Managing Kubernetes clusters
Self-service users can deploy ready-to-use Kubernetes clusters with persistent storage for managing containerized applications.
A Kubernetes cluster includes the following components:
| Kubernetes version | Underlying OS | Container runtime | Network plugin |
|---|---|---|---|
| v1.21.3, v1.22.2, v1.23.5 | Fedora 37 CoreOS | Docker 20.10.23 | Flannel with VXLAN |
| v1.24.3 | containerd 1.6.15 |
Limitations
- Kubernetes versions 1.15.x–1.21.x are no longer supported. Kubernetes clusters created with these versions are marked with the Deprecated tag.
- Kubernetes cluster certificates are issued for five years. To renew the certificates, use the
openstack coe ca rotatecommand, as described in the OpenStack documentation.
