The first step, however, is to install Docker Compose. If you're running Windows or Mac, Docker Compose is already installed as it comes in the Docker Toolbox. Linux users can easily get their hands on Docker Compose by following the instructions on the docs. Since Compose is written in Python, you can also simply do pip install docker-compose.

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using. Once you used above command it will update packages on ec2 instance or it will give message “no packages marked for update” it means your ec2 instance already have all the latest packages installed. Now, you can install Docker using below command, #yum install docker -y.
This tutorial explains, how to install docker on EC2 Instance. Before starting, let’s have some brief knowledge about Docker.
Docker is a platform that combines applications and its dependencies in the form of packages, called container. We can run multiple containers on a single Operating System. Containers are not Virtual Machines. Virtual Machines requires Operating System to run applications, but containers do not. As containers don’t need an Operating System, it takes very little time to start and hence it is very faster than Virtual Machines.
The Amazon Linux AMI-based Docker platform can be used to deploy a Docker image (described in a Dockerfile or Dockerrun.aws.json definition) and source code to EC2 instances that are running in an Elastic Beanstalk environment. This Docker platform runs only one container for each instance.

Let’s Install Docker on EC2 Instance
In this tutorial, we will use Amazon Linux to install docker. Amazon Linux/Amazon Linux2 is the Linux Operating System used in EC2 Instance.
Step 1– Log to Linux EC2 Instance and update it.
$ sudo yum update -y
Step 2– Install docker using Yum command
$ sudo yum install docker -y
Step 3– Start Docker Service
$ Service docker start
Step 4– Check docker Version.
$ docker -v
Basic Configuration (Creating Docker File / Running Docker Image)
After you install docker on ec2 , let’s have some basic setup for Docker.
Step 1 – Create a docker file
Dockerfile is a text file where we write instructions to build an image.
Create a folder name Images on the Amazon Linux box.
$ mkdir images
Move to folder images
$ cd images
Create a file name Dockerfile inside images folder
$ nano Dockerfile
Put the content in the following way inside the Dockerfile.
FROM Ubuntu ( It will use the Official image Ubuntu to build your image)
MAINTAINER chandan <[email protected]>
( It sets the Author field of the generated image)
RUN apt-get update ( It will update the image at the time of Build)
CMD [ “echo”, ” Hello World ……….! “] ( It will run echo command when we run the docker container image)

Step 2– Run the docker build command to build the image.
$ docker build .
Note : ( . command is used when you are inside images folder where Dockerfile is present, alternatively you can put the docker file absolute path like /home/ec2-user/images/Dockerfile)
You can run the following command as well to Name and tag your Image. Here myimage is the Name and 01 is Tag of the image.
$ docker build -t myimage:01 .
Step 3– See the Docker Images after build
$ docker images

Step 4 – Run the docker image
$ docker run 07deaa33585e
Here 07deaa33585e is the IMAGE ID that can be seen in docker images command.
You can see here, it executed the echo command as soon as we run the docker image. In the same way, we can run any script, commands or any application by running a docker image.
