Some examples I'm making while getting started with k8s on ProxMox
I like playing with WordPress as an onboarding-level project for clusters, because it requires pod networking, dynamic storage, and an externally-accessible service in order to work properly. It's more complicated than a generic nginx setup and forces you to troubleshoot.
Example configuration of deploying an NFS Client Provisioner to your custom k8s cluster
Manifest files from the official wordpress kubernetes documentation. Deploys an ANCIENT (and probably vulnerable) WordPress instance.
My example configuration of a high-avaiable, database-replicated WordPress deployment that's pretty much enterprise-ready.
