Install as a Rancher Apps & Marketplace

Run Longhorn on Kubernetes with Rancher 2.x

One benefit of installing Longhorn through Rancher Apps & Marketplace is that Rancher provides authentication to the Longhorn UI.

If there is a new version of Longhorn available, you will see an Upgrade Available sign on the Apps & Marketplace screen. You can click Upgrade button to upgrade Longhorn manager. See more about upgrade here.

Prerequisites
