User Option in Entrypoint

[stephancasas]

Is there any reason why the user needs to be specified in the entrypoint? I could not get this running in Docker Desktop without overriding, dropping the -u flag, and running named as root inside the container.

No, there's no specific reason. I just didn't want the process to run as root.

But I can switch and use USER and ARG.
Ex :

ARG  user=named

USER ${user}
