Source-backed version compatibility
Rancher Ack version compatibility. The Rancher 2.15.2 matrix certifies RKE2, K3s, AKS, EKS, GKE, and ACK Kubernetes 1.34 through 1.36 for provisioned or imported downstream clusters.
Quick answer
Supported and tested versions have compatibility evidence. Recommended and bundled versions describe upstream choices without establishing compatibility. Versions outside the documented coverage are unknown, not necessarily incompatible.
