Modifying Cluster Specifications
Function
This API is used to modify the specifications of a cluster.
-
The URL for cluster management is in the format of https://Endpoint/uri, in which uri indicates the resource path, that is, the path for API access.
-
For details about constraints, see Changing Cluster Scale.
Calling Method
For details, see Calling APIs.
URI
POST /api/v3/projects/{project_id}/clusters/{cluster_id}/operation/resize
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
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. |
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.
NOTE:
The fields in the parameters are described as follows:
|
extendParam |
No |
extendParam object |
Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
decMasterFlavor |
No |
String |
Specifications of the master node in the dedicated hybrid cluster |
isAutoPay |
No |
String |
Whether auto payment is enabled.
NOTE:
This field is valid for yearly/monthly clusters. If not specified, auto payment is not enabled. |
Response Parameters
Status code: 201
Parameter |
Type |
Description |
---|---|---|
jobID |
String |
ID of the job |
orderID |
String |
ID of the order for modifying the specifications of a yearly/monthly billed cluster |
