[Container-tools] portable docker files with respect to volumes?

[Max Rydahl Andersen]

Hey,

Been battling how to actually write portable docker files that will work 
in native docker, boot2docker, openshift etc.

Things works pretty fine until I hit volumes.

What is the best practice for allowing mount of a volume and that the 
user used in docker have access ?

with boot2docker my user must be root or not having (g)id 1000 otherwise 
it won't be able to write to the volumes [1]

openshift says my user cannot be root and I cannot rely on the numerical 
value of (g)id [2]

Thus how does one make a docker file that will work in both scenarios ?

Anyone with some tips on that ?
