For me it was a cherry on top of my home built pipeline. I was able to learn the general cert usage through setting up my CI/CD. It was fun and costed me nothing.
Samesies. I'm glad someone else considers home built pipelines a fun hobby as well.
What does your pipeline look like? I've always wanted to do this but a lot of CD systems are so heavy. Great at work but super overkill for a homelab.
Gitlab for CI, Nexus for jars and docker containers and routing traffic with traefik.
Its super easy if you setup them using docker. I will move to jenkins CI tough. Its plugin/ecosystem brings you much more value over gitlab.
