Required Kubernetes Programs

First, install some required programs:

homebrew - always install Homebrew first!
keybase - used to cryptographically validate the Terraform package
- macOS: brew install --cask keybase
- Install it, open it and configure it.
- Leave keybase running during the Terraform install
Terraform
- via tfenv; brew install tfenv quickstart
IntelliJ Community Edition
- macOS: brew install intellij-idea-ce
  - install the Terraform plugin
  - Preferences > Plugins > Search: Terraform and HCL
  - Install this plugin and restart IntelliJ
helm 3.x
- macOS: brew install kubernetes-helm
- Debian/Ubuntu
K9S Dashboard

There are many more than this but these are a good foundation.
