Connect to ec2 instance through JAVA - spring

Question

I have created REST API to create EC2 instance using AWS JAVA SDK provided.
Now I am trying to connect to created EC2 instance and then need to install software's in the instance again through java. I didn't find any appropriate article for this. Is there any possible way to do this? I don't want to use SSH client like putty.. Thanks..

Answer 1

Sounds like you're looking for a java ssh client.
You should set up key authentication and use the ssh client library from java to execute the installation for you.

Answer 2

public static void connectToEC2(){
try{
JSch jsch=new JSch();
String user = "User-name";
String host = "host";
int port = 22;
File directory = new File(".");
String privateKey = directory.getCanonicalPath() + File.separator + "pem file path";
jsch.addIdentity(privateKey);
System.out.println("identity added ");
Session session = jsch.getSession(user, host, port);
System.out.println("session created.");
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
Channel channel=session.openChannel("shell");
channel.setInputStream(System.in);
channel.setOutputStream(System.out);
channel.connect(3*1000);
}
catch(Exception e){
System.out.println(e);
}
}
