Create Amazon EC2 Instance with API

Question

Does com.amazonaws.services.ec2 contain a method to create a brand new EC2 instance from an existing AMI? I'm looking to do this from the Java SDK, not the web management console.

Answer 1

Here is a sample to create EC2 Instances with Amazon AWS SDK for Java :

// 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++; } 

Source code (create RDS, EC2 and ELB instances) is available at http://code.google.com/p/xebia-france/source/browse/training/xebia-spring-travel/trunk/xebia-spring-travel-amazon-aws/src/main/java/fr/xebia/demo/amazon/aws/AmazonAwsInfrastructureMaker.java?spec=svn1781&r=1781
