Here is how to install docker and docker-compose on the (AWS) Amazon Linux 2 OS running on either an EC2 or Lightsail instance.

Let’s begin by opening a console or SSH session to your EC2 or Lightsail instance. You can do this from within your AWS portal or an SSH tool like Putty. The actual “how to connect” to your server is outside the scope of this article.

Once you are connected, let us start by installing any pending updates on your host.

sudo yum update

Next, we will install Docker.

sudo yum install docker

Create a new membership group for docker and add the ec2-user to it so you can run all of the docker commands without needing to use the sudo command.

sudo usermod -a -G docker ec2-user
id ec2-user
newgrp docker

Now it’s time to add docker-compose.

wget https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m) 
sudo mv docker-compose-$(uname -s)-$(uname -m) /usr/local/bin/docker-compose
sudo chmod -v +x /usr/local/bin/docker-compose

Enable the docker service.

sudo systemctl enable docker.service

Start the docker service.

sudo systemctl start docker.service

Verify that the service is running.

sudo systemctl status docker.service

You can check the docker version with this command.

docker version

And lastly you can check the docker-compose version with this command..

docker-compose version

You have now installed docker and docker-compose on Amazon Linux 2.
I am going to leave off with some helpful controls manage docker on your machine.

sudo systemctl start docker.service #start docker
sudo systemctl stop docker.service #stop docker
sudo systemctl restart docker.service #restart docker
sudo systemctl status docker.service #get the status of docker
