Running slaves in Kubernetes

The following example runs a Jenkins Master using docker-compose and uses Minikube to run slaves within it.

Running the example will:

• Run the Jenkins master
• Configure Jenkins with the following:
  • jenkins_database realm (user: admin, password: admin)
  • certificate credential: minikube-cert that will enable Jenkins connect with the Minikube cluster
  • kubernetes cloud: kube-cloud with jenkinsci/jnlp-slave:latest slave template
  • maven installer: MVN-3.5.0 that will be installed on every slave when needed
  • Seed Job: seed-job that will create a sample-job using jobDSL

Prerequisites

• docker-compose is installed

• Minikube installed - https://kubernetes.io/docs/getting-started-guides/minikube/#installation

• Make sure minikube is started

$ minikube start

Running the example

In order to run the example

$ # Clone the repository
$ git clone https://github.com/odavid/my-bloody-jenkins.git
$ cd my-bloody-jenkins/examples/kubernetes
$ # setup variables to be used by docker-compose
$ . ./setup-env
$ # run the docker-compose
$ docker-compose up -d
$ # view logs
$ docker-compose logs -f

Wait until you'll see:

INFO: Jenkins is fully up and running

Open the browser:

open http://localhost:8080/

You should see the seed job running and waiting for a kubernetes slave to be started. Please be patient, pulling the jenkinsci/jnlp-slave:latest may take a while.
