How do I install PHP extensions from the Wordpress Kubernetes Marketplace app?

So far I’ve been able to set up a Kubernetes cluster with the Wordpress Kubernetes app. It comes with a load balancer, droplet pool, and some volumes. After getting it set up, I was able to switch to the wordpress namespace with kubectl.

kubectl config set-context --current --namespace=wordpress

Then I executed bash on the wordpress pod.

kubectl exec -it wordpress-pod-name -- /bin/bash

So I did some exploring and found that the bitnami installation for wordpress is in /opt/bitnami and /bitnami has wp-content in it for some reason. On bitnami’s documentation, you can use a script called ctlscript.sh to restart the Apache and PHP services.

Install Different PHP Modules

Strangely enough, this script does’t exist and I can’t find it. I tried restarting Apache and PHP the usual ways and those didn’t work either. I wanted to start by installing either ImageMagick or GD for PHP, but without being able to restart the services I’m stuck.
