Kubernetes The Hard Way

You might've solved this challenge way sooner than I attempted it. Still, I always wanted to go through the process as it has many angles and learning the details intrigues me.

  • Vagrant & VirtualBox: For the nodes of the cluster
  • Ansible: For configuring everything until the cluster is ready
  • Cilium: For the network CNI and as a replacement for the kube-proxy

So, here is my story and how I solved the famous Kubernetes The Hard Way by the great Kelsey Hightower. Stick around if you're interested in the details.
