Working with ansible-vault

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.

This is a little trick I use to spin up the packages instalation on Debian/Ubuntu boxes in Vagrant.

I add a simple function that checks if a directory named something similar to ~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/partial (it may have another path in Windows or MacOS) and create the directory if it doesn't already exist.

def local_cache(basebox_name)
  cache_dir = Vagrant::Environment.new.home_path.join('cache', 'apt', basebox_name)
  partial_dir = cache_dir.join('partial')
  partial_dir.mkdir unless partial_dir.exist?
 cache_dir

Vagrant with Ansible Provisioner on Windows

Long story short, ansible does not work on a Windows control machine, so you basically have to:

either run ansible --connection=local ... in the target vm
set up a separate control vm where ansible is installed via shell provisioner

Below are Vagrantfile examples for both approaches

	cd k8s-specs

	git pull

	export AWS_ACCESS_KEY_ID=[...]

	export AWS_SECRET_ACCESS_KEY=[...]

	aws --version

	#!/usr/bin/env bash

	# To run:
	# $ brew uninstall s3cmd && brew install s3cmd --HEAD
	# $ s3cmd --configure # fill in w/ amazon account vars
	# $ cd path/to/local/static/site
	# $ wget https://gist.githubusercontent.com/tomfuertes/9175005/raw/make-website.sh
	# $ bash make-website.sh
	#
	# NOTE: cfcreate takes ~15 minutes to run on AWS.

	# Bootstrap script for use with http://boxstarter.org/
	# To use append the URL to the raw snippet to http://boxstarter.org/package/nr/url?
	# (e.g. http://boxstarter.org/package/nr/url?https://gist.githubusercontent.com/mikemoate/0915288fff447b640cdb/raw/83b32099ea8f21d06604ae70003312b7492b8cd8/boxstarter-script-work)

	# NOTE: You may see errors from some packages if you have already installed the software before using boxstarter.
	# (some MSI's handle this badly and so exit with the wrong code, I've seen this for HipChat, RoyalTS, Virtualbox and Vagrant)

	# Windows settings
	Set-WindowsExplorerOptions -EnableShowHiddenFilesFoldersDrives -EnableShowProtectedOSFiles -EnableShowFileExtensions -EnableShowFullPathInTitleBar
	Set-TaskbarOptions -Size Small -Lock -Dock Bottom
