# Step 1: build a dummy image with ENTRYPOINT and CMD
container="$(buildah from "docker.io/library/ubuntu:18.04")"
buildah config \
    --entrypoint '["/bin/bash", "-e", "/entrypoint.sh"]' \
    --cmd "/mycommand" \
    "$container"
image="localhost/myuser/myimage:latest"
buildah commit --rm "$container" "$image"
podman tag "$image" "localhost/myuser/myimage:original"

# Step 2: inspect the image (all good here)
podman inspect --format="{{.Config.Entrypoint}}" "$image"      # prints: [/bin/bash -e /entrypoint.sh]
podman inspect --format="{{.Config.Cmd}}" "$image"             # prints: [/mycommand]

# Step 3: make a container from the image
# Note that the ENTRYPOINT gets prepended to the CMD
container="$(podman container create "$image")"
podman inspect --format="{{.Config.Entrypoint}}" "$container"  # prints: /bin/bash -e /entrypoint.sh
podman inspect --format="{{.Config.Cmd}}" "$container"         # prints: [/bin/bash -e /entrypoint.sh /mycommand]
podman commit "$container" "$image"

# Step 4: check the resulting image (the problem persists)
podman inspect --format="{{.Config.Entrypoint}}" "$image"      # prints: [/bin/bash -e /entrypoint.sh]
podman inspect --format="{{.Config.Cmd}}" "$image"             # prints: [/bin/bash -e /entrypoint.sh /mycommand]

# Step 5: repeat step 3, and note that the ENTRYPOINT is prepended again
container="$(podman container create "$image")"
podman inspect --format="{{.Config.Entrypoint}}" "$container"  # prints: /bin/bash -e /entrypoint.sh
podman inspect --format="{{.Config.Cmd}}" "$container"         # prints: [/bin/bash -e /entrypoint.sh /bin/bash -e /entrypoint.sh /mycommand]
podman commit "$container" "$image"

# Step 6: re-inspect, this starts to be a problem
podman inspect --format="{{.Config.Entrypoint}}" "$image"      # prints: [/bin/bash -e /entrypoint.sh]
podman inspect --format="{{.Config.Cmd}}" "$image"             # prints: [/bin/bash -e /entrypoint.sh /bin/bash -e /entrypoint.sh /mycommand]

# Step 7: for comparison, test with buildah (no problem here)
container="$(buildah from "localhost/myuser/myimage:original")"
buildah commit --rm "$container" "$image"
podman inspect --format="{{.Config.Entrypoint}}" "$image"      # prints: [/bin/bash -e /entrypoint.sh]
podman inspect --format="{{.Config.Cmd}}" "$image"             # prints: [/mycommand]
