How to Deploy on Seenode

1. Connect Your Repository: Go to the Seenode dashboard, select New Web Service, and choose this Git repository.
2. Confirm Settings: Seenode will detect the Elixir environment and suggest the correct commands.
   • Build Command:

     mix local.hex --force && mix local.rebar --force
     mix deps.get --only prod
     MIX_ENV=prod mix compile
     MIX_ENV=prod mix assets.build
     MIX_ENV=prod mix assets.deploy
     

   • Start Command: MIX_ENV=prod mix phx.server
3. Deploy: Click Create Web Service.

That's it! Your Phoenix app will be deployed and available at a public URL.

Environment Variables

Required for Production:

• SECRET_KEY_BASE: Generate this with mix phx.gen.secret in your project root. This is used to sign/encrypt cookies and other secrets.

Key Features on Seenode

• Production-Ready: Your Phoenix app runs in a managed Elixir environment with optimized performance and reliability.
• Port Binding: This example is configured to listen on port 80 by default in production. The app will automatically bind to port 80 unless overridden by the PORT environment variable.
• API Endpoint: Includes a working /api endpoint that returns JSON responses for easy testing and integration.
• Seamless Scaling: Scale your service horizontally or vertically with a few clicks from the Seenode dashboard as your traffic grows.
• Live Reload: Development-friendly with automatic code reloading and asset compilation.

Local Development

To start your Phoenix server locally:

• Run mix setup to install and setup dependencies
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server
• Visit localhost:4000 from your browser
• Test the API at localhost:4000/api
