Craig Condit commented on YARN-10494:
-------------------------------------
[~ebadger], yes the tool currently connects to a (Docker-compatible) registry.
We might be able to add local support (though this would require all the
various tar.gz layers / metadata files to exist). I'd be inclined to add that
in a follow-up ticket if there's support.
The builds are reproducible – I finally found the issue with our internal
builds that led to deltas (turned out to be the modification timestamp of the
root directory). I've since corrected that and it now gets set to the latest
timestamp encountered during processing.

> *YARN-9564* defines a docker-to-squashfs image conversion tool that relies on
> python2, multiple libraries, squashfs-tools and root access in order to
> convert Docker images to squashfs images for use with the runc container
> runtime in YARN.
> *YARN-9943* was created to investigate alternatives, as the response to
> merging YARN-9564 has not been very positive. This proposal outlines the
> design for a CLI conversion tool in 100% pure Java that will work out of the
> box.
