Dockelixir

⚠️ This is a work in progress.

This project is an experiment to run a multi-application Elixir cluster on top of Docker, Docker-Compose and Docker Swarm. Vagrant virtual machines are used to simulate a production environment. Production containers run on Alpine and are built using multi-stage Dockerfiles and Distillery to be as lightweight as possible.

It also provides a development Docker-Compose environment with watchers.

This project is composed of two separate apps:

1. chat, a Phoenix application using Phoenix Channels.
2. chat_backend, a GenServer holding the state of the chat application in memory.

By keeping the stateful concerns on a separate application part of the same cluster, we can achieve continuous blue-green deployments on stateless applications with little overhead.

Run development cluster with watchers

TODO

Run the production cluster locally

docker-compose up

You can access the web app at http://localhost:4000.

Simulate a production environment with Docker Swarm and Vagrant
