Docker container breakout?
Hi all, I'm a maintainer of Docker. As others already indicated this doesn't work on 1.0. But it could have.Please remember that at this time, we don't claim Docker out-of-the-box is suitable for containing untrusted programs with root privileges. So if you're thinking "pfew, good thing we upgraded to 1.0 or we were toast", you need to change your underlying configuration now. Add apparmor or selinux containment, map trust groups to separate machines, or ideally don't grant root access to the application.Docker will soon support user namespaces, which is a great additional security layer but also not a silver bullet!When we feel comfortable saying that Docker out-of-the-box can safely contain untrusted uid0 programs, we will say so clearly.
