Basically this is just something I hacked together one night to learn about Kubernetes and see how well Elixir worked with it. Thanks to bitwalker's libcluster, it works quite well.
If you want to use this project, you'll need to make some changes, and perform some steps in your kubernetes environment. If you haven't used kubernetes before I highly recommend giving it a spin via Google Container Engine, it's a great experience. If you use GCE, their Cloud Shell product makes it really painless to do all of this without messing around with your local machine, but you'll need to install Elixir there (use Erlang Solution's debian repo).
MIX_ENV=prod mix release --env=prod
kubectl create -f examplephx-aio.yaml
I probably forgot something, don't be afraid to reach out @bbhoss :)
