Eric Badger commented on YARN-7516:
-----------------------------------
Also, going back to the registry parsing, what about the case where I build an
image on the node myself and then tag it with a name. Think about a single node
cluster or similar or manually pushing images to every node. If I do that, then
{{docker.privileged-containers.registries}} would prevent you from using the
image as privileged since it didn't come from a registry. It would just be
local to the node. I'm not sure that parsing for a {{/}} delimiter is the best
method here.

> 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.
