Typing vagrant from the command line will display a list of all available commands.

Be sure that you are in the same directory as the Vagrantfile when running these commands!

Creating a VM

  • vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.
  • vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.

Starting a VM

  • vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)

Rails secrets management with Figaro and Capistrano

Use of figaro gem (or something like dotenv) in all environments.

The Figaro config/application.yml file with all the secrets will be git-ignored. So on every deployment server I had to manually add the file shared/config/application.yml and then linked automatically on each deployment to the current version of the app by adding in config/deploy.rb:

set :linked_files, %w{config/application.yml}

For development config/application.yml is something like the following:

#!/usr/bin/env python2
import os
import gym
import sys
import random
import itertools
from time import time
from copy import copy
from math import sqrt, log
