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:

My notes for Dokku on Digital Ocean.

These may be a bit outdated: Since I originally wrote them, I've reinstalled on a newer Dokku and may not have updated every section below.

Commands

Install dokku-cli (gem install dokku-cli) for a more Heroku-like CLI experience (dokku config:set FOO=bar).

# List/run commands when not on Dokku server (assuming a "henroku" ~/.ssh/config alias)

ssh henroku dokku

Emoji Spec

Tired of the same, dull rspec output? liven it up with some emoji!

Below are the sets presently available, and their corresponding id. if you don't set an ID, one will be randomly chosen every run. Emoji icons may not render in certain terminals.

Migrating from intercom.io to analytics.js

Intercom.io use 2 level hash and separate user identification and user tracking. Analytics.js use plain hash to handle both identification and tracking. Below you can see migration scheme:

var intercomSettings = {                         analytics.initialize({
                                                    
  app_id: 'bk7tlzy4',                              'Intercom': 'bk7tlzy4'
