### Docker Installations
The [single-node Docker installation]({{<baseurl>}}/rancher/v2.x/en/installation/other-installation-methods/single-node-docker) is for Rancher users that are wanting to test out Rancher. Instead of running on a Kubernetes cluster using Helm, you install the Rancher server component on a single node using a `docker run` command.
Since there is only one node and a single Docker container, if the node goes down, there is no copy of the etcd data available on other nodes and you will lose all the data of your Rancher server.
### Air Gapped Installations
Follow [these steps]({{<baseurl>}}/rancher/v2.x/en/installation/other-installation-methods/air-gap) to install the 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.

When the Rancher server is installed with Docker, it cannot be migrated to a Kubernetes cluster for a production environment.

Rancher can be installed by running a single Docker container.
In this installation scenario, you'll install Docker on a single Linux host, and then deploy Rancher on your host using a single Docker container.
