It's a simple bootstrap to get a new Rails development environment up and running. To get more information about running Rails environment with docker-compose take a look at official Compose and Rails tutorial.
First you have to install docker and docker-compose. Here're some good guides to doing it depending on the OS you're running:
To create a new application from the bootstrap assuming that your project's name is your-project
run:
git clone --depth 1 git://github.com/zinovyev/rails-dev.git your-project
cd your-project
make
Now you can visit your fresh rails installation on localhost:3000
.
To stop application use:
cd your-project
make stop
To start application use:
cd your-project
make start
