Billie Rinaldi commented on YARN-7516:
--------------------------------------
I tried to run an untrusted image with patch 011 and got "Invalid docker
capability requested." Since capabilities are configured globally rather than
per container, shouldn't it just run the container without the capabilities in
that case?
We have two mechanisms that control mounts, the mount whitelist and local
resource mounts. This patch excludes untrusted images from using both. I wonder
if we should allow untrusted images to use local resources, files localized by
YARN for use by their application. I feel like the httpd example app should
work without having to change its image name to the trusted image namespace. It
doesn't need any special capabilities or privileges, but it does need local
resources for customizing its configuration. What do you think?

> 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.
