You can call the CreateCluster operation to create a Container Service for Kubernetes (ACK) cluster. ACK clusters include ACK managed clusters, ACK dedicated clusters, ACK Serverless clusters, ACK Edge clusters, ACK clusters that support sandboxed containers, and registered clusters. For more information about how to create different types of ACK clusters, see the following usage notes.

Operation description

This topic describes all request parameters for creating a Container Service for Kubernetes (ACK) cluster. For more information about how to call the API to create each type of ACK cluster, refer to the following topics:

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
