From Zero to Elixir Deployment
summary
Shows how to build a self-contained Elixir release (example: a tiny clock app) using Distillery releases, package it into a Docker image with a multi-stage Dockerfile, and run it with docker-compose on a VPS. Demonstrates runtime config via Distillery configuration providers, creates custom commands for DB migrations, and explains that hot upgrades work with releases but not when deploying immutable Docker containers. Claims atomic deployments reduce provider lock‑in; a previous PaaS move caused ~36 hours downtime.
