Show c/storage (Buildah/CRI-O) containers in ps
The `podman ps --all` command will now show containers that are under the control of other c/storage container systems and the new `ps --storage` option will show only containers that are in c/storage but are not controlled by libpod. In the below examples, the '*working-container' entries were created by Buildah. ``` podman ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 9257ef8c786c docker.io/library/busybox:latest ls /etc 8 hours ago Exited (0) 8 hours ago gifted_jang d302c81856da docker.io/library/busybox:latest buildah 30 hours ago storage busybox-working-container 7a5a7b099d33 localhost/tom:latest ls -alF 30 hours ago Exited (0) 30 hours ago hopeful_hellman 01d601fca090 localhost/tom:latest ls -alf 30 hours ago Exited (1) 30 hours ago determined_panini ee58f429ff26 localhost/tom:latest buildah 33 hours ago storage alpine-working-container podman ps --external CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES d302c81856da docker.io/library/busybox:latest buildah 30 hours ago external busybox-working-container ee58f429ff26 localhost/tom:latest buildah 33 hours ago external alpine-working-container ``` Signed-off-by: TomSweeneyRedHat <tsweeney@redhat.com> Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
