Amazon EC2:
- Overview: Amazon EC2 provides resizable compute capacity in the cloud, allowing for scalable and secure application deployment.
- Key Features:
- Variety of instance types to suit different workloads.
- Integration with other AWS services for enhanced functionality.
- High availability and reliability.
Docker:
- Overview: Docker is a platform for developing, shipping, and running applications in containers, ensuring consistent environments across development and production.
- Key Features:
- Lightweight and efficient resource usage.
- Portability across different environments.
- Rapid deployment and scalability.
Combining EC2 with Docker:
- Benefits:
- Simplified deployment process with containerized applications.
- Improved resource utilization and isolation.
- Enhanced scalability to handle varying loads.
- Implementation Steps:
- Launch an EC2 Instance:
- Go to the AWS Management Console.
- Navigate to the EC2 Dashboard.
- Click on “Launch Instance.”
- Select an Amazon Machine Image (AMI) (e.g., Amazon Linux 2).
- Choose an instance type (e.g., t2.micro for free tier).
- Configure instance details, add storage, and tag the instance.
- Configure the security group to allow SSH (port 22) and other necessary ports (e.g., HTTP/HTTPS).
- Review and launch the instance, and create/download a key pair for SSH access.
- Install Docker on the EC2 Instance:
- SSH into your EC2 instance using the key pair.
- Update the package index:
sudo yum update -y - Install Docker:
sudo amazon-linux-extras install docker - Start the Docker service:
sudo service docker start - Add the ec2-user to the docker group:
sudo usermod -aG docker ec2-user - Log out and log back in to apply the group changes.
- Deploy a Docker Container:
- Pull a Docker image (e.g., Nginx):
docker pull nginx - Run the Docker container:
docker run -d -p 80:80 nginx - Access the running container by navigating to the EC2 instance’s public IP address in your web browser.
- Pull a Docker image (e.g., Nginx):
- Launch an EC2 Instance:
