Flattenator

Flattenator takes a layered Docker image as input, and replaces it with a flattened single-layer image as output, preserving metadata in so far as possible.

Operation

Flattenator must be invoked from a machine with Python 3 (and click) installed, and docker must be in the PATH. Further, docker login must have already been run to allow the running user to push an image.

Flattenator will download the image requested, push that image with the tag exp_{tag}_layered (so as not to destroy the initial image), flatten the image, and then push the flattened image under both the original tag and exp_{tag}_flattened.
