Inspired by @kelseyhightower's Kubernetes The Hard Way, these are just notes from installing Kubernetes for my own purposes (largely, development and research). This, of course, is not intended to be anywhere near production.
This is not a PR to the original because I couldn't quite figure out how to make it make sense in parallel to the all-encompassing original. If anyone has an idea, let me know.
The goal is to focus on being able to experiment with K8S functionality which is the added value and ignore things that are not. For example, security is an issue everywhere, and so it is an orthogonal concern and just gets in the way (I really do not need to spend time on signing certificates and stuff if all I want is to deploy Kubernetes on a few local VMs). Similarly, an issue of operating HA etcd.
The following are the major things that are changed/adopted from the original:
- etcd and master nodes do not need to be HA; a single node will do
- Completely ignore security (no certs, no SSL/TLS/HTTPS)
- Can do with a single node (the master is also a single worker)
- Not limited to GCP, but starting with VMWare Fusion (because that's one piece of my infrastructure).
- Provisioning
- [VMWare Fusion] (this assumes VMWare Fusion Pro 8.5.0 for now)
- This assumes OSX with Kubernetes installed (TBD)
- [VMWare Fusion] (this assumes VMWare Fusion Pro 8.5.0 for now)
