What is Jib?

Jib builds optimized Docker and OCI images for your Java applications without a Docker daemon - and without deep mastery of Docker best-practices. It is available as plugins for Maven and Gradle and as a Java library.

Jib works well with Google Cloud Build. For details, see how to use Jib on Google Cloud Build.

How Jib Works

Whereas traditionally a Java application is built as a single image layer with the application JAR, Jib's build strategy separates the Java application into multiple layers for more granular incremental builds. When you change your code, only your changes are rebuilt, not your entire application. These layers, by default, are layered on top of an OpenJDK base image, but you can also configure a custom base image. For more information, check out the official blog post or watch this talk (slides).

See also rules_docker for a similar existing container image build tool for the Bazel build system.
