Building a CI/CD Pipeline Runner from Scratch in Python

Why does air-gapped environment require rolling your own CI/CD solution? Plenty of examples of air-gapped Jenkins and/or Argo Workflows. Was this just an educational exercise?

Jenkins sucks but is insanely reliable

Argo Workflows does not live up to what they advertise, it is so much more complex to setup and then build workflows for. Helm + Argo is pain (both use the same template delimiters...)

Jenkins, like many tools with extreme flexibility, sucks as much as you make it suck. You can pretty easily turn Jenkins into a monstrosity that makes everyone afraid to ever try to update it. On the other hand, you can also have a pretty solid setup that is easy to work on. The trouble is that the tool itself doesn't guide you much to the good path, so unless you've seen a pleasant Jenkins instance before you're likely to have a worse time than necessary.

Are you sure, because last time I used Jenkins it actively sucked. The interface was a total mess and it doesn't surface results in any useful way.

When was the last time you used Jenkins? I don't get the hate. Not only from you, but lots of people on the internet. What makes Jenkins stand out IMO is the community and the core maintainers, they are perhaps moving slow, but they are moving in the right directions. The interface looks really nice now, they've done a lot of ux improvements lately.
