This section is about installations of Rancher server in an air gapped environment. An air gapped environment could be where Rancher server will be installed offline, behind a firewall, or behind a proxy.

The installation steps differ depending on whether Rancher is installed on an RKE Kubernetes cluster, a K3s Kubernetes cluster, or a single Docker container.
