Docker + cuprite

[gencer]

Whenever I try to run chrome inside of a docker container, I get this:

Failure/Error: page.driver.browser.url_whitelist = ["fonts.googleapis.com"]
--
  |  
  | Errno::EACCES:
  | Permission denied - /opt/chrome-linux

It says permission denied. I gave executable permissions to this folder and their files in it. I can start chrome myself. It works. However, cuprite is unable to spawn a process.

Dou you have a working example for docker? How do you start your docker? (I simply start dockerd with tcp socket thats all) What kind of permission do we need to give docker or docker user/group?
