Recommended master configurations
You can select master configuration when creating or updating your cluster. For stable operation, make sure the master configuration matches the workload of your Kubernetes cluster.
You can use this table to find the minimum master configuration based on your specific cluster specifications. Configurations may change over time. You can view the list of available configurations here.
The selected configuration allocates minimum resources to the master. If you enable master node auto-scaling in your cluster, your selected configuration will serve as the lower scaling limit.
Warning
Starting June 18, 2026, master node auto-scaling will be enabled on all clusters in the RAPID release channel where the master is deployed in a highly available configuration.
