The Ansible playbook installs everything needed to serve static files from a nginx server over HTTPS.
The server pass A rating on [SSL Labs](https://www.ssllabs.com/).

To use:
 1. Install [Ansible](https://www.ansible.com/)
 2. Setup an Ubuntu 16.04 server accessible over ssh
 3. Create `/etc/ansible/hosts` according to template below and change example.com to your domain
 4. Copy the rest of the files to an empty directory (`playbook.yml` in the root of that folder and the rest in the `templates` subfolder)

Deploying Elixir and Phoenix applications using Docker and Exrm

Goal

By the end of this quick guide, you will know how to compile a Phoenix app release using Exrm and run it inside a Docker container. I've found only a couple of articles that discuss getting an Elixir app up and running inside a Docker container, and even those only touched on some parts of the process. The idea is that this guide will give you a full end-to-end example of how to get all the pieces and parts working together so that you are able to deploy your Phoenix application inside a Docker container.

Assumptions

1. You already have a working Elixir environment with the Phoenix Framework installed
2. You have at least basic working knowledge of Docker, and have installed the Docker tools onto your local environment

Deploying Phoenix on Dokku

Worked 2015-09-08 for Phoenix 1.0.1 on Dokku 0.3.25.

These instructions assume you've set up Dokku. If not, go find a tutorial for that part. My notes for setting it up on Digital Ocean.

On your local machine, in the app's repo

Create a Dokku app:

#!/usr/bin/env elixir

defmodule Committer do
  defstruct [:name, :email]

  def list(repo) do
    repo
    |> from_repo
    |> Stream.unfold(fn str ->
      case String.split(str, "\n", parts: 2, trim: true) do

YandexKassaIntegration::Application.routes.draw do
  # ...
  scope '/yandex_kassa' do
    controller 'yandex_kassa', constraints: { subdomain: 'ssl' } do
      post :check
      post :aviso
      get :success
      get :fail

Problem: Can't use sudo command-limiting in Ansible

The ability to limit sudo users to only be able to execute certain commands doesn't work with Ansible (without a workaround).

This isn't a problem if you're running Ansible as a super-user like root, but if you are allowing others to run Ansible on your systems in order to do things like application deploys, then you need a way to limit their access to the system for basic security.

For example, a line in /etc/sudoers like this:

mokevnin

FROM ruby:2.2.1

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

ENV RAILS_ENV production
ENV REFILE_CACHE_DIR /var/tmp/uploads

RUN curl -sL https://deb.nodesource.com/setup | bash -
