Supported Distributions

UDS Core runs on any CNCF-conformant Kubernetes distribution that has not reached End-of-Life. The following are actively tested in CI:

Note

UDS Core currently tests against Kubernetes 1.35 across all distributions. The target is typically n-1 (one minor version behind the latest release, latest patch). This version may lag slightly behind new Kubernetes releases.

Distribution	K8s Version	Status	Testing Schedule
K3s / k3d	1.35		Nightly and before each release
Amazon EKS	1.35		Weekly and before each release
Azure AKS	1.35		Weekly and before each release
RKE2 (on AWS)	1.35		Weekly and before each release

Note

Unlisted CNCF-conformant distributions are expected to work but are not validated in CI. Bug reports and contributions for compatibility issues are welcome.
