Snippet Java for EC2

With snippet Java for EC2, you can free your mind

1. Create Instance by code from AMI exist

   AmazonEC2 ec2 = new AmazonEC2Client(new ClasspathPropertiesFileCredentialsProvider());
   ec2.setRegion(Region.getRegion(Regions.AP_NORTHEAST_1));
   RunInstancesRequest runInstancesRequest = new RunInstancesRequest();
   runInstancesRequest.setInstanceType("m1.small");
   runInstancesRequest.setImageId("ami-115aaf15");
   runInstancesRequest.setMinCount(Integer.valueOf(1));
   runInstancesRequest.setMaxCount(Integer.valueOf(1));
   runInstancesRequest.setKeyName("keypair");
   ArrayList securityGroup = new ArrayList();
   securityGroup.add("sgrsslave");
   runInstancesRequest.setSecurityGroups(securityGroup);
   ec2.runInstances(runInstancesRequest);
   

2. Get instance-id

   String ec2Id = "";
   String inputLine;
   URL url = new URL("http://169.254.169.254/latest/meta-data/instance-id");
   URLConnection con = url.openConnection();
   try (BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()))) {
     while ((inputLine = in.readLine()) != null) { ec2Id = inputLine; }
   }
   System.out.println(ec2Id);
