+# A basic EKS cluster
+
+If you're already in the AWS ecosystem, it may make sense for you to deploy your Kubernetes cluster using EKS. 
+
+What follows are notes I made while establishing a very basic cluster to work on [OIDC authentication for EKS](/kubernetes/oidc-authentication/eks-authentik/) using [authentik][k8s/authentik].
+
+## Ingredients
+
+1. AWS CLI tools `awscli` and `eksctl`, configured for your IAM account
+2. Some spare change :moneybag: on your AWS account for a few hours / days of EC2 for the underlying nodepool.
+
+## Preparation
+
+### Create cluster
+
+Creating an EKS cluster is a one-line command. I ran `eksctl create cluster --name funkypenguin-authentik-test --region ap-southeast-2` to create my cluster.
+
+It took 14 minutes to complete :man_facepalming:
+
+### Setup EBS CSI driver
+
+The default storageclass (gp2) didn't work for me, and I like storage based on CSI, so that I can use [Velero][velero] with [csi-snapshotter](/kubernetes/backup/csi-snapshots), so I added the [EBS CSI Driver](/kubernetes/persistence/aws-ebs/). This is optional if you don't care about CSI or persistent storage!
+
+## Summary
+
+Well, I'm done. This is probably the shortest recipe ever (*although 14 min is a comparatively long time, IMO, to deploy a simple cluster*). The links on this page to the various steps (OIDC, storage) will provide more detail on those particular configs.
