In the current implementation, detaching from a container started with `nerdctl run --rm ...` unexpectedly removes it. The behaviour before this modification is as follows. ``` > nerdctl run --rm -it --detach-keys=ctrl-a,ctrl-b --name test alpine / # INFO[0002] read detach keys > nerdctl ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ``` When the same operaton is performed in the Docker CLI, the container will not be deleted. This issue is reported in the following: - containerd#3568 Therefore, this commit resolves this behaviour of a container not being deleted on detachment. Note that the behaviour after this modification is as follows. ``` > nerdctl run --rm -it --detach-keys=ctrl-a,ctrl-b --name test alpine / # INFO[0010] read detach keys > nerdctl ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 46f4c829e5cc docker.io/library/alpine:latest "/bin/sh" 15 seconds ago Up test ``` Signed-off-by: Hayato Kiwata <[email protected]>

The detailed behaviour is as follows. ``` > nerdctl attach test / # exit > nerdctl ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ``` Signed-off-by: Hayato Kiwata <[email protected]>
