Spring Boot Deployment Standards
Priority: P0
Implementation Guidelines
GraalVM Native Images (AOT)
- •Use Case: Serverless/CLI tools requiring instant startup.
- •Constraints: Register reflection via Runtime Hints. Libraries must be compatible.
- •Build: Use
bootBuildImage(Gradle) orspring-boot:build-image(Maven).
Containerization (Docker)
- •Layered JAR: Use standard Layered JAR support to optimize caching.
- •Security: Run as non-root user (
nobodyorappuser). - •Memory: Set JVM limits proportional to container (
-XX:+UseContainerSupport).
Graceful Shutdown
- •Enable:
server.shutdown=graceful(default 30s timeout). - •Process: Stops accepting new requests, processes active ones.
Anti-Patterns
- •Fat JAR:
**No Fat JARs in Docker**: Use layers. - •Root User:
**No Root**: Use restricted user. - •Baked Config:
**No Baked Secrets**: Use Env/ConfigMaps.
