Overview and Introduction

In today's highly connected world, we sometimes forget that there are many instances, especially in the government, where environments need to be intentionally isolated from external connectivity, creating what is known as an air-gapped or disconnected environment. In some cases, these environments may have external connectivity, but that connectivity is extremely unreliable or is limited in it's communication, creating what is known as a denied, disrupted, intermittent, and limited impact environment.

In this repo, we're going to cover the creation of a RKE2 cluster into Harvester using an airgapped process (aka Bootstrap!). We'll follow that up by installing Rancher on top of RKE2. We're going to do all of this using Terraform. Terraform allows us to declaratively define our environment in code and then create that environment in a straight-forward (and sustainable) way.

For the better part of a decade, we developers and operators have relied on the Docker Hub and their image repository for our needs. This has been great for the growth of the technology, but this growth has necessitated a change to how Docker makes money. As such, Docker is rate limiting anonymous and authenticated users.
