Deploying Elixir Mix project on Dokku

Setup VPS

Create clean Ubuntu 14.04 image on Digital Ocean or any other VPS.

Login to VPS via ssh:

$ ssh root@server_ip

Install Dokku:

$ wget https://raw.githubusercontent.com/dokku/dokku/v0.4.5/bootstrap.sh
$ sudo DOKKU_TAG=v0.4.5 bash bootstrap.sh

Create a Dokku app:

$ dokku apps:create app_name

Make it support multiple buildpacks:

$ dokku config:set app_name BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git

Ensure your locale is set to UTF-8:

$ dokku config:set app_name LC_ALL=en_US.utf8

Set prod env:

$ dokku config:set app_name MIX_ENV=prod

Put any ENV keys to app config:

$ dokku config:set app_name SECRET_KEY=secret

Add changes to your git repository on local computer

Create .buildpacks file:

$ echo "https://github.com/HashNuke/heroku-buildpack-elixir.git" >> .buildpacks

Ensure you have prod.secret.exs in git. Replace all ENV keys with System.get_env("SECRET_KEY")

Commit changes and add git remote:

$ git remote add dokku dokku@server_ip:app_name

Deploy your app to Dokku:

$ git push dokku master
