Spring Boot

Add a service from your Spring Boot repo. Nixpacks detects java from pom.xml or build.gradle. A Dockerfile in the service root always wins.

Nixpacks detects Maven/Gradle. server.port must be $PORT. Heap is the service memory limit.

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: java -jar app.jar.

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
