Wangda Tan commented on YARN-7516:
----------------------------------
Thanks [~eyang],
It makes sense, however I think the config name is a bit confusing:
bq. docker.privileged-containers.registries
Sounds like it only takes effect when {{--privileged}} appears. Same as the
documentation:
bq. Comma separated list of trusted docker registries for running trusted
privileged docker containers. By default, no registries are defined.
Is it better to rename it to {{docker.dontainer.trusted-registries}}?

> Hadoop YARN Services can support using private docker registry image or
> docker image from docker hub. In current implementation, Hadoop security is
> enforced through username and group membership, and enforce uid:gid
> consistency in docker container and distributed file system. There is cloud
> use case for having ability to run untrusted docker image on the same cluster
> for testing.
> The basic requirement for untrusted container is to ensure all kernel and
> root privileges are dropped, and there is no interaction with distributed
> file system to avoid contamination. We can probably enforce detection of
> untrusted docker image by checking the following:
> # If docker image is from public docker hub repository, the container is
> automatically flagged as insecure, and disk volume mount are disabled
> automatically, and drop all kernel capabilities.
> # If docker image is from private repository in docker hub, and there is a
> white list to allow the private repository, disk volume mount is allowed,
> kernel capabilities follows the allowed list.
> # If docker image is from private trusted registry with image name like
> "private.registry.local:5000/centos", and white list allows this private
> trusted repository. Disk volume mount is allowed, kernel capabilities
> follows the allowed list.
