This is an update to the original blog post about creating docker images with Spring Boot 2.3.
There were a few things related to image creation that changed between the first milestone of Spring Boot 2.3 and the GA release.

The two new features introduced in Spring Boot 2.3 to help improve image creation techniques were: layered jars and buildpack support.

Layered Jars

The layered jar feature evolved quite a bit as we started adding support for custom layers. While the need to express layers that the jar should be split into for image creation was evident, changing the format of the jar to do so no longer seemed necessary.
Spring Boot 2.3 includes support for layering a jar using a layers.idx file. The layers index file provides a list of layers and the parts of the jar that should be contained within them. Layers are written in the order that they should be added to the Docker/OCI image.

On behalf of the team and everyone that contributed, I am pleased to announce that the first milestone of Spring Boot 2.3 has been released and is available from our milestone repository. This release closes 167 issues and pull requests.

Highlights of this first milestone include:

• Support for building Docker images using Cloud Native Buildpacks
• Support for building layered jars for building optimized Docker images
• End-to-end traceability for Configuration Properties
• Numerous dependency upgrades
• Support for Spring Data Neumann M1 which ships with major driver upgrades
