What is Ruby on Rails?
Ruby on Rails or, simply, Rails is an open source web application framework which runs on the Ruby programming language. It is a full-stack framework. This means that "out of the box", Rails can create pages and applications that gather information from a web server, talk to or query a database, and render templates. As a result, Rails features a routing system that is independent of the web server.
How to use this image
Create a Dockerfile in your Rails app project
FROM rails:onbuild
Put this file in the root of your app, next to the Gemfile.
This image includes multiple ONBUILD triggers which should cover most
applications. The build will COPY . /usr/src/app, RUN bundle install,
EXPOSE 3000, and set the default command to rails server.
You can then build and run the Docker image:
docker build -t my-rails-app .
docker run --name some-rails-app -d my-rails-app
You can test it by visiting http://container-ip:3000 in a browser or, if you
need access outside the host, on port 8080:
docker run --name some-rails-app -p 8080:3000 -d my-rails-app
You can then go to http://localhost:8080 or http://host-ip:8080 in a
browser.
