Phoenix

Add a service from your Phoenix repo. Nixpacks detects elixir from mix.exs. A Dockerfile in the service root always wins.

Set PHX_HOST and PORT. Release builds via Dockerfile are typical for production.

Deploy from GitHub

1. Dashboard → New project (or open an existing canvas).
2. + Service → Git repository. Pick the repo and branch.
3. Review staged changes and Deploy.
4. Generate a *.stackblaze.app domain, or attach a custom domain.

Override install / build / start on the service if detection is wrong. Typical start: mix phx.server.

Docker

If you already have a Dockerfile, StackBlaze uses it. The process must listen on PORT.

Data

+ Service → Databases for Postgres, Redis/Valkey, MySQL, and others. Wire DATABASE_URL from the service Variables tab or fromDatabase in stackblaze.yaml.

CLI
