Eric Badger commented on YARN-5534:
-----------------------------------

bq. IMO, I think that feature might be better suited as a separate patch 
though, since it will essentially bypass the whitelist.
I'm ok with it being a separate patch. It's fundamentally different since it 
doesn't depend on user input, while the whitelist volumes would. So I think 
that makes sense. And I'd be happy to work on that patch if that's what we 
decide to do.

> Introduction 
> Mounting files or directories from the host is one way of passing 
> configuration and other information into a docker container. 
> We could allow the user to set a list of mounts in the environment of 
> ContainerLaunchContext (e.g. /dir1:/targetdir1,/dir2:/targetdir2). 
> These would be mounted read-only to the specified target locations. This has 
> been resolved in YARN-4595
> 2.Problem Definition
> Bug mounting arbitrary volumes into a Docker container can be a security risk.
> 3.Possible solutions
> one approach to provide safe mounts is to allow the cluster administrator to 
> configure a set of parent directories as white list mounting directories.
>  Add a property named yarn.nodemanager.volume-mounts.white-list, when 
> container executor do mount checking, only the allowed directories or 
> sub-directories can be mounted.
