Jenkins

Jenkins is a pluggable continuous integration system. The Google team is running a Jenkins server on a private GCE instance for the Kubernetes project in order to run longer integration tests, continuously, on different providers. Currently, we (Google) are only running Jenkins on our own providers (GCE and GKE) in different flavors.

General flow

The flow of the Google Jenkins server:

  • Under the kubernetes-build job: Every 5 minutes, Jenkins polls for a batch of new commits, after which it runs the build.sh script (in this directory) on the latest tip. This results in build assets getting pushed to GCS and the latest.txt file in the ci bucket being updated. That job then triggers kubernetes-e2e-*.
  • On trigger, and every half hour (which effectively means all the time, unless we're failing cluster creation), e2e variants run, on the latest build assets in GCS:
    • kubernetes-e2e-gce: Standard GCE e2e
    • kubernetes-e2e-gke: GKE provider e2e, with head k8s client and GKE creating clusters at its default version
    • kubernetes-e2e-gke-ci: GKE provider e2e, with head k8s client and GKE creating clusters at the head k8s version
  • Each job will not run concurrently with itself, so, for instance, Jenkins executor will only ever run one kubernetes-build job. However, it may run the jobs in parallel, i.e. kubernetes-build may be run at the same time as kubernetes-e2e-gce. For this reason, you may see your changes pushed to our GCS bucket rapidly, but they may take some time to fully work through Jenkins. Or you may get lucky and catch the train in 5 minutes.

Scripts

The scripts in this directory are directly used by Jenkins, either by curl from githubusercontent (if we don't have a git checkout handy) or by executing it from the git checkout. Since Jenkins is an entity outside this repository, it's tricky to keep documentation for it up to date quickly. However, the scripts themselves attempt to provide color for the configuration(s) that each script runs in.
