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:
Component | Name and version |
---|---|
Underlying OS | Fedora 34 CoreOS |
Container runtime | Docker 20.10.6 |
Network plugin | Flannel with VXLAN |
Limitations
- Kubernetes versions 1.15.x and 1.18.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 rotate
command, as described in the OpenStack documentation.
