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

Within the Target VM

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.

How to add environment variables to nginx.conf

This is the hack approach to adding environment variables to the nginx configuration files. As with most Google results for this search, the reason is Docker.

The setup

I intended to deploy two Docker containers.

Single-page Application Project Structure

..with .NET / F# (or Node.js / Express), AngularJS (or Facebook React + RxJS), TypeScript, Gulp.js (or Grunt), NuGet...

Goals

• Project structure should reflect application's logic (as opposed to regular MVC apps which all look the same)
• Group assets by feature rather than by type (including views, scripts, documentation, tests etc.)
• Allow developers to edit client-side and server-side code independently from each other
