6. 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 |
Fedora 36 CoreOS |
Docker 20.10.12 |
Flannel with VXLAN |
v1.23.5, v1.24.3 |
containerd 1.6.6 |
Limitations:
Kubernetes versions 1.15.x–1.20.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.
