Your CI/CD pipeline deploys 15 times a day. It also has zero tests. Every deploy is a coin flip. You find out about bugs when customers tweet angry messages at your company. This is not DevOps — this is chaos with automation.

Your Git log reads like a diary written by someone having a breakdown: "fix stuff", "WIP", "please work", "final final v2", "asdfjkl". If your future self (or your teammates) cannot understand what happened from reading git log --oneline, you are doing version control wrong.

Jenkins has been around since 2011 (as Hudson since 2004) and it runs over 50% of CI/CD pipelines worldwide. Some people say it is old and clunky. They are partially right. But Jenkins is also incredibly powerful, endlessly extensible, and — unlike SaaS alternatives — you own every piece of it.
