2.2 More challenging swaps

Container images - More challenging swaps

Adapt Dockerfile

• switch to apk
• user permission ID no longer root, uid=65532
• images set entrypoint explicitly (in python image the entrypoint is python)
  • ´docker run-it python´
  • ´docker run -it python echo “in a shell”´
• Busy Box as default
• groupadd/useradd -> addgroup, adduser
• entrypoints may be different
