Deploy Jenkins

Deploy production ready Jenkins Operator manifest

Once Jenkins Operator is up and running let’s deploy actual Jenkins instance. Create manifest e.g. jenkins_instance.yaml with following data and save it on drive.

apiVersion: jenkins.io/v1alpha2
kind: Jenkins
metadata:
  name: example
spec:
  master:
    containers:
    - name: jenkins-master
      image: jenkins/jenkins:lts
      imagePullPolicy: Always
      livenessProbe:
        failureThreshold: 12
        httpGet:
          path: /login
          port: http
          scheme: HTTP
        initialDelaySeconds: 80
        periodSeconds: 10
        successThreshold: 1
        timeoutSeconds: 5
      readinessProbe:
        failureThreshold: 3
        httpGet:
          path: /login
          port: http
          scheme: HTTP
        initialDelaySeconds: 30
        periodSeconds: 10
        successThreshold: 1
        timeoutSeconds: 1
      resources:
        limits:
          cpu: 1500m
          memory: 3Gi
        requests:
          cpu: "1"
          memory: 500Mi
  seedJobs:
  - id: jenkins-operator
    targets: "cicd/jobs/*.jenkins"
    description: "Jenkins Operator repository"
    repositoryBranch: master
    repositoryUrl: https://github.com/jenkinsci/kubernetes-operator.git

Deploy a Jenkins to Kubernetes:

kubectl create -f jenkins_instance.yaml

Watch the Jenkins instance being created:

kubectl get pods -w

Get the Jenkins credentials:

kubectl get secret jenkins-operator-credentials-<cr_name> -o 'jsonpath={.data.user}' | base64 -d
kubectl get secret jenkins-operator-credentials-<cr_name> -o 'jsonpath={.data.password}' | base64 -d

Connect to the Jenkins instance (minikube):

minikube service jenkins-operator-http-<cr_name> --url

Connect to the Jenkins instance (actual Kubernetes cluster):

kubectl port-forward jenkins-<cr_name> 8080:8080

Then open browser with address http://localhost:8080.
