Use ReleaseEipAddress to release an elastic IP address - Elastic IP Address - Alibaba Cloud - Elastic IP Address

Releases a specified elastic IP address (EIP).

Operation description

Before you invoke this operation, take note of the following information:

Before you release an EIP, make sure that the following conditions are met:
- Only EIPs in the Available state can be released.
- Only EIPs that use the pay-as-you-go billing method can be released. Subscription EIPs cannot be released.
The ReleaseEipAddress operation is asynchronous. After you send a request, the system returns a request ID. However, the EIP instance is not immediately released because the release node is still running in the background. You can invoke DescribeEipAddresses to query the status of the EIP instance:
- If the EIP instance is in the Releasing state, the EIP instance is being released. In this state, you can only execute query operations and cannot execute other operations.
- If the EIP instance cannot be found, the EIP instance is released.
The ReleaseEipAddress operation does not support concurrent release of the same EIP instance.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
