## What is Jib?

Jib builds optimized Docker and [OCI](https://github.com/opencontainers/image-spec) images for your Java applications without a Docker daemon - and without deep mastery of Docker best-practices. It is available as plugins for [Maven](jib-maven-plugin) and [Gradle](jib-gradle-plugin) and as a Java library.

- [Maven](https://maven.apache.org/): See documentation for [jib-maven-plugin](jib-maven-plugin).
- [Gradle](https://gradle.org/): See documentation for [jib-gradle-plugin](jib-gradle-plugin).
- [Jib Core](jib-core): A general-purpose container-building library for Java.
- [Jib CLI](jib-cli): A command-line interface for building images that uses Jib Core.

Jib works well with Google Cloud Build. For details, see [how to use Jib on Google Cloud Build](docs/google-cloud-build.md).

## Goals

* **Fast** - Deploy your changes fast. Jib separates your application into multiple layers, splitting dependencies from classes. Now you don’t have to wait for Docker to rebuild your entire Java application - just deploy the layers that changed.

* **Reproducible** - Rebuilding your containe
