Please follow the editor's train of thought to study and learn "how to solve the problem that container service cannot be stopped or deleted in Docker".

Operation steps

(1) the directory of docker cannot be deleted by executing the delete command:

# ll / var/lib/docker/containers | grep caf8ef20f3c1# cd / var/lib/docker/containers # rm-rf caf8ef20f3c1c78f03a5844ee23abc1d7e44246f242292040f1ef288899d0cb8

At this time, we will receive an error like this:

Rm: cannot delete "/ var/lib/docker/containers/caf8ef20f3c1c78f03a5844ee23abc1d7e44246f242292040f1ef288899d0cb8/secrets": device or resource busy cannot delete "/ var/lib/docker/containers/caf8ef20f3c1c78f03a5844ee23abc1d7e44246f242292040f1ef288899d0cb8/shm": device or resource is busy

(2) from the error reported above, we can see that the shared mount of "secrets" and "shm" cannot be deleted. First, find the location of the mount, then cancel the mount, and then delete:

# cat / proc/mounts | grep "docker" | grep "caf8ef20f3c1"

(3) unmount:

# umount / data/sys/var/docker/containers/caf8ef20f3c1c78f03a5844ee23abc1d7e44246f242292040f1ef288899d0cb8/secrets# umount / data/sys/var/docker/containers/caf8ef20f3c1c78f03a5844ee23abc1d7e44246f242292040f1ef288899d0cb8/shm

(4) check again:

# cat / proc/mounts | grep "docker" | grep "caf8ef20f3c1" / / is no longer available

(5) now delete the directory of docker:

# cd / var/lib/docker/containers # rm-rf caf8ef20f3c1c78f03a5844ee23abc1d7e44246f242292040f1ef288899d0cb8

(6) Delete CCS

Now let's use rm or kill to delete the container service:

# docker rm-f caf8ef20f3c1c or # docker kill-- signal=SIGINT caf8ef20f3c1

If hang is stuck (stuck) after the above command is run, restart the docker service:
