s2i does not update Cmd after assemble with podman service

[lunicon]

Run podman image created with s2i fail with error

podman run --rm -it b2bpartners

tar: Refusing to read archive contents from terminal (missing -f option?)
tar: Error is not recoverable: exiting now

podman inspect --format='{{ json .Config.Cmd }}' b2bpartners

["/bin/sh","-c","tar -C /app/builder -xf - && /app/s2i/assemble"]

Looks like s2i doesnt commit Cmd:[/app/s2i/run] as it show in build log

s2i --loglevel=5 --url=unix:///run/podman/podman.sock build ./build/libs s2i-payara:5.2021.8_J8 localhost/b2bpartners

I tend to believe this is rather podman's bug.

[matejvasek]

This podman's bug could be workaround by changes to pkg/docker/docker.go such that the ENTRYPOINT CMD and maybe some other settings are propagated via Changes options.

Example:

This might be fixed by containers/podman#20657

[nalind]

That is the intent, yes.
