Jenkins as Code

I saw a couple of talks last week, and learned about several ways of automating Jenkins CI.

The problem being solved is: if you automate your builds and tests, why still click the Jenkins web UI by hand? Script it instead.

Jenkins Job DSL, which is based on Groovy (a JVM language). Another topic was Jenkins Pipeline which helps managing many jobs that depend on each other.

In Test Driven Infrastructure, Yury Tsarev presents, among many other things, Jenkins Job Builder. JJB takes descriptions written in YAML or JSON and translates them to Jenkins API with Python.
