>> CI pipeline? CI is a new acronym to me, Stefan.
Continuous Integration for example automated test builds to keep the code in a state that actually compiles. GitHub provides Travis CI to run tests etc everytime a commit is pushed to the repo. I already have a (rather big) docker image here that compiles the amanda-code. No need to have Debian and gcc on my host-system, all that is capsuled in the docker container spawned for the tests. Nice paradigm shift once you learned the basics. btw I give a talk about GitLab CI/CD this saturday. The problem for most of you is that this will happen in austria ;-)
