Primary LanguageJava

spring-boot-layered-jar

Proof-of-concept of building and packing a Spring Boot application as a layered jar. Demonstrates building Docker images using either Cloud Native Buildpacks or a Dockerfile.

The code shows in detail:

  • how to build a layered, executable jar
  • how to build a OCI image using Cloud Native Buildpacks
  • how to biuld a OCI image using Dockerfile
  • how to pass build information (e.g. the commit sha) to the app

Build with Cloud Native Buildpacks

Run ORG_GRADLE_PROJECT_appBuild=foo gradle bootBuildImage to build the image using Clould Native Buildpacks. The resulting image name will be: ad-buildsrv-01:5000/ab-layered:foo.

Build with Docker

Run docker build -t ad-buildsrv-01:5000/sb-layered:baz . to build the image using the supplied Dockerfile. The resulting image name will be: ad-buildsrv-01:5000/ab-layered:baz.
