How to force quit containers/system

[bishabosha]

My mac was on sleep overnight, now any command i try to shut down a particular container hangs (docker.io/library/ubuntu:25.04)

so container kill <id>, container system stop, container kill --all.

How do i do it for real, e.g. look for a service or particular process, if the CLI apparently doesnt have the power to quit, or maybe theres a deadlock bug.

I would hope i dont need to shut down the whole computer

Answering myself but containers are managed by launchd, so you can find your specific container with
launchctl list | grep container and probably see something like <pid> 0 com.apple.container.container-runtime-linux.<container ID>.

Then you can kill the process manually:

• e.g. launchctl kill 9 gui/<UID>/com.apple.container.container-runtime-linux.<container ID>
• get your UID (user ID) with id command

Killing the container manually seems to mess with container ls bookkeeping (as it still thinks its alive), but the container is definitely killed, and you can start it again as normal
