Jenkins: K8S

Saksham

Deploying Jenkins on K8S cluster is as simple as

Add Repo

helm repo add jenkins https://charts.jenkins.io
helm repo update

Deploy instance

helm upgrade --install myjenkins jenkins/jenkins -n jenkins --create-namespace

On my local machine the output is as under

Release "myjenkins" does not exist. Installing it now.
