InvalidAMIID.NotFound，AWS 错误消息：AMI ID 'ami-c1aaabb5' 不存在

Question

我正在尝试以编程方式启动带有 EBS 的 Ubuntu 12.04 LTS Server 64 位。我写了以下代码：

Placement placement = new Placement("eu-west-1b");
RunInstancesRequest runInstancesRequest = new RunInstancesRequest()
    .withPlacement(placement).withInstanceType("t1.micro")
    .withImageId("ami-c1aaabb5").withMinCount(1).withMaxCount(1)
    .withSecurityGroupIds("testGroup").withKeyName("testKey")
    .withUserData(Base64.encodeBase64String(startupScript.getBytes()));
RunInstancesResult runInstances = amazonEC2.runInstances(runInstancesRequest);
List<Instance> instances = runInstances.getReservation().getInstances();

但是，我收到此错误：

AWS 错误代码：InvalidAMIID.NotFound，AWS 错误消息： AMI ID 'ami-c1aaabb5' 不存在

我在 Amazon AWS 控制台和以下 URL 中找到了该实例 ID：http://cloud-images.ubuntu.com/releases/precise/release-20121001/

我做错了什么？

Answer 1

我发现，默认情况下，请求被发送到美国弗吉尼亚数据中心，设置正确的端点解决了问题。

public AmazonEC2 createAmazonEC2() {
    AmazonEC2 ec2 = new AmazonEC2Client(createAwsCredentials());
    ec2.setEndpoint("https://eu-west-1.ec2.amazonaws.com");
    return ec2;
}

private AWSCredentials createAwsCredentials() {
    AWSCredentials credentials = new BasicAWSCredentials(awsAccessKey, awsSecretKey);
    return credentials;
}
