Developer Mountain Environment Variables

An Ansible role for creating and sourcing environment variable scripts in /etc/default. These scripts are will be sourced in .profile, .bashrc & .bash_profile to ensure you envvars are available to apps, users and cronjobs.

There are 2 types of files created:

1. App specific files. These are sourced for one particular apps environment.
2. An optional, single shared script called dvmtn_shared. This is sourced by all app scripts. Use it to keep shared config in one place, such as monitoring tool API tokens.

Installation

$ ansible-galaxy install dvmtn.env

Setup

1. Declare a dictionary called dvmtn_app_env.
2. Create a key under dvmtn_app_env for each app.
3. Create a dictionary under each app. Keys will become the name of an environment variable, with the values becoming the value of the environment variable.
4. (Optional) Declare a dictionary called dvmtn_shared_env. The keys will become environment variables with the value given, inside /etc/default/dvmtn_shared.

Example Playbook

- hosts:
    - my_app
  vars_files:
    - "host_vars/{{ inventory_hostname }}_vault.yml"
  roles:
  - role: dvmtn.env

Example multi-app usage

dvmtn_shared_env:
  RAILS_ENV: "qa"
  SECRET_KEY_BASE: "1234"
  DATABASE_HOST: localhost
  DATABASE_PORT: 5432

dvmtn_app_env:
  app_1:
    DATABASE_DATABASE: "{{ app_1_database }}"
    DATABASE_USERNAME: "{{ app_1_username }}"
    DATABASE_PASSWORD: "{{ app_1_password }}"
  app_2:
    DATABASE_DATABASE: "{{ app_2_database }}"
    DATABASE_USERNAME: "{{ app_2_username }}"
    DATABASE_PASSWORD: "{{ app_2_password }}"

This will create 3 files: /etc/default/dvmtn_shared, /etc/default/app_1 & /etc/default/app_2

Requirements

Tested on ubuntu 14.04 and 16.04 LTS but it should work on other versions that are similar.
