Binding/Unbinding Public API Server Address

Function

This API is used to bind or unbind the public API server address of the cluster by cluster ID.

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

Calling Method

For details, see Calling APIs.

URI

PUT /api/v3/projects/{project_id}/clusters/{cluster_id}/mastereip

Example Requests

Bind the public API server address to a cluster.

{
  "spec" : {
    "action" : "bind",
    "spec" : {
      "id" : "a757a69e-f920-455a-b1ba-d7a22db0fd50"
    }
  }
}

Example Responses

Status code: 200

This indicates that the public API server address of the cluster is successfully bound. No response body is returned if the unbinding is successful.
