Jib vs Skaffold: What are the differences?
Jib: Containerize your Java application (by Google). Jib builds Docker and OCI images for your Java applications and is available as plugins for Maven and Gradle; Skaffold: Easy and Repeatable Kubernetes Development. Skaffold is a command line tool that facilitates continuous development for Kubernetes applications. You can iterate on your application source code locally then deploy to local or remote Kubernetes clusters. Skaffold handles the workflow for building, pushing and deploying your application. It can also be used in an automated context such as a CI/CD pipeline to leverage the same workflow and tooling when moving applications to production.
Jib and Skaffold belong to "Container Tools" category of the tech stack.
Some of the features offered by Jib are:
- 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 container image with the same contents always generates the same image. Never trigger an unnecessary update again.
- Daemonless - Reduce your CLI dependencies. Build your Docker image from within Maven or Gradle and push to any registry of your choice. No more writing Dockerfiles and calling docker build/push.
On the other hand, Skaffold provides the following key features:
- No server-side component. No overhead to your cluster.
- Detect changes in your source code and automatically build/push/deploy.
- Image tag management. Stop worrying about updating the image tags in Kubernetes manifests to push out changes during development.
Jib and Skaffold are both open source tools. It seems that Skaffold with 7.16K GitHub stars and 589 forks on GitHub has more adoption than Jib with 7.1K GitHub stars and 606 GitHub forks.
