Jib is an open-source, 100% Java-based tool that builds OCI (Docker v2) compliant container images without a Dockerfile or even a container runtime present. It can be used as a standalone CLI tool but is most commonly used as a Maven or Gradle build step plugin. Jib simplifies developers' lives by automating the process of building and deploying container images, eliminating the need to learn Dockerfile syntax or install unfamiliar tools. It also helps architects manage standardization through the well-known Maven or Gradle project hierarchy facilities. Jib builds OCI compliant images, allowing users to leverage industry-standard tools like Snyk container scanner to inspect, deploy, and run their application. Additionally, Jib provides a repeatable build strategy that aims to create the exact same layer hashes for builds against the same codebase.
