In the previous blog posts, we discussed deploying a Dockerized Rails application on DigitalOcean and hosting multiple Docker containers on a single Droplet. In this blog post, we'll guide you through deploying a similar application on Amazon AWS, one of the leading cloud providers. This tutorial assumes you've already Dockerized your Rails application.
Step 1: Setting Up an AWS Account and Installing AWS CLI
- Sign up for an Amazon AWS account if you haven't already: https://aws.amazon.com/
- Install the AWS CLI on your local machine by following the official documentation: https://aws.amazon.com/cli/
- Configure the AWS CLI with your access key, secret access key, and default region:
$ aws configure
Step 2: Creating an Amazon Elastic Beanstalk Environment
- Log in to your AWS Management Console and navigate to the Elastic Beanstalk service.
- Click on "Create a new environment."
- Select the "Web server environment" and click "Select."
- Choose "Docker" as the platform, and select "Upload your code" as the application code option.
- Compress your Rails application into a ZIP file, including your Dockerfile and docker-compose.yml. Upload this ZIP file as the source code.
- Configure any additional settings as needed, such as environment variables.
- Create the environment. AWS will provision resources and deploy your application. Once completed, you'll receive a URL for accessing your application.
Step 3: Configuring a Custom Domain and SSL (Optional)
- Navigate to the "Route 53" service in the AWS Management Console.
- Create a hosted zone for your domain.
- Add an "A" record with an alias that points to your Elastic Beanstalk environment.
- Follow the official AWS documentation for requesting and configuring an SSL certificate: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/configuring-https.html
Conclusion
In this blog post, we've demonstrated how to deploy a Dockerized Rails application on Amazon AWS using Elastic Beanstalk. With the provided steps, you can quickly and easily deploy your application to AWS, leveraging their extensive services and scalability options.
