm

Expected behaviour

I didn’t see this ever before.

I ran colima HEAD through 110 iterations of the breakit.sh script without failure. It was a new colima profile, which makes the test perhaps a little questionable, but it sure looked good.

Running full DDEV test suite now in https://github.com/ddev/ddev/pull/5549, that wasn’t able to succeed in v0.6.*, so fingers crossed now!

also no freezing on my end. and yes the message got displayed. even though it was called a zombie it doesnt behaved like one (except the container would be still present invisible to docker ps -astill). but here is the terminal output from yesterday. first the last few lines of ddev stop

Use the --init option when creating containers to run an init inside the container that forwards signals and reaps processes

and after the error took place i tested:

$> docker ps -a

i then started the same project again. and after the successful start i did another:

$> docker ps -a

the exited container was removed and there was a new ddev-traefik-router container running instead.

Thanks for reporting this.

Does it freeze or it only displays the message before stopping the container?
