Subject [jira] [Commented] (YARN-3854) Add localization support for docker images
Date Mon, 25 Jul 2016 08:13:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-3854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15391515#comment-15391515

Zhankun Tang commented on YARN-3854:
------------------------------------

[~sidharta-s], Thanks for the update! 
For the security issue exposed by "docker load", my conclusion after investigation is that
it seems no way to solve this. We cannot ensure the tarball "docker load" imported is trusted
even if we managed to solve the tag name conflicts.

And docker pull during localization seems duplicated with YARN-3289.

> We need the ability to localize docker images when those images aren't already available
locally. There are various approaches that could be used here with different trade-offs/issues
: image archives on HDFS + docker load ,  docker pull during the localization phase or (automatic)
docker pull during the run/launch phase. 
> We also need the ability to clean-up old/stale, unused images.
