Scope of Support
A Longhorn support entitlement includes Longhorn components and the following operating systems and platform architectures. Furthermore, Longhorn is supported to run on any certified Kubernetes distributions and versions, such as the actively supported versions of RKE2 and K3s. Experimental or Preview features are not eligible for support.
Longhorn & Rancher Support Matrix
Rancher is an open-source multi-cluster management platform. Longhorn will be supported for management through the Rancher Application Marketplace. For each version, it could be shipped together with a specific Rancher version or delivered through an out-of-band release and available for all actively supported Rancher versions.
| Longhorn Version | Rancher Version |
|---|---|
| v1.4.0-v1.4.4 | v2.7 |
Verified Operating Systems
The following Linux OS distributions and versions have been verified during release testing. However, this does not imply that Longhorn exclusively supports these distributions. Essentially, Longhorn should function well on any certified Kubernetes cluster running on Linux nodes with a wide range of general-purpose operating systems, as well as verified container-optimized operating systems like SLE Micro.
| OPERATING SYSTEM | VERIFIED VERSIONS |
