Recommended master configurations
You can select the master configuration when creating or updating a cluster. For stable operation, the master configuration must match the cluster workload.
Use the table to select the minimum master configuration based on your cluster parameters. Configurations may change; see the list of available configurations.
The selected configuration sets the minimum resource values for the master. If master autoscaling is enabled in the cluster, the selected configuration is used as the lower scaling boundary.
