What's the Jenkins Operator?

Jenkins operator is a Kubernetes native operator which fully manages Jenkins on Kubernetes. It was built with immutability and declarative configuration as code in mind.

Out of the box it provides:

• integration with Kubernetes (Jenkins kubernetes-plugin)
• pipelines as code (Jenkins pipelines)
• extensibility via groovy scripts (similar to Jenkins script console) or (configuration as code plugin)
• secure defaults and hardening (see the security section of the documentation)

Problem statement and goals

The main reason why we decided to implement the Jenkins Operator is the fact that we faced a lot of problems with standard Jenkins deployment. We want to make Jenkins more robust, suitable for dynamic and multi-tenant environments.

Some of the problems we want to solve:

• installing plugins with incompatible versions or security vulnerabilities
• better configuration as code
• security and hardening out of the box
• make errors more visible for end users
• backup and restore for jobs history
• orphaned jobs with no JNLP connection
• handle graceful shutdown properly
• proper end to end tests for Jenkins lifecycle
