Deploy an Elixir / Phoenix application on onesubnet

onesubnet runs your Elixir/Phoenix applications (fault tolerance, real-time). Deploy via Git.

1. Prepare the project

• A mix.exs at the root.
• Phoenix reads the port via PORT (endpoint configured in config/runtime.exs):

config :my_app, MyAppWeb.Endpoint,
  http: [ip: {0, 0, 0, 0}, port: String.to_integer(System.get_env("PORT") || "4000")]

2. Deploy

1. Connect your Git repository in the panel.
2. Build command: mix deps.get && mix assets.deploy
3. Start command: mix phx.server (or mix release then _build/prod/rel/my_app/bin/my_app start).

3. Environment variables

DATABASE_URL, SECRET_KEY_BASE… in Settings → Environment.

4. Logs

Live console in the panel. Phoenix uses Elixir’s Logger module.
