How To Automate Elixir-Phoenix Deployment with Distillery and edeliver on Ubuntu 16.04 | DigitalOcean By: Mohideen 31-40 minutes

Introduction Built on the Erlang programming language, Elixir is a functional programming language that's popular for its focus on developer productivity and ease of writing highly concurrent and scalable applications.

Phoenix is a web framework built on Elixir to allow for the creation of highly performant web applications.

And when combined with two additional tools — Distillery and edeliver — you can completely automate the deployment of Phoenix projects from your development environment to a production server.

Distillery compiles Elixir applications into a single package that you can then deploy elsewhere. It also generates packages that allow for hot-swapping of code, which means you can upgrade live applications with no downtime. All of this can be done with little to no configuration on your part, which

sets Distillery apart from many other options. edeliver automates this build and deployment process by taking care of repetitive tasks like building the application, transferring the built package to the server, migrating the database, and starting/updating the server. If needed, you can even configure edeliver to allow for an intermediate staging setup, too.

In this tutorial, you'll install Erlang, Elixir, and Phoenix 1.3 on a local development machine and on a production server, you'll simplify SSH communication between the two locations, and then you'll create a sample Phoenix project to build and deploy with edeliver. Finally, you'll secure the production server with an Nginx reverse proxy and SSL certificate.

By the end of the tutorial, you'll have a single command that can: build a Phoenix release that is compatible with your production environment deploy the release to your production environment start your application in a production environment hot-swap the current production release by deploying a new release without any downtime

Prerequisites Before starting, ensure that you have the following: An Ubuntu-based local development machine. Although this tutorial's instructions are written for an Ubuntu-based local development machine, one strength of this deployment process is that it's completely independent of the production 2 of 34
