Can jib be used without a repository?

Question

The normal docker build command creates the image locally and does not do an automatic push to a registry. Is it possible to do the same with jib using the Gradle plugin?

Answer 1

gradle jibDockerBuild builds and pushes to a local Docker Engine (daemon).

However, jibDockerBuild followed by docker push is very inefficient compared to building and pushing directly to a registry with gradle jib due to the limited capability of the Docker Engine API. Likewise, if you are making small incremental changes during development and you have a large base image or dependencies, it's even possible that gradle jib followed by docker pull is much faster than gradle jibDockerBuild. This is because gradle jib can upload only those layers that changed (regardless of the order of layers).

FYI, gradle jibBuildTar is another Jib task that creates a local image tarball (of either OCI or Docker format).
