What I find hardest about CI offerings is that each one has a unique DSL that inevitably has edge cases that you may only find out once you’ve tried it.

You might face that many times using Gitlab CI. Random things don’t work the way you think it should and the worst part is you must learn their stupid custom DSL.

Not only that, there’s no way to debug the maze of CI pipelines but I imagine it’s a hard thing to achieve. How would I be able to locally run CI that also interacts with other projects CI like calling downstream pipelines?
