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.

Make Sandstorm and other web server coexist in the same port while keeping HTTPS encryption.

Introduction

The purpose of this tutorial is to set up SNI Proxy so it’s possible to use Sandstorm verified SSL encryption while coexisting with another web server that also uses SSL.

The main reason is to allow other users to connect with your Sandstorm instance in the standard HTTPS port (443) and keep using that port also for any other web apps.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.
