Source Code

Longhorn is 100% open source software. Project source code is spread across a number of repos:

  1. Longhorn Engine -- Core controller/replica logic https://github.com/longhorn/longhorn-engine
  2. Longhorn Instance Manager -- Controller/replica instance lifecycle management https://github.com/longhorn/longhorn-instance-manager
  3. Longhorn Share Manager -- NFS provisioner that exposes Longhorn volumes as ReadWriteMany volumes. https://github.com/longhorn/longhorn-share-manager
  4. Backing Image Manager -- Backing image file lifecycle management. https://github.com/longhorn/backing-image-manager
  5. Longhorn Manager -- Longhorn orchestration, includes CSI driver for Kubernetes https://github.com/longhorn/longhorn-manager
  6. Longhorn UI -- Dashboard https://github.com/longhorn/longhorn-ui

Prerequisites

  1. A container runtime compatible with Kubernetes (Docker v1.13+, containerd v1.3.7+, etc.)
  2. Kubernetes v1.18+
  3. Make sure bash, curl, findmnt, grep, awk and blkid has been installed in all nodes of the Kubernetes cluster.
  4. Make sure open-iscsi has been installed, and the iscsid daemon is running on all nodes of the Kubernetes cluster. For GKE, recommended Ubuntu as guest OS image since it contains open-iscsi already.
