Using Docker Toolbox on Cygwin

Notes:

  • Docker For Windows is newer and officially recommended over Docker Toolbox, but it doesn't run on Windows Home edition (only Pro) because it requires Hyper-V. The following instructions may or may not apply to Docker For Windows (I haven't tested it).
  • This works on Azure type Dv3 and Ev3 VMs (Windows 2016), as well as regular Windows 10 desktop. I used this Terraform script to provision a VM for testing.

Loading variables from .env files in Ansible

Ansible has various ways of looking up data from outside sources, including plain text password files, CSV files and INI files. But it doesn't seem to have a lookup for .env files, as used in Laravel projects, also available for PHP, Ruby, Node.js, Python and others.

One option is to launch Ansible with the Ruby dotenv command line script... But that requires Ruby, which seems like overkill to me.

So here is a simpler solution that I use. It consists of:

  1. The .env file itself
  2. A small shell script that loads the .env file into environment variables - ansible-playbook.sh

Laravel's Dependency Injection Container in Depth

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

Getting started with SWI-Prolog

Today (May 2017) I decided to learn a bit about Prolog. Here is how to start using it...

Install it on Ubuntu:
