Day 0 - Bootstrap MacOS with Ansible

After factory resetting the maching you will need to do the following things to bootstrap it with Ansible.

• Set default shell to bash chsh -s /bin/bash (optional)
• Open the App Store and sign in (but do not install anything)
• Install command line tools
  • xcode-select --install
• Add Python 3.8 to the $PATH
• export PATH="$HOME/Library/Python/3.8/bin:$PATH"

Getting a shell on each node

I run several K8S cluster on EKS and by default do not setup inbound SSH to the nodes. Sometimes I need to get into each node to check things or run a one-off tool.

Rather than update my terraform, rebuild the launch templates and redeploy brand new nodes, I decided to use kubernetes to access each node directly.

Signing VirtualBox Kernel Modules

These are the steps I followed enable VirtualBox on my laptop without disabling UEFI Secure Boot. They're nearly identical to the process described on [Øyvind Stegard's blog][blog], save for a few key details. The images here are borrowed from the [Systemtap UEFI Secure Boot Wiki][systemtap].

1. Install the VirtualBox package (this might be different for your platform).
