Vagrant tutorial

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

  • install packages for vim, git
  • create user accounts, as specified in included JSON config files
  • install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

It's a résumé, as a readable and compilable C source file. Since Hacker News got here, this has been updated to be most of my actual résumé. This isn't a serious document, just a concept to annoy people who talk about recruiting and the formats they accept résumés in. It's also relatively representative of my coding style.

Since this is on Hacker News and reddit...

  • No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is a good bit crazier.
  • I apologize for the use of _t in my types. I spend a lot of time at a level where I can do that; "reserved for system libraries? I am the system libraries".
  • Since people kept complaining, I've fixed the assignments of string literals to non-const char *s.
  • My use of type * name, however, is entirely intentional.
  • If you're using an older compiler, you might have trouble with the anonymous unions and the designated initializers - I think gcc 4.4 requires some extra braces to get them working together. Anything reasonably recent should work fine. Clang and gcc (newer than 4.4, at le

Chef 11 has come out, and possibly broken a bunch of your carefully crafted cookbooks. How are you going to test them, though? Here's one way, using chef-solo via Vagrant.

Requirements

  • RVM (or rbenv, but this will use RVM)
  • You're using RVM or rbenv to manage your rubies, right? If not, you should be.
  • Virtualbox
  • some cookbooks you wrote and want to test

Set it up

We don't want to mess up our carefully crafted Chef 10.x environment, right? We'll use rvm gemsets to make a disposable set of gems. If something goes wrong, just close the terminal you're in, or run rvm gemset use default. You'll drop back to the default gemset.
