Eric Badger commented on YARN-9562:
-----------------------------------
Hey [~eyang], thanks for trying out the patch! Here are what I believe are the
bare minimum configs necessary to get things up and running. For now, the C
code in YARN-9561 uses docker configs from container-executor.cfg, so the only
thing that you will need to add to that is {{feature.oci.enabled=1}} and then
of course make sure that the mount lists are in line with the mounts you set in
yarn-site.xml
Additionally, I have uploaded the docker-to-squash tool to YARN-9564 which
should help you create the squashFS images on HDFS. It will also set up the
image-tag-to-hash file. See YARN-9564 for more details on that.

> This JIRA will be used to add the Java changes for the new
> RuncContainerRuntime. This will work off of YARN-9560 to use much of the
> existing DockerLinuxContainerRuntime code once it is moved up into an
> abstract class that can be extended.
