Eric Yang commented on YARN-8927:
---------------------------------
[~ebadger] I think it's still admin mistake because the repository name can be
preconfigured to a host in local domain which would have no chance to contact
docker hub even if a repository is later setup to try to impersonate. YARN's
trusted registry acl can avoid untrusted docker hub repository. The discussion
is digressing. I agree that adding the local image white list can tighten
security further for images without '/' characters or used. This jira can't
solve docker run pulling remote image when image is absent or remote image name
is identical to local image name. [~csingh] is solving the docker image
localization issues in YARN-9228. It may help to solve precheck of image
existence in her story instead.
> Support trust top-level image like "centos" when "library" is configured in
> "docker.trusted.registries"

> There are some missing cases that we need to catch when handling
> "docker.trusted.registries".
> The container-executor.cfg configuration is as follows:
> {code:java}
> docker.trusted.registries=tangzhankun,ubuntu,centos{code}
> It works if run DistrubutedShell with "tangzhankun/tensorflow"
> {code:java}
> "yarn ... -shell_env YARN_CONTAINER_RUNTIME_TYPE=docker -shell_env
> YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=tangzhankun/tensorflow
> {code}
> But run a DistrubutedShell job with "centos", "centos[:tagName]", "ubuntu"
> and "ubuntu[:tagName]" fails:
> The error message is like:
> {code:java}
> "image: centos is not trusted"
> {code}
> We need better handling the above cases.
