Kubernetes v4.5.5 published on Wednesday, Nov 15, 2023 by Pulumi

    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.

    wordpress

    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
    Previewing update (wordpress-dev)

    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&#039;s Blog! &#8211; 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
