Subject: [PATCH] podman: make sure to remove containers with lingering exec
|
|
|
83967c |
sessions
|
|
|
83967c |
|
|
|
83967c |
It may happen that some "podman exec" commands don't finish
|
|
|
83967c |
cleanly and leave lingering "Exec sessions" in the container's
|
|
|
83967c |
state. In that case, a "podman rm" command will always fail.
|
|
|
83967c |
|
|
|
83967c |
To overcome the podman bug, issue a "podman rm -f" command when
|
|
|
83967c |
we detect a container is stopped but still has some lingering
|
|
|
83967c |
"Exec sessions" associated with it.
