In the world of web development, the optimization of deployment processes plays a crucial role in enhancing efficiency.
Rails 7.1 introduces an exciting enhancement by providing default Docker-related files for new applications to make the setup process easier and simplifies the deployment process of our application in production environments using Docker.
bin/docker-entrypoint are now bundled within the Rails application. These files cater specifically to production deployments rather than local development.
- Build the Docker image:
- Create a Docker volume:
- Run the Rails app:
- Start a console or runner from this Docker image:
To create a multi-platform image (e.g., for deployment on Apple Silicon, AMD, or Intel) and push it to Docker Hub, follow these steps:
- Login to Docker Hub:
- Create a buildx builder and set it as the current builder:
- Build and push the image:
For local development, we can use docked. Setting up Rails for the first time with all the dependencies necessary can be daunting for beginners.
Docked Rails CLI uses a Docker image to make it much easier, requiring only Docker to be installed.
