Elastic Compute Service:DescribeInstanceAttachmentAttributes

Last Updated:Sep 29, 2024

Queries the information about the private pools that Elastic Compute Service (ECS) instances match, such as the private pool types and IDs.

Operation description

A private pool is generated after an elasticity assurance or a capacity reservation is created. The private pool is associated with information about the instances that are created by using the private pool. You can configure a private pool when you create an instance. This way, the instance matches the elasticity assurance or capacity reservation that is associated with the private pool.

When a private pool expires, data about the association between instances and the private pool becomes invalid. If you call this operation to query the information about the private pool, empty values are returned.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

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:

  • 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.
