Changing Kubernetes service parameters

You can change such Kubernetes parameters as the size and storage policy of the system volume on master nodes. The system volume is used by the Kubernetes management services and etcd. The new parameters will be applied only 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 then click Done.
