From 0e36e65eaa1bab89b5d0a7a66253338e723429c5 Mon Sep 17 00:00:00 2001 From: Daniel J Walsh Date: Sun, 7 Mar 2021 06:11:54 -0500 Subject: Allow users to generate a kubernetes yaml off non running containers Currently if you attempt to create a kube.yaml file off of a non running container where the container runs as a specific User, the creation fails because the storage container is not mounted. Podman is supposed to read the /etc/passwd entry inside of the container but since the container is not mounted, the c.State.Mountpoint == "". Podman incorrectly attempts to read /etc/passwd on the host, and fails if the specified user is not in the hosts /etc/passwd. This PR mounts the storage container, if it was not mounted so the read succeeds.
