如何使用AWS SDK for .Net为我拥有的实例创建图像？ （AMI）

Question

我有一个Amazon EC2实例，我需要能够以编程方式从中创建AMI（图像）。我正在尝试以下方法：

CreateImageRequest rq = new CreateImageRequest();

rq.InstanceId = myInstanceID;
rq.Name = instance.KeyName;
rq.Description = "stam";
rq.NoReboot = true;

IAmazonEC2 ec2;
AmazonEC2Config ec2conf = new AmazonEC2Config();
ec2 = AWSClientFactory.CreateAmazonEC2Client(ec2conf);
// CreateImageResponse imageResp;
Amazon.EC2.Model.CreateImageResponse imageResp = null;
try
{
    imageResp = ec2.CreateImage(rq);
}
catch (AmazonServiceException ase)
{
    MessageBox.Show(ase.Message);
}

结果始终是AmazonServiceException，表示存在NameResolutionFailure。

我如何克服这个问题？我尝试了不同的可能＆＃34; name＆＃34;可能性，但找不到合适的。

string amiID = ConfigurationManager.AppSettings[AmazonConstants.AwsImageId];
                string keyPairName = ConfigurationManager.AppSettings[AmazonConstants.AwsKeyPair];
                List<string> groups = new List<string>() { ConfigurationManager.AppSettings[AmazonConstants.AwsSecurityGroupId] };
                var launchRequest = new RunInstancesRequest()
                {
                    ImageId = amiID,
                    InstanceType = ConfigurationManager.AppSettings[AmazonConstants.AwsInstanceType],
                    MinCount = 1,
                    MaxCount = 1,
                    KeyName = keyPairName,
                    SecurityGroupIds = groups,
                    SubnetId = ConfigurationManager.AppSettings[AmazonConstants.AwsSubnetId]
                };
                RunInstancesResponse runInstancesResponse = amazonEc2client.RunInstances(launchRequest);
                RunInstancesResult runInstancesResult = runInstancesResponse.RunInstancesResult;
                Reservation reservation = runInstancesResult.Reservation;

问题最终解决了！

事实证明，一些代码行正在做已经完成的事情并删除了这部分：

IAmazonEC2 ec2;
AmazonEC2Config ec2conf = new AmazonEC2Config();
ec2 = AWSClientFactory.CreateAmazonEC2Client(ec2conf);
// CreateImageResponse imageResp;
Amazon.EC2.Model.CreateImageResponse imageResp = null;

让事情更清晰，没有错误的重复发生！现在它有效！
