Deploy Jenkins	Deploy Jenkins	1	2021-01-25	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
  namespace: default

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.
