Sometimes we have to check what's inside prepared docker image, but it might be hard debug it. Nothing far from that.Here is little solution. To explain:
(optional): --name podman1 runs under unique name podman1. This is handy if you need easy reference to the container
(optional): --rm remove and cleanup container after closing. This is handy if you do not want dangling containers around
--entrypoint="" override image's entrypoint. This is handy to cleanup if the container has custom entrypoint
-it to start interactive session
use the container egel/podman:latest
jump to bash shell
sh
docker run --name podman1 --rm --entrypoint="" -it egel/podman:latest bash
