Rebase an image onto a new base

$ crane rebase [image:tag] --old_base [old:base] --new_base [new:base] -t [rebased:tag]

crane rebase [options] image

crane rebase replaces the base layers of an image with layers from a different base image. This is useful for updating base images without rebuilding.

--old_base image

Original base image.

New base image.

Tag for the rebased image.

Requires that the old base layers exactly match layers in the image. May not work if the image was built with modifications to base layers.
