These are mostly just formatting/style changes. I'd suggest that if we are going to update it then we should make it significantly easier to read and manage. What we've got now is a gnarly mess of escaping and quotes. We could improve it by changing the commands to follow a form along the lines of

service-0:
  entrypoint:
    - bash
    - -ec
  command: |
    echo "Now we don't need to escape or use && as much";
    tail -f /dev/null
