Streamline Your Ruby on Rails Development with Docker

Are you looking for a quick and efficient way to set up a complete Ruby on Rails development environment? With Docker, you can have a fully functional Rails stack—including PostgreSQL and all necessary configurations—up and running in just a few commands!

For those interested in exploring how to Dockerize a Ruby on Rails application, I’ve shared the code in this GitHub repository:

Why Use Docker for Rails Development?

Setting up a Rails environment can sometimes be cumbersome, with dependency issues and system conflicts slowing you down. Docker simplifies this process by creating a containerized environment where everything is pre-configured and isolated. That means:

• No more dependency conflicts.
• Easy onboarding for new developers.
• Consistent development and production environments.

Get Started in Just a Few Commands

With this setup, you can have Rails, PostgreSQL, and all necessary connections running effortlessly:

git clone [email protected]:ggerman/ruby_on_rails_dockerized.git
cd repository-name
./bin/start.sh up
        

This script will:

• Build the necessary Docker containers.
• Set up PostgreSQL and MailCatcher.
• Install dependencies (bundle install, yarn install).
• Set up the database (db:create, db:migrate).

Once this is complete, you’re ready to start coding!

Features of This Setup

• Pre-configured PostgreSQL Database: No need to install and configure manually.
• MailCatcher for Email Testing: Easily capture and preview emails sent from your app.
• Seamless Development Experience: Access the Rails console, database, and test suite within the container.

Running Tests

To ensure everything is working correctly, run your test suite with a single command:

./bin/test.sh
        

For individual tests:

./bin/test.sh spec/model/post_spec.rb:22
        

Keeping Your Environment Updated

If you make changes to your Docker setup, simply rebuild the environment:

./bin/start.sh build
        

Contribute and Improve

This project welcomes contributions! If you’d like to improve or extend this environment:

1. Fork the repository.
2. Create a new branch: git checkout -b feature/your-feature
3. Commit your changes: git commit -am 'Add some feature'
4. Push to the branch: git push origin feature/your-feature
5. Open a pull request.
