#min_num_instances ⇒ ::Integer

Returns Optional. The minimum number of primary worker instances to create. If min_num_instances is set, cluster creation will succeed if the number of primary workers created is at least equal to the min_num_instances number.

Example: Cluster creation request with num_instances = 5 and min_num_instances = 3:

  • If 4 VMs are created and 1 instance fails, the failed VM is deleted. The cluster is resized to 4 instances and placed in a RUNNING state.
  • If 2 instances are created and 3 instances fail, the cluster in placed in an ERROR state. The failed VMs are not deleted.

Returns:

  • (::Integer) —

    Optional. The minimum number of primary worker instances to create. If min_num_instances is set, cluster creation will succeed if the number of primary workers created is at least equal to the min_num_instances number.

    Example: Cluster creation request with num_instances = 5 and min_num_instances = 3:

    • If 4 VMs are created and 1 instance fails, the failed VM is deleted. The cluster is resized to 4 instances and placed in a RUNNING state.
    • If 2 instances are created and 3 instances fail, the cluster in placed in an ERROR state. The failed VMs are not deleted.
