## Rootful Podman in rootful Podman with --privileged
podman run --privileged quay.io/podman/stable podman run ubi8 echo hello

## added volume
podman run --privileged -v ./mycontainers:/var/lib/containers quay.io/podman/stable podman run ubi8 echo hello

## Rootless Podman in rootful Podman with --privileged
podman run --user podman --privileged quay.io/podman/stable podman run ubi8 echo hello

## Rootful Podman in rootful Podman without --privileged
podman run --cap-add=sys_admin,mknod --device=/dev/fuse --security-opt label=disable quay.io/podman/stable podman run ubi8-minimal echo hello

## Run podman inside podman and check podman version
$ podman run --privileged \

  podman version

## Run podman inside podman and using ubi8 image inside.
$ podman run --privileged \
  quay.io/podman/stable \
  podman run ubi8 echo hello
