Install Docker and Git

Installing Docker

To allow the EC2 instance to package the source code and for the EC2 instance in the development environment to deploy that package as a server, we need to install Docker on both EC2 instances.

First, we need to SSH into the EC2 instance in the development environment and install Docker using the following command:

sudo yum install -y docker

After the installation, we will start the Docker service on Linux:

sudo service docker start

Add the current Linux user to the Docker group so that the user can interact with Docker, and check if the current user can use Docker:

# Create group if it doesn't exist
sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker
docker ps

Next, SSH into the EC2 instance in the production environment and install Docker following the same steps as above.

Installing Git

To clone the project we just forked onto the EC2 instance in the development environment, we need to install Git on that EC2 instance.

sudo yum install -y git-all

Go to the project repository on GitHub and copy the URL to clone the source code.

git clone https://github.com/{your-user-name}/imga

And that’s it! We now have:

• Docker and Git installed on the EC2 instance in the development environment (for source code management, packaging the source code, and pushing Docker images to ECR).
• Docker installed on the EC2 instance in the production environment (for pulling Docker images from ECR and deploying the server).
