COPY Gemfile ./ RUN gem install bundler && bundle install --jobs 20 --retry 5 # Copy the main application. ./ # Expose port 3000 to the Docker host, so we can access it # from the outside.EXPOSE 3000 # The main command to run when the container starts.
We can now access the default start page at localhost:3000.
It’s not a very useful app, but it’ll do for our purpose.
# Install apt based dependencies required to run Rails as # well as Ruby Gems. So let’s move our development environment over to Postgre SQL instead.
As the Ruby image itself is based on a # Debian image, we use apt-get to install those. We could add the database to our container, but there’s a better way to do this.
CMD ["rails", "server", "-b", "0.0.0.0"]If you’re not happy with the default locale in your Docker container, you can switch to another one quite easily.
Install the required package, regenerate the locales, and configure the environment variables.... While SQLite might be fine for a simple app, you wouldn’t use it in production.Now, let’s move this app to use in a Docker-based environment. It’s a young project and still in beta, but we’ve had great success using it internally.If you already have Docker up and running, you can skip this step and move on to Step 2, Dockerizing right away. See their installation instructions for how to get it running on your computer.We specify a tag via the -t option, so we can reference the container later on.We now have our Rails application running inside a Docker container, but how do we actually access it from our computer?RUN apt-get update && apt-get install -y \ build-essential \ nodejs # Configure the main working directory.This is the base # directory used in any further RUN, COPY, and ENTRYPOINT # commands.RUN mkdir -p /app WORKDIR /app # Copy the Gemfile as well as the and install # the Ruby Gems.This is a separate step so the dependencies # will be cached unless changes to one of those two files # are made.Also # tell the Rails dev server to bind to all interfaces by # default.CMD ["bundle", "exec", "rails", "server", "-b", "0.0.0.0"]After adding the above file as Dockerfile to your repository, we can now build the container and start running commands with it.
