Question

我尝试将实例启动到子网中，默认设置为不分配公共IP。

使用aws CLI，可以通过添加--associate-public-ip-address：

来完成

aws ec2 run-instances --image-id ami-xxx --count 1 --instance-type m4.large --key-name "xxx" --subnet-id subnet-xxx --security-group-ids sg-xxx --associate-public-ip-address

使用Java SDK启动实例时如何做同样的事情？

RunInstancesRequest runInstancesRequest = new RunInstancesRequest();

runInstancesRequest.withImageId(kAmiId)
                   .withInstanceType(kInstanceType)
                   .withMinCount(1)
                   .withMaxCount(1)
                   .withKeyName(kKeyName)
                   .withSecurityGroupIds(kSecurityGroups)
                   .withMonitoring(false)
                   .withSubnetId(kSubnet);

让它像这样工作：

InstanceNetworkInterfaceSpecification networkSpec = new InstanceNetworkInterfaceSpecification();
networkSpec.setDeviceIndex(0);
networkSpec.setSubnetId(kSubnet);
networkSpec.setGroups(Arrays.asList(kSecurityGroups));
networkSpec.setAssociatePublicIpAddress(true);

runInstancesRequest.withImageId(kAmiId)
                   .withInstanceType(kInstanceType)
                   .withMinCount(1)
                   .withMaxCount(1)
                   .withKeyName(kKeyName)
                   .withMonitoring(false)
                   .withNetworkInterfaces(networkSpec)
                   .withAdditionalInfo("--associate-public-ip-address");

RunInstancesResult result = mClient.runInstances(runInstancesRequest);

看起来你必须通过提供InstanceNetworkInterfaceSpecification来设置它。像这样：

List<InstanceNetworkInterfaceSpecification> interfaces = new ArrayList<InstanceNetworkInterfaceSpecification>();
interfaces.add(new InstanceNetworkInterfaceSpecification().withAssociatePublicIpAddress(true));

runInstancesRequest.withNetworkInterfaces(interfaces);
