使用API​​创建Amazon EC2实例

Question

com.amazonaws.services.ec2是否包含从现有AMI创建全新EC2实例的方法？我希望从Java SDK而不是Web管理控制台执行此操作。

Answer 1

以下是使用Amazon AWS SDK for Java创建EC2实例的示例：

// CONNECT TO EC2

InputStream credentialsAsStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("AwsCredentials.properties");
Preconditions.checkNotNull(credentialsAsStream, "File 'AwsCredentials.properties' NOT found in the classpath");
AWSCredentials credentials = new PropertiesCredentials(credentialsAsStream);

AmazonEC2 ec2 = new AmazonEC2Client(credentials);
ec2.setEndpoint("ec2.eu-west-1.amazonaws.com");

// CREATE EC2 INSTANCES
RunInstancesRequest runInstancesRequest = new RunInstancesRequest()
    .withInstanceType("t1.micro")
    .withImageId("ami-62201116")
    .withMinCount(2)
    .withMaxCount(2)
    .withSecurityGroupIds("tomcat")
    .withKeyName("xebia-france")
    .withUserData(Base64.encodeBase64String(myUserData.getBytes()))
;

RunInstancesResult runInstances = ec2.runInstances(runInstancesRequest);

// TAG EC2 INSTANCES
List<Instance> instances = runInstances.getReservation().getInstances();
int idx = 1;
for (Instance instance : instances) {
  CreateTagsRequest createTagsRequest = new CreateTagsRequest();
  createTagsRequest.withResources(instance.getInstanceId()) //
      .withTags(new Tag("Name", "travel-ecommerce-" + idx));
  ec2.createTags(createTagsRequest);

  idx++;
}

提供源代码（创建RDS，EC2和ELB实例）

希望这有帮助，

RunInstances是方法，它应该在SDK中。

 var launchRequest = new RunInstancesRequest()
                {
                    ImageId = amiID,
                    InstanceType = ConfigurationManager.AppSettings["AwsInstanceType"],
                    MinCount = 1,
                    MaxCount = 1,
                    KeyName = keyPairName,
                    SecurityGroupIds = groups,
                    SubnetId = ConfigurationManager.AppSettings["AwsSubnetId"],

                };
                RunInstancesResponse runInstancesResponse = amazonEc2client.RunInstances(launchRequest);
                var InstanceId = runInstancesResponse.Reservation.Instances[0].InstanceId;
                var trequest = new CreateTagsRequest();
                trequest.Resources=new List<string>(){InstanceId};
                List<Tag> tags=new List<Tag>();
                Tag tag=new Tag("Name","TestCodeFinal");
                tags.Add(tag);
                trequest.Tags = tags;
                amazonEc2client.CreateTags(trequest);
                Reservation reservation = runInstancesResponse.Reservation;
