Subject [jira] [Commented] (YARN-5428) Allow for specifying the docker client configuration directory
Date Tue, 06 Feb 2018 20:35:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-5428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16354507#comment-16354507

Jian He commented on YARN-5428:

The added check is a client side check. But I realize this is a generic issue for all requests
object, a single size check alone won't cover all scenarios, I take back my suggestions, I
think we can go with second last patch.

> The docker client allows for specifying a configuration directory that contains the docker
client's configuration. It is common to store "docker login" credentials in this config, to
avoid the need to docker login on each cluster member. 
> By default the docker client config is $HOME/.docker/config.json on Linux. However, this
does not work with the current container executor user switching and it may also be desirable
to centralize this configuration beyond the single user's home directory.
> Note that the command line arg is for the configuration directory NOT the configuration
> This change will be needed to allow YARN to automatically pull images at localization
time or within container executor.
