4.11. Managing Kubernetes Clusters

In Virtuozzo Hybrid Infrastructure, Kubernetes clusters are created by self-service users. To be able to use the service, however, you need to install it in the admin panel. The Kubernetes service can be deployed along with the compute cluster or later (see Creating the Compute Cluster or Managing Add-On Services). The network requirements for Kubernetes clusters are described in Kubernetes Network Requirements.

You can also perform the following actions in the admin panel:

  • view Kubernetes cluster details
  • change Kubernetes service parameters
  • delete Kubernetes clusters

To view the details of a Kubernetes cluster, open COMPUTE > Kubernetes and click a cluster.

You can change such parameters as the size and storage policy of the system volume that is used by the Kubernetes management services and etcd. The new parameters will be applied to system volumes on master nodes in new Kubernetes clusters. System volumes in existing Kubernetes clusters will retain their previous parameters. To improve the stability of Kubernetes clusters, it is highly recommended to select a storage policy with an SSD-based tier.

To change the Kubernetes service parameters, click Settings on the Kubernetes clusters screen, set the desired storage policy and size for the system volume, and click Done.

To delete a Kubernetes cluster, open COMPUTE > Kubernetes, click a cluster, and click Delete on the toolbar.
