Convert a static public IP to an EIP by calling ConvertNatPublicIpToEip - Elastic Compute Service - Alibaba Cloud - Elastic Compute Service

Converts the public IP address (PublicIP) of a VPC-type ECS instance to an Elastic IP Address (EIP).

Operation description

After a public IP address is converted to an EIP, the EIP is billed separately. Make sure that you fully understand the billable methods of EIPs.

When you invoke this operation, the ECS instance must meet the following conditions:

The instance is in the Stopped (Stopped) or Running (Running) state.
No EIP is attached to the instance.
The instance has no pending configuration change nodes.
The public bandwidth cannot be 0 Mbit/s.
For subscription instances, the billing method for public bandwidth must be pay-by-traffic. Public IP addresses with the pay-by-bandwidth billing method cannot be converted to EIPs. Pay-as-you-go instances are not subject to this restriction. For more information, refer to Transform the billing method for network usage.
The VPC-type subscription ECS instance does not expire within 24 hours.

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.
