A Virtual Machine for Ruby on Rails Core Development
This project automates the setup of a development environment for Ruby on Rails core development. This is the easiest way to build a box with everything ready to start hacking on your pull request, all in an isolated virtual machine.
The virtual machine runs on top of VirtualBox.
We use Vagrant to build and provision the virtual machine:
gem install vagrant
How To Build The Virtual Machine
Building the virtual machine is this easy:
git clone https://github.com/rails/rails-dev-box.git cd rails-dev-box vagrant up
If the base box is not present that command fetches it first. The setup itself takes about 3 minutes in my MacBook Air. After the installation has finished, you can access the virtual machine with
Port 3000 in the host computer is forwarded to port 3000 in the virtual machine. Thus, applications running in the virtual machine can be accessed via localhost:3000 in the host computer.
What's In The Box
SQLite3, MySQL, and Postgres
System dependencies for nokogiri, sqlite3, mysql, mysql2, and pg
Databases and users needed to run the Active Record test suite
The first time you log into the box you generally want to configure Git:
git config --global user.name "John Doe" git config --global user.email email@example.com
set up your SSH keys, and clone your fork.
Virtual Machine Management
When done just log out with
^D and suspend the virtual machine
then, resume to hack again
to shutdown the virtual machine, and
to boot it again.
And to completely wipe the virtual machine from the disk destroying all its contents:
vagrant destroy # DANGER: all is gone
Please check the Vagrant documentation for more information on Vagrant.
