Subject [jira] [Commented] (YARN-4262) Allow admins to run privileged docker containers.
Date Wed, 14 Oct 2015 19:08:05 GMT

Sidharta Seethana commented on YARN-4262:
-----------------------------------------

Hi [~aw],

I did consider using a separate list. Running a privileged container in some ways provides
the equivalent of superuser access to the underlying node. So, the question here would be
: should we expose such functionality to anybody who is not in the 'admin' role for the cluster?
Thoughts?

thanks,
-Sidharta

> There are scenarios where privileged containers are necessary in order to run certain
kinds of applications (one example is trying to run postresql/oracle inside containers). However,
given the security implications, we should ensure that : 
> 1) privileged containers are disabled by default, even for admins 
> 2) if enabled, only admins should be allowed to launch such containers and 
> 3) Not all containers launched by admin users need to be privileged containers : admin
users need to explicitly request that a privileged container be launched.
