Jenkins Operator
What's the Jenkins Operator?
The Jenkins Operator is a Kubernetes Native Operator which manages operations for Jenkins on Kubernetes. It has been built with Immutability and declarative Configuration as Code in mind.
Preliminaries
Considering that this Operator is created for managing instances for Jenkins, it is important to understand what
- Jenkins Pipelines and
- CasC (Configuration as Code) are.
Jenkins Pipelines use Scripts written in Groovy which aid in the CasC aspect of Jenkins.
Jenkins uses plugins like CasC to extend it's solution space by carrying out Jobs of different kinds and providing a composable infrastructure for your CI/CD.
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
