Fly.io

This skill provides comprehensive guidance for deploying applications to Fly.io, including initial setup, database management, CI/CD integration, and production operations.

When to Use

This skill activates automatically when working with:

• Fly.io-specific tasks ("fly.io", "deploy to fly", "fly.io setup", "flyctl")
• Fly.io configuration ("fly.toml", "fly app", "fly launch")
• Fly.io database operations ("fly postgres", "fly pg")
• Fly.io environment management ("fly secrets", "fly env")
• Fly.io monitoring ("fly logs", "fly status", "fly dashboard")
• Fly.io GitHub Actions ("fly deploy github action", "flyctl in CI/CD")

Core Principles

1. Security First: Always encrypt sensitive data, never commit unencrypted secrets
2. Database Safety: Use proxying for database access, maintain regular backups
