Eric Yang commented on YARN-8927:
---------------------------------
[~tangzhankun] Sorry for the confusion. The "docker run" pull strategy is
still being discussed in https://github.com/moby/moby/issues/13331 and
https://github.com/moby/moby/issues/34394 . My statement would be inaccurate
for "docker run" out side of YARN. Docker run without explicit pull will not
update the image to latest. In YARN, there is on going effort to move docker
pull into localization phase. If YARN-3854 is done, then it might have pull
once and update to latest side effect. The checking logic can be done in
localization phase after YARN-3854. I am concerned that YARN's separate effort
might be a snow flake effect, if Docker decided to bring 13331 to closure.

> Key: YARN-8927
> URL: https://issues.apache.org/jira/browse/YARN-8927
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Zhankun Tang
> Assignee: Zhankun Tang
> Priority: Major
>
> 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.
