Modifying Cluster Specifications

Updated on 2024-10-22 GMT+08:00

Function

This API is used to modify the specifications of a specified cluster.

NOTE:
  • The URL for cluster management is in the format of https://Endpoint/uri, where uri indicates the resource path for API access.

URI

POST /api/v3/projects/{project_id}/clusters/{cluster_id}/operation/resize

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

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.

Request Parameters

Table 2 Request header parameters

Parameter

Mandatory

Type

Description

Content-Type

Yes

String

Message body type (format).

X-Auth-Token

Yes

String

Requests for calling an API can be authenticated using either a token or AK/SK. If token-based authentication is used, this parameter is mandatory and must be set to a user token. For details, see Obtaining a User Token.

Table 3 Request body parameters

Parameter

Mandatory

Type

Description

flavorResize

Yes

String

The target flavor to be changed. You can only adjust the maximum number of worker nodes in a cluster. The number of master nodes is fixed and cannot be altered, and the cluster flavors cannot be downgraded. Suppose the original cluster flavor is cce.s2.medium. In that case, you can only upgrade it to cce.s2.large or higher, but you cannot downgrade it to cce.s2.small or cce.s1.medium.

  • 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 three master nodes and a maximum of 50 worker nodes
  • cce.s2.medium: a medium-scale CCE cluster with three master nodes and a maximum of 200 worker nodes
  • cce.s2.large: a large-scale CCE cluster with three master nodes and a maximum of 1,000 worker nodes
  • cce.s2.xlarge: an ultra-large-scale CCE cluster with three master nodes and a maximum of 2,000 worker nodes
NOTE:

The fields in the parameters are described as follows:

  • s1: specifies a cluster with one master node. If the master node is faulty, the cluster will become unavailable, but running workloads in the cluster are not affected.
  • s2: specifies an HA cluster with three master nodes. If one of the master nodes is faulty, the cluster is still available.
  • small: specifies that a cluster can manage a maximum of 50 worker nodes.
  • medium: specifies that a cluster can manage a maximum of 200 worker nodes.
  • large: specifies that a cluster can manage a maximum of 1,000 worker nodes.
  • xlarge: specifies that a cluster can manage a maximum of 2,000 worker nodes.
