Table 2. Request parameters
Parameter Type Required Description
count int Yes The number of worker nodes that you want to add.
worker_instance_type string Yes The ENS instance type of worker nodes.
ens_region_id string Yes The region ID of the ENS instances.
worker_image_id string Yes The operating system image used by worker nodes.
ens_internet_charge_type string Yes The billing method of the ENS instances. This parameter is required if you purchase ENS instances for the first time. If you have existing ENS instances, the current billing method is used. Valid values:
  • BandwidthByDay: Pay by the daily peak bandwidth.
  • 95BandwidthByMonth: Pay by the monthly 95th percentile bandwidth.
worker_period int Yes The subscription duration of worker nodes. Unit: months. Valid values: 1, 2, 3, 4, 5, 6, 7, 8, 9, and 12.
login_password string Yes The password for logging on to worker nodes.
worker_system_disk_size int Yes The system disk size of a worker node. Unit: GiB. The value must be a multiple of 10 from 20 to 100. The system disk size must be greater than the size of the operating system image.
is_edge_worker bool Yes Set the value to true.
worker_data_disk_size int No The size of a data disk. If data disks are not required, set the value to 0. If data disks are required, set the value to a multiple of 10 from 20 to 200.
worker_auto_renew bool No Specifies whether to enable auto renewal for worker nodes. Valid values:
  • true: enables auto renewal.
  • false: disables auto renewal.

Default value: false.
worker_auto_renew_period int No The auto renewal period of worker nodes. This parameter is required if worker_auto_renew is set to true. Valid values: 1 to 12.
timeout_mins int No The time-out duration.
