Show HN: Docker-repack – Speed up Docker image pulls

Love this idea! ty

I wasn't sure how to load the images back into docker at first. I tried `docker load` but I get this error:

    $ (cd ci-repack && tar cfv - .) | docker load
    ./
    ./oci-layout
    ./index.json
    ./blobs/
    ./blobs/sha256/
    ./blobs/sha256/2ad6ec1b7ff57802445459ed00e36c2d8e556c5b3cad7f32512c9146909b8ef8
    ./blobs/sha256/9f3908db1ae67d2622a0e2052a0364ed1a3927c4cebf7e3cc521ba8fe7ca66f1
    open /var/lib/docker/tmp/docker-import-1084022012/blobs/json: no such file or directory

Then I noticed the `skopeo copy` in one of the github actions workflows. That got me further. The image was able to be pushed to a registry. But I am getting this error when pulling the repacked image:

    failed to register layer: duplicates of file paths not supported

Thanks for trying it out! I’ve tested this on a lot of public images, but it hasn’t been “battle tested” yet.

Are you able to share the image you’re using with me, or a reproduction case? Even the base images would help.
