​
Install Docker

​
Step 1: Install Docker Desktop

💡 What is Docker Desktop? Docker Desktop is a user-friendly tool for managing Docker containers. It simplifies the process of building, testing, and deploying applications.
  • Download Docker Desktop from the official website.
  • Install Docker Desktop on your machine.
  • Verify Installation by running docker --version in the terminal.
📝 Ensure Docker is correctly installed and configured to avoid issues later.

​
Step 2: Run a Pre-Built Container Image

  • Run Nginx Container: 
    docker run -d -p 80:80 nginx
  • Access the Nginx Welcome Page at http://localhost.
💡 What is Nginx? Nginx is a high-performance web server used to serve web content. It’s commonly used in containerized environments.

​
Build Your Custom Image

​
Step 1: Create a Dockerfile

Create a Dockerfile with the following content: 
FROM nginx:latest
COPY index.html /usr/share/nginx/html/
EXPOSE 80
💡 Understanding Dockerfile Instructions
  • FROM nginx:latest uses the latest Nginx image as a base.
  • COPY index.html /usr/share/nginx/html/ replaces the default Nginx HTML file.
  • EXPOSE 80 makes port 80 available for connections.

​
Step 2: Create Your HTML Content

Create index.html: 
<!doctype html>
<html>
  <head>
    <title>My Web App</title>
  </head>
  <body>
    <h1>Hello from YOURNAME's custom Docker image!</h1>
  </body>
</html>
💡 Customize Your Webpage Replace YOURNAME with your name to personalize the message.

​
Step 3: Build Your Docker Image

Build the Docker Image: 
docker build -t my-web-app .
📝 Ensure all files are in the correct directory and the Dockerfile is properly configured.

​
Step 4: Run Your Custom Image

Run the Custom Image: 
docker run -d -p 80:80 my-web-app
Verify Deployment by accessing http://localhost in your browser.
⚠️ Port Conflicts Ensure no other services are using port 80 to avoid conflicts.

​
Deploy to Elastic Beanstalk

​
Step 1: Set Up Elastic Beanstalk

Create an Elastic Beanstalk Application:
  • Navigate to the Elastic Beanstalk console.
  • Choose Create Application and follow the prompts.
  • Select Docker as the platform.
💡 What is Elastic Beanstalk? Elastic Beanstalk simplifies the deployment of applications by managing the underlying infrastructure.

​
Step 2: Upload Your Application Code

Prepare Your Application:
  • Create a ZIP file containing your Dockerfile and index.html.
  • Upload the ZIP File in Elastic Beanstalk.
📝 Ensure files are at the root level of the ZIP to avoid deployment issues.

​
Step 3: Configure and Deploy

Configure Environment Settings:
  • Set the environment type to Single Instance.
  • Ensure the correct platform version and branch are selected.
  • Deploy your application and access it via the provided domain link.
⚠️ Resource Costs Remember to terminate environments and delete resources when they are no longer needed to avoid unnecessary costs.

​
Delete Resources

​
Step 1: Terminate Elastic Beanstalk Environment

  • Navigate to your environment in the Elastic Beanstalk console.
  • Select Terminate Environment and confirm the action.
💡 Cleanup is Crucial Properly deleting resources ensures you don’t incur unexpected charges.

​
Step 2: Remove Docker Containers

List all containers: 
docker ps -a
Stop and remove containers: 
docker stop <container_id>
docker rm <container_id>
📝 Replace <container_id> with the actual ID of your container.

​
Step 3: Delete S3 Buckets

  • Navigate to the S3 Console.
  • Delete buckets associated with your Elastic Beanstalk application.
⚠️ Bucket Deletion Ensure you have the necessary permissions and confirm deletions to prevent data loss.

​
Conclusion

Congrats! You’ve successfully deployed a containerized application to AWS Elastic Beanstalk. Remember to clean up resources to manage costs and maintain security best practices. Happy coding! 🎉
