debootstrap inside a docker container

docker chroot

Here's my problem: I want to build a chroot environment inside a docker container. The problem is that debootstrap cannot run, because it cannot mount proc in the chroot:

W: Failure trying to run: chroot /var/chroot mount -t proc proc /proc

(in the log the problem turns out to be: mount: permission denied)

If I run --privileged the container, it (of course) works... I'd really really really like to debootstrap the chroot in the Dockerfile (much much cleaner). Is there a way I can get it to work?

Thanks a lot!

You could use the fakechroot variant of debootstrap, like this:

fakechroot fakeroot debootstrap --variant=fakechroot ...

Cheers!
