"Some operations require root. You may be prompted for your 'sudo' password."

The tool wants to do something as root and that therefore requires sudo to work for the non-root user.

You need to add some additional things to the Dockerfile to enable the APP_USER to use sudo.

If you have added the configuration that makes this work:

RUN sudo echo hello

then the tool should work as well.
