PackagesKubernetes WordPress Helm Chart
In this tutorial, we’ll use the Helm API of @pulumi/kubernetes to deploy v9.6.0 of the Wordpress
Helm Chart to a Kubernetes cluster. Pulumi will expand the Helm Chart and submit the expanded YAML to the cluster.
Running the App
Start by downloading the example code.
If you haven’t already, follow the steps in Pulumi Installation and Setup and Configuring Pulumi Kubernetes to get set up with Pulumi and Kubernetes.
Now, install dependencies:
$ npm install
Create a new stack:
$ pulumi stack init
Enter a stack name: wordpress-dev
Preview the deployment of the application.
Preview the deployment of the application and then perform the deployment:
pulumi up

We can see here in the ---outputs:--- section that Wordpress was allocated a public IP, in this
case 35.193.210.254. It is exported with a stack output variable, frontendIp. We can use curl
and grep to retrieve the <title> of the site the proxy points at.
$ curl -sL $(pulumi stack output frontendIp):80 | grep "<title>"
<title>User's Blog! – Just another WordPress site</title>
You can also navigate to the site in a web browser.
When you’re done, you can remove these resources with pulumi destroy:
pulumi destroy --skip-preview
