Yes

String

Project ID. For details about how to obtain the value, see How to Obtain Parameters in the API URI.

cluster_id

Yes

String

Cluster ID. For details about how to obtain the value, see How to Obtain Parameters in the API URI.

Table 3 Request body parameters

Parameter

Mandatory

Type

Description

flavorResize

Yes

String

Target specifications:

  • cce.s1.small: a small-scale CCE cluster with one master node and a maximum of 50 worker nodes

  • cce.s1.medium: a medium-scale CCE cluster with one master node and a maximum of 200 worker nodes

  • cce.s2.small: a small-scale CCE cluster with multiple master nodes and a maximum of 50 worker nodes

  • cce.s2.medium: a medium-scale CCE cluster with multiple master nodes and a maximum of 200 nodes

  • cce.s2.large: a large-scale CCE cluster with multiple master nodes and a maximum of 1,000 worker nodes

  • cce.s2.xlarge: an ultra-large-scale CCE cluster with multiple master nodes and a maximum of 2,000 nodes

NOTE:

  • s1: indicates a CCE cluster with one master node.

  • s2: indicates a CCE cluster with multiple master nodes.

  • dec: indicates a dedicated CCE cluster. For example, cce.dec.s1.small indicates a small-scale dedicated CCE cluster with one master node and a maximum of 50 worker nodes.

  • Maximum number of nodes: indicates the maximum number of worker nodes that can be managed by the cluster. Select a node scale based on your requirements.

  • A cluster with one master node: If the master node is faulty, the cluster will become unavailable, but the running workloads will not be affected.

  • A cluster with multiple master nodes: This is an HA cluster. If a master node is faulty, the cluster can still be functionally available.

extendParam

No
