Kubernetes versions

HAPTIC requires Kubernetes 1.35 or newer, the oldest release the Kubernetes project still maintains. Helm rejects clusters below the chart's kubeVersion requirement.

Tested versions

Kubernetes Coverage
1.35 Minimum supported version; routing, admission, upgrades, installation without Gateway API CRDs, and graceful shutdown
1.37 The same checks, plus every supported HAProxy series

Kubernetes 1.36 meets the chart's version requirement but doesn't have separate test runs. For supported proxy versions, see HAProxy versions.
