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 deployment guide, we will be effortlessly installing the core Rancher Stack, including Rancher Kubernetes, Rancher Multi-Cluster Manger, Longhorn, and NeuVector. In about 15 minutes, we will have a three-node Kubernetes Cluster (RKE2), with lifecycle management (Rancher Manager), persistent storage (Longhorn), and cluster security (NeuVector).
