Before you can interact with the Drupal site on the Pi Cluster, you need to set up your local workstation’s hosts file so you can enter the web address http://cluster.pidramble.test/ in your browser and load the site. You will need to add the following line to the end of your hosts file:
10.0.1.62 cluster.pidramble.test
Instructions: edit your hosts file.
Once you save the new version of the hosts file, go visit http://cluster.pidramble.test/. You should be redirected to the default Drupal site's installer.
Note: You can actually point the domain
cluster.pidramble.testat any one of the Kubernetes nodes (.62,.63, or.64); they are all running an instance of the Traefik ingress controller. In a production environment, you should either use DNS round-robin to point your domain at all the nodes, or use a load balancer sitting in front of the cluster pointed at all the nodes (for a working example using another Pi, see Using Drupal Pi as a load balancer for Pi Dramble).
Install Drupal
The easiest way to install Drupal is to use the installation wizard UI that you see when you access http://cluster.pidramble.test/
Deploy your own Drupal codebase
Deploying your own Drupal codebase and site to the Pi Dramble cluster is fairly easy, though a bit different from a traditional Drupal deployment process (since it runs on Kubernetes and Docker).
For a thorough walkthrough, and a complete example Drupal 9 site—in fact, the very website you're currently reading!—please have a look at the Drupal Example Site for Kubernetes documentation.
