Cozystack Is Certified Kubernetes: v1.35 and v1.34 in the CNCF Conformance Record

Cozystack is Certified Kubernetes — conformance results for Kubernetes v1.31 to v1.35

Cozystack is now listed as a Certified Kubernetes distribution. The conformance results for Kubernetes v1.35 and v1.34 are accepted and published in the CNCF conformance repository, at v1.35/cozystack and v1.34/cozystack.

The tested artifact is the tenant Kubernetes cluster a user creates from the catalog. Clusters on five releases, from v1.31 to v1.35, ran the full suite with Sonobuoy in certified-conformance mode on a Cozystack v1.6.1 installation, and every run finished with zero failed tests.

Conformance answers the question every evaluation starts with: is this real Kubernetes? A conformant cluster runs standard manifests, Helm charts and operators without a vendor dialect. Passing on older releases matters too — when migrating from an existing platform, you can move onto Cozystack at the Kubernetes version you run today and upgrade later on your own schedule.

Hikube, a hosted platform built on Cozystack, holds its own CNCF listings for v1.35, v1.34 and v1.33.

The full results and methodology are on the Kubernetes Conformance page.
