Subject [jira] [Commented] (YARN-5428) Allow for specifying the docker client configuration directory
Date Wed, 03 Aug 2016 12:25:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15405835#comment-15405835
] 

Shane Kumpf commented on YARN-5428:
-----------------------------------

Just to add that in the YARN model, we run the docker commands as root and hence the file
needs to be owned by root with 400 permissions minimum. YARN is also not aware of the actual
username and password, only where the client config is stored. The administrator or user would
need to run "docker login" interactively at least once to generate the config.json file and
distribute it across the cluster if they wanted to leverage the client config for credentials.

> 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
file.
> This change will be needed to allow YARN to automatically pull images at localization
time or within container executor.
