#292 Virtual Machines with Vagrant - RailsCasts

Vagrant is presented as a way to run a Rails application and all of its dependencies in a portable, shareable environment. The page frames it as useful for development, for setting up a staging server, and for trying out a production setup.

Reading notes

#

• Vagrant runs a Rails app and its dependencies in a portable environment.
• The same setup can be used for development, staging, or experimenting with production.
• The page lists Vagrant, VirtualBox, Vagrant Boxes, Chef, rbenv, and ruby-build as resources.
• The example shows forwarding port 3000 in Vagrantfile.
• The example Gemfile adds therubyracer.
• The setup sequence includes installing Vagrant, adding a box, creating a Rails app, initializing Vagrant, starting the virtual machine, and connecting by SSH.
• Inside the virtual machine, it updates packages and installs build tools, zlib, curl, git, SQLite, rbenv, Ruby 1.9.2, bundler, and then runs the Rails server.
• The page also lists common Vagrant commands such as reload, status, suspend, resume, halt, up, package, and destroy.
