DescribeClusterKubeconfig

POST

Obtain the cluster kubeconfig file. Different sub-accounts have their own kubeconfig files. The kubeconfig file contains the kube-apiserver client certificate of the corresponding sub-account. By default, the client certificate is created when this API is called for the first time, and the certificate is valid for 20 years with no permissions granted. For the cluster owner or primary account, the cluster-admin permission is granted by default.

Wire call

Converge Cloud is RPC over HTTP. There is one path — / — and the action travels in the X-TC-Action header. The /tke/DescribeClusterKubeconfig path used in the OpenAPI document is a documentation convenience so each action is addressable; it is not a route on the server.

Request parameters

ClusterIdstringYesCluster ID
IsExtranetbooleanNoDefaults to `false`, which means to obtain the kubeconfig of private network

Response

Fields are returned inside the Response envelope. Converge Cloud answers HTTP 200 for errors as well as successes, so read Response.Error rather than the status code — and test for the presence of that object, because Code is occasionally the empty string.

FieldTypeDescription
KubeconfigstringSub-account kubeconfig file can be used to access the cluster kube-apiserver directly (if the "IsExtranet" parameter is false, it returns the kubeconfig for private network access, and the server will be a default domain name if the private network is not enabled; if the "IsExtranet" parameter is true, it returns the kubeconfig for public network access, and the server will be a default domain …
RequestIdstringThe unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.
Success

    "Kubeconfig": …,
