> CLI tool for docker-to-squashfs conversion (pure Java)
> ------------------------------------------------------
>
> Key: YARN-10494
> URL: https://issues.apache.org/jira/browse/YARN-10494
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: yarn
> Affects Versions: 3.3.0
> Reporter: Craig Condit
> Assignee: Craig Condit
> Priority: Major
> Attachments: YARN-10494.001.patch,
> docker-to-squashfs-conversion-tool-design.pdf
>
>
> *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.
