Basically just spawn a new EC2 instance. I choose ubuntu 18.04 server, as Amazon 2 ECS optimized image doesn't have free tier. Log into the instance by

$ ssh ubuntu@<ec2-instance-ip>

No need to install git. But to make git clone works (even for public repo) I need to add my RSA key in this EC2 instance to github. Just follow this link to do so.

Follow this link to install docker.
