Ecto Release Migrations Setup

Overview

In Elixir releases, Mix is not available. This skill creates a Release module that handles database creation, migration, and rollback via bin/app_name eval commands.

Workflow

1. Detect app name and repos

   • Check mix.exs for app name
   • Check config/config.exs or config/runtime.exs for Ecto repos

2. Create Release module

   • Location: lib/<app_name>/release.ex
   • Must handle multiple repos if present

3. Verify config

   • Ensure config/runtime.exs has production database config
   • Check for DATABASE_URL or explicit config
