## What it is
Jib builds optimized Docker and OCI container images for Java applications without requiring a Docker daemon, available as Maven and Gradle plugins, a Java library (Jib Core), and a CLI. It layers applications intelligently for fast incremental rebuilds and produces reproducible images.

## Use cases
- build docker images for java apps without installing docker
- containerize a maven project with a plugin
- containerize a gradle project with a plugin
- speed up container rebuilds by only pushing changed layers
- build reproducible oci images in ci/cd pipelines
- push java app images directly to a registry from the build

## When to choose
- you build Java applications with Maven or Gradle and want container images without Dockerfile maintenance
- your CI environment has no Docker daemon
- you want fast, layered, reproducible image builds

## When to avoid
- you build non-JVM applications
- you need full Dockerfile-level control over image build steps
- you need multi-stage builds with arbitrary build tooling

## Facets
- artifact type: plugin
- maturity: stable
- function: container-runtime, build-tool, deployment, developer-tools
- domain: microservices, cloud-computing
- platform: jvm, cloud, cross-platform
- tags: docker, oci-images, maven-plugin, gradle-plugin, java, container-build, no-docker-daemon, reproducible-builds, containers, devops, kubernetes
