Hosting WordPress on Kubernetes is not an easy topic, and while we try to cover every aspect in great detail, there are quite a few things we expect you to already be familiar with to some extent:
- A good understanding of WordPress, what themes and plugins are, what wp-config.php is.
- Some experience working in the command line: SSH, curl/wget and basic text editing.
- Some experience with Linux servers: using a package manager, editing config files, restarting services, etc. Most of our tutorial is based on Debian-family distributions, Ubuntu in particular, but any other distro will work just fine.
- A good understanding of Linux containers (Docker, Podman, etc.) – we’ll mostly be using official images from Docker Hub, run under containerd in our clusters, but we might build a few of our own too!
- A basic understanding of PHP, which comes in handy when setting up HyperDB and other WordPress internals.
- Some experience working with relational databases (MySQL, MariaDB). Some admin experience may be useful, but we’ll be covering setting up database replication from scratch anyway.
- A general understanding of YAML, which we’ll use a lot when defining and configuring resources in Kubernetes.
- A few machines to build a cluster on: cloud VMs, local virtual machines or bare metal. We’ll cover the specifics when we create our cluster.
Quite a list for sure! But don’t give up if you’re missing a few of these. They are generally quite easy to learn both in isolation and on the job. If you get stuck or overwhelmed though, we do recommend taking a step back or asking for help.
Good luck!
