Eric Yang commented on YARN-7516:
---------------------------------
Other possible solution is to use docker user remapping feature to enforce user
namespace consistency with Hadoop cluster. However, the current implementation
of docker user remapping is a map of json of users to append to docker daemon.
It does not look like a scalable solution for arbitrary username that might
exist in docker hub.
> Security check for untrusted docker image

> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Eric Yang
>
> 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.
