• How to use Spring Boot with Google Distroless Container Images?

Dockerfiles:

• Dockerfile: Google Distroless based image

docker build -t spring-demo-distroless .

• Dockerfile-debug: Google Distroless based image with a shell for debugging

docker build -t spring-demo-distroless-debug -f Dockerfile-debug .

• Dockerfile-jdk: bellsoft/liberica-openjre-alpine:17 based image that contains only a JRE for a smaller image.

docker build -t spring-demo-jre -f Dockerfile-jdk .

To build the image with buildpacks:

./gradlew bootBuildImage
