Jib
Jib builds Docker and OCI container images for Java applications without requiring a Docker daemon.
What Jib is
Jib builds Docker and OCI container images for Java applications without requiring a Docker daemon. It is available as Maven and Gradle plugins, a Java library, and a command-line interface, giving Java projects several ways to use it. Jib separates application contents into layers, so code changes can be rebuilt without rebuilding the whole image. It can push images to a container registry of the user's choice, uses an OpenJDK base image by default, and allows a custom base image. The project says that rebuilding an image with the same contents produces the same image. It also supports local build-cache backends and multi-architecture builds, and works with Google Cloud Build. Repository examples cover Spring Boot, Micronaut, multi-module projects, and Spark Java with a Java Agent. Jib is free and open source under Apache License, Version 2.0. The project is not an officially supported Google product; usage questions are directed to Stack Overflow, with GitHub issues and a FAQ also available.

Who it suits
Jib is suited to Java developers building container images, particularly those using Maven, Gradle, or Java libraries. Its daemonless build method may suit projects that do not want a Docker daemon in the image-building process.
Verdict
Jib offers Java-focused image building through plugins, a library, or a CLI, with layered and reproducible builds. Note that Google does not officially support the project.
