Is Linkerd compatible with Kubernetes 1.37?
Service mesh with a published minimum and maximum Kubernetes version for each Linkerd minor.
Minimum 1.31, maximum 1.35.
The supported-versions table lists Linkerd 2.20 as Kubernetes 1.31 through 1.35, 2.19 as 1.22 through 1.35, and 2.18 as 1.22 through 1.32. The page says Linkerd supports the Kubernetes versions that were supported when that Linkerd version shipped, and that a patch release rarely changes the supported Kubernetes range.
Version grid
| Linkerd | 1.31 | 1.32 | 1.33 | 1.34 | 1.35 | 1.36 | 1.37 |
|---|---|---|---|---|---|---|---|
| 2.20 · current | Supported | Supported | Supported | Supported | Supported | Not supported | Not supported |
| 2.19 | Supported | Supported | Supported | Supported | Supported | Not supported | Not supported |
| 2.18 | Supported | Supported | Not supported | Not supported | Not supported | Not supported | Not supported |
Empty-looking “not in the published matrix” cells were not listed by the project. They are not a guess that the combination fails.
Notes
No GitHub release tag stable-2.20.0 was found on 2026-11-15. The newest release tag is edge-26.11.2. The compatibility table still uses 2.x minors. Edge tags are recorded as latest_release and are not rows in that table. Helm chart name on main is linkerd-control-plane.

Managed Kubernetes end of support
Addon compatibility is not the same as the platform’s support window. End-of-support dates for the managed services are on EOL Radar: Amazon EKS (opens in a new tab), Azure AKS (opens in a new tab), Google Kubernetes Engine (opens in a new tab).
