| # main goals: | |
| # - build spring's petclinic project with a few additions for observability and push it as a custom docker image | |
| # - make sure the docker compose file in this repo starts up correctly | |
| # - some steps to sign the built image have been deactivated. This was just copy pasted but seems interesting | |
