    Build Server


Go to Digital Ocean
Create new ubuntu droplet

Setup Server


ssh root@<droplet ip>
Create deploy user

sudo adduser deploy
add deploy to sudo group: sudo adduser deploy sudo
add passwordless sudo: visudo ->  s/%sudo  ALL=(ALL:ALL) ALL/%sudo   ALL=NOPASSWD: ALL
copy SSH public keys: find .ssh -print | cpio -pdmv --owner=deploy ~deploy
su deploy


sudo apt-get -y install git
wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb && sudo dpkg -i erlang-solutions_1.0_all.deb
sudo apt-get update
sudo apt-get install -y elixir
sudo apt-get install -y esl-erlang
mix local.hex
mix archive.install https://github.com/phoenixframework/archives/raw/master/phoenix_new.ez
curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo mkdir /opt && sudo chmod -R 777 /opt
sudo mkdir /git && sudo chmod -R 777 /git

Setup EDeliver Project


add edeliver dependency (pointing to master branch on GH for now...): {:edeliver, git: "https://github.com/boldpoker/edeliver.git"}
comment import_config "prod.secret.exs"
add :edeliver to applications list
mix deps.get
mix deps.compile
create .deliver/config file
populate config file with the following:

#!/usr/bin/env bash

APP="my_awesome_app" # name of your release

BUILD_HOST="server ip / hostname" # host where to build the release
BUILD_USER="deploy" # local user at build host
BUILD_AT="/git/my_awesome_app/builds" # build directory on build host
RELEASE_DIR="/git/my_awesome_app/builds/rel/my_awesome_app"

STAGING_HOSTS="server ip / hostname" # staging / test hosts separated by space
STAGING_USER="git" # local user at staging hosts
TEST_AT="/test/my_awesome_app" # deploy directory on staging hosts. default is DELIVER_TO

PRODUCTION_HOSTS="server ip / hostname" # deploy / production hosts separated by space
PRODUCTION_USER="deploy" # local user at deploy hosts
DELIVER_TO="/opt/my_awesome_app" # deploy directory on production hosts

Establish Production Config

We will be using env vars in your config/prod.exs
Make sure to add server: true as we are building a release. Also add check_origin: false if you want to allow websockets from any origin.
config :my_awesome_app, MyAwesomeApp.Endpoint,
  http: [port: {:system, "PORT"}],
  url: [host: System.get_env("HOSTNAME"),
  server: true,
  check_origin: false
...
# import_config "prod.secret.exs"
config :my_awesome_app, MyAwesomeApp.Endpoint,
  secret_key_base: System.get_env("SECRET_KEY_BASE")

Set up environment vars in build host

Add env variables to ~/.profile
export PORT=4000
export HOSTNAME="your-website.com or ip"
export SECRET_KEY_BASE="<generate one using `mix phoenix.gen.secret`>"
```

Bind privileged ports
===========

Forward port 80 to 4000. [Source](http://zotonic.com/docs/0.x/developer-guide/deployment/privilegedports.html)
TODO: Would be cool to instead use `authbind` with edeliver to avoid opening the non-privileged port as well

```
sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to 4000
```

Build On Server
============

- `mix edeliver build release --verbose` in case of error, try: `mix edeliver build release --verbose --skip-mix-clean`
- `mix edeliver deploy release to production --verbose`
- `mix edeliver start production --verbose`

double check that everything is running at your-ip:4000
In order to troubleshoot ssh into the prod host and look at the /opt/app/app/log files
