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
pipelines as code
extensibility via groovy scripts or configuration as code plugin
security and hardening

Problem statement and goals

The main reason why we decided to write 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:

volumes handling (AWS EBS volume attach/detach issue when using PVC)
installing plugins with incompatible versions or security vulnerabilities
better configuration as code
lack of end to end tests
handle graceful shutdown properly
security and hardening out of the box
orphaned jobs with no jnlp connection
make errors more visible for end users
backup and restore for jobs history
