Containers not running as root (Informational)

Dockerfile images that contain something of the following so within the container is run as non root user:
RUN adduser -u 5678 --disabled-password --gecos "" appuser && chown -R appuser /app

This will cause the kerberos client inside the container to not have access to the TGT created on the host by credentials-fetcher.

The issue names Dockerfile images that create a non-root appuser, but no repository file, test, entry point, or requested change. First clarify the expected behavior for non-root containers, then reproduce whether the Kerberos client can access the host-created TGT and define verification criteria.
