Jib builds optimized Docker and OCI container images for Java applications without needing a Docker daemon or deep Docker expertise.Is it a plugin, a library, or a CLI tool?All three: it's available as a Maven plugin, a Gradle plugin, a general-purpose Java library (Jib Core), and a command-line interface (Jib CLI).
All three: it's available as a Maven plugin, a Gradle plugin, a general-purpose Java library (Jib Core), and a command-line interface (Jib CLI).How do I add it to my build?Add the jib-maven-plugin to your Maven pom.xml or the jib-gradle-plugin to your Gradle build file and follow their quickstart guides; Jib Core can also be used as a library and Jib CLI as a standalone command-line tool.

No, Jib builds and pushes images directly without Docker, so there's no need to write a Dockerfile or have Docker running.What base image does it use by default?By default Jib layers your app on top of an OpenJDK base image, though a custom base image can be configured instead.
By default Jib layers your app on top of an OpenJDK base image, though a custom base image can be configured instead.Why is Jib faster than a typical Docker build?Jib splits your application into multiple layers, separating dependencies from classes, so only changed layers need to be rebuilt and redeployed instead of the whole JAR.
