kubernetes-ts-jenkins

Continuous Integration with Jenkins

This example deploys a container running the Jenkins continuous integration system onto a running Kubernetes cluster using Pulumi and @pulumi/kubernetes.

Running the App

Follow the steps in Pulumi Installation and Setup and Configuring Pulumi Kubernetes to get setup with Pulumi and Kubernetes.

Note: The code in this repo assumes you are deploying to a cluster that supports the LoadBalancer service type. This includes most cloud providers as well as Docker for Mac Edge w/ Kubernetes. If not (for example if you are targeting minikube or your own custom Kubernetes cluster), replace type: "LoadBalancer" with type: "ClusterIP" in jenkins.ts. See the Kubernetes Services docs for more details.

Install dependencies:

$ npm install

Create a new stack:

$ pulumi stack init
Enter a stack name: kubernetes-ts-jenkins-dev

Create configuration keys for the root username and password for the Jenkins instance we are about to create:

$ pulumi config set username <your desired username>
$ pulumi config set password <your desired password> --secret

The deployment is complete! Use kubectl to see the Service that we just deployed:

$ kubectl get services
NAME         TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)                      AGE
jenkins      LoadBalancer   10.43.241.251   35.230.56.127   80:30638/TCP,443:30204/TCP   3m

The Jenkins instance we just deployed is reachable through port 80 of the external IP address. You can now visit http://35.230.56.127/jenkins/login in a Web browser to begin the first-install flow for your new Jenkins instance. You can use the username and password that you saved in your Pulumi config to log in to your new Jenkins instance.

Note: If you are deploying to a cluster that does not support type: "LoadBalancer", and deployed the example using type: "ClusterIP" instead, run kubectl port-forward svc/jenkins 8080:80 to forward the cluster port to the local machine and access the service via localhost:8080.

When you're ready to be done with Jenkins, you can destroy the instance:

$ pulumi destroy
Do you want to perform this destroy? yes
