ConvertNatPublicIpToEip changes the public IP (NatPublicIp) of a Virtual Private Cloud (VPC) connected instance to an Elastic IP (EIP).

Description

When using this operation, consider the following:

  • The network type of the specified instance must be VPC.
  • The status of the specified instance must be Stopped (Stopped) or Running (Running).
  • The outbound bandwidth of an ECS instance must be greater than 0 Mbps, in case the ECS instance does not have a public IP NatPublicIp.
  • This action fails if you have already bound an EIP to the specified instance.
  • This action fails if ongoing configuration changes exist for the specified ECS instance.
  • This action fails if the specified instance expires in the next 24 hours.
  • Once the public IP NatPublicIp is changed to an EIP, you are billed for using the EIP service. For more information, see EIP document Billing.
