How to Install Docker on AWS?

In the dynamic world of cloud computing, Docker has emerged as a powerful tool for containerization, allowing developers to package and deploy applications seamlessly across different environments. Amazon Web Services (AWS) provides a robust platform for hosting applications, and integrating Docker with AWS can enhance flexibility and scalability. In this guide, we will explore step-by-step instructions on how to install Docker on AWS, enabling you to harness the full potential of containerization in the cloud.


Before diving into the installation process, make sure you have an AWS account with the necessary permissions to create and manage resources. Additionally, ensure that you have an EC2 instance running with the appropriate security group and key pair configured.

Step 1: Connect to Your EC2 Instance

Use SSH to connect to your EC2 instance. Replace your-key.pem and ec2-instance-ip with your key pair and instance's public IP address.

ssh -i your-key.pem ec2-user@ec2-instance-ip

Step 2: Update Package Repository

Ensure your package repository is up to date before installing Docker.

sudo yum update -y

Step 3: Install Docker

Install Docker using the package manager yum.

sudo yum install docker -y

Step 4: Start Docker Service

Start the Docker service and enable it to start on boot.

sudo service docker start
sudo chkconfig docker on

Step 5: Add User to Docker Group

Add the current user to the Docker group to run Docker commands without using sudo.

sudo usermod -aG docker $USER

Step 6: Log Out and Log In

To apply the group changes, log out and log back in to your EC2 instance.

ssh -i your-key.pem ec2-user@ec2-instance-ip

Step 7: Verify Docker Installation

Check if Docker is installed correctly by running the following command.

docker --version

Step 8: Run a Docker Container

Test Docker by running a simple container. For instance, run an Nginx web server.

docker run -d -p 80:80 nginx

Step 9: Access Nginx in a Web Browser

Open your web browser and navigate to your EC2 instance's public IP address. You should see the default Nginx welcome page.

Congratulations! You have successfully installed Docker on AWS and run a container. This integration opens up a world of possibilities for deploying and managing applications efficiently in the cloud. Experiment with different containers and explore the full potential of Docker on AWS.
