Return zero exit-code when force-removing non-existing containers When using `docker rm` / `docker container rm` with the `-f` / `--force` option, attempts to remove non-existing containers should print a warning, but should return a zero exit code ("successful"). Currently, a non-zero exit code is returned, marking the removal as "failed"; $ docker rm -fv 798c9471b695 Error: No such container: 798c9471b695 $ echo $? 1 The command should match the behavior of `rm` / `rm -f`, with the exception that a warning is printed (instead of silently ignored): Running `rm` with `-f` silences output and returns a zero exit code: touch some-file && rm -f no-such-file some-file; echo exit code: $?; ls -la # exit code: 0 # total 0 # drwxr-xr-x 2 sebastiaan staff 64 Aug 14 12:17 . # drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 .. mkdir some-directory && rm -rf no-such-directory some-directory; echo exit code: $?; ls -la # exit code: 0 # total 0 # drwxr-xr-x 2 sebastiaan staff 64 Aug 14 12:17 . # drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 .. Note that other reasons for a delete to fail should still result in a non-zero exit code, matching the behavior of `rm`. For instance, in the example below, the `rm` failed because directories can only be removed if the `-r` option is used; touch some-file && mkdir some-directory && rm -f some-directory no-such-file some-file; echo exit code: $?; ls -la # rm: some-directory: is a directory # exit code: 1 # total 0 # drwxr-xr-x 3 sebastiaan staff 96 Aug 14 14:15 . # drwxr-xr-x 199 sebastiaan staff 6368 Aug 14 12:13 .. # drwxr-xr-x 2 sebastiaan staff 64 Aug 14 14:15 some-directory This patch updates the `docker rm` / `docker container rm` command to not produce an error when attempting to remove a missing containers, and instead only print the error, but return a zero (0) exit code.
