Let's take a look at a Jenkinsfile.orig which we'll use as a base to generate Jenkinsfile that will contain the correct address of the cluster and the GitHub user.
1 cat Jenkinsfile.orig
The output is too big for us to explore it in one go, so we'll comment on each section separately. The first in line is the options block.

buildDiscarder logRotator(numToKeepStr: '5')

The last successful build of a branch is often the only one that matters. We set them to five just to prove that I'm not cheap. By discarding the old builds, we're ensuring that Jenkins will perform faster...
