From 11e5c53d1191f7a324f212aa2ca2ec2aad1b4676 Mon Sep 17 00:00:00 2001 From: Boaz Shuster Date: Wed, 1 Jan 2020 09:53:25 +0200 Subject: Add the rmi flag to podman-run to delete container image The --rmi flag will delete the container image after its execution unless that image is already been used by another container(s). This is useful when one wants to execute a container once and remove any resources attached to it.
