Examples of com.amazonaws.services.ec2.AmazonEC2Client.associateAddress()

com.amazonaws.services.ec2.AmazonEC2Client.associateAddress()

The AssociateAddress operation associates an elastic IP address with an instance.

If the IP address is currently assigned to another instance, the IP address is assigned to the new instance. This is an idempotent operation. If you enter it more than once, Amazon EC2 does not return an error.

@param associateAddressRequest Container for the necessary parametersto execute the AssociateAddress service method on AmazonEC2. @return The response from the AssociateAddress service method, asreturned by AmazonEC2. @throws AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available. @throws AmazonServiceException If an error response is returned by AmazonEC2 indicating either a problem with the data in the request, or a server side issue.

                    associateAddressRequest.setAllocationId(selectedEIP.getAllocationId());
                } else {
                    associateAddressRequest.setPublicIp(publicIp);
                }


                ec2Service.associateAddress(associateAddressRequest);
                logger.info("\n\n\nAssociated " + myInstanceId + " running in zone: " + myZone + " to elastic IP: "
                            + publicIp);
            }
            logger.info("My instance {} seems to be already associated with the EIP {}", myInstanceId, publicIp);
        } else {

            request.setPublicIp(vip.getData().getIp());
            request.setPrivateIpAddress(privateIpAddress);
            request.setNetworkInterfaceId(networkInterface.getNetworkInterfaceId());
            request.setInstanceId(ec2InstanceId);


            AssociateAddressResult response = ec2.associateAddress(request);
            log.info("Associated public IP with assocation id: {}", response.getAssociationId());
        }


        return privateIpAddress;
    }
