Updated on 2026-09-08 GMT+08:00

Rotating a Cluster Certificate of a User

Function

This API is used to rotate the certificate of a cluster.

Only clusters of v1.19 or later are supported.

After the operation completes, the certificate for the cluster component is renewed with a new five-year validity period.

Calling Method

For details, see Calling APIs.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

  • If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
  • If you are using identity policy-based authorization, the following identity policy-based permissions are required.

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Details:

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

Constraints:

None

Options:

Project IDs of the account

Default value:

N/A

cluster_id

Yes

String

Details:

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

Constraints:

None

Options:

Cluster IDs

Default value:

N/A

Request Parameters

Table 2 Request header parameters

Parameter

Mandatory

Type

Description

Content-Type

Yes

String

Definition:

Type (or format) of the request body. The default value is application/json. Other values of this field will be provided for specific APIs, if any.

Constraints:

GET requests are not validated.

Range:

N/A

Default Value:

N/A

X-Auth-Token

Yes

String

Details:

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.

Constraints:

None

Options:

N/A

Default value:

N/A

Table 3 Request body parameters

Parameter

Mandatory

Type

Description

component

Yes

String

Definition

Name of a component to be rotated

Constraints

N/A

Range

  • all: The CCE cluster certificate is rotated.

  • service-account-controller: The ServiceAccount-token signing certificate is rotated.

  • custom: The custom certificate is rotated. If this parameter is specified, the certContent parameter must also be specified.

Default Value

N/A

certificateExpirationTime

No

Integer

Definition

The length of time the old ServiceAccount-token signing certificate remains valid after the certificate is rotated.

To ensure that the old ServiceAccount-token signing certificate continue to pass signature verification after rotation, CCE retains the old certificate for a period of time. The rules are as follows:

  • For the first rotation, CCE retains the certificate generated during cluster creation.

  • For the second rotation and subsequent rotations, CCE retains the old certificate for a period of time (24 hours by default). You can configure the retention period using this parameter.

Constraints

N/A

Range

0–8784 (hours)

Default Value

24 (hours)

certContent

No

AuthenticatingProxy object

Definition

Certificate details

Constraints

This parameter is mandatory when component is set to custom.

Table 4 AuthenticatingProxy

Parameter

Mandatory

Type

Description

ca

No

String

Details:

X509 CA certificate (Base64-encoded) configured in authenticating_proxy mode

Constraints:

This field is mandatory when the cluster authentication mode is authenticating_proxy.

Options:

Maximum size: 1 MB

Default value:

N/A

cert

No

String

Details:

Client certificate issued by the X509 CA certificate configured in authenticating_proxy mode, which is used for authentication from kube-apiserver to the extended API server. (The value must be Base64-encoded.)

Constraints:

This field is mandatory when the cluster authentication mode is authenticating_proxy.

Options:

Maximum size: 1 MB

Default value:

N/A

privateKey

No

String

Details:

Private key of the client certificate issued by the X509 CA certificate configured in authenticating_proxy mode, which is used for authentication from kube-apiserver to the extended API server. The private key used by the Kubernetes cluster does not support password encryption. Use an unencrypted private key. (The value must be Base64-encoded.)

Constraints:

This field is mandatory when the cluster authentication mode is authenticating_proxy.

Options:

Maximum size: 1 MB

Default value:

N/A
