[2] [3] docker run -it --rm --privileged --cap-add=ALL --cap-drop=MKNOD ubuntu sh. In the above snapshot, we have added all capabilities except the ‘MKNOD’ which will prevent from creating special files using mknode. We have run the ‘fdisk –l’ command to check that the container is running under privilege mode. To run an Ubuntu container (interactively) in privileged mode, you would use: sudo docker run -it --privileged ubuntu. To test whether the container has access to the host, you can try to create a temporary file system (tmpfs) and mount it to /mnt: mount -t tmpfs none /mnt. Now, list the disk space statistics (in human readable format) with the command: Docker can run commands as the root user if you want, but it also offers a similar flag called Privileged. In the context of containers.

The Docker privileged is an option of the ‘docker run’ command in Docker. It allows our Docker containers to access all devices (that is under the /dev folder) attached to the host as a container is not allowed to access any devices due to security reasons. Not exactly "Dockerfile", but you can do this with an entrypoint script provided you always run the container with --privileged That being said, I would warn against this if at all possible as part of the beauty of docker is that you aren't running things as root. A more better alternative, IMHO, is instead to change this on the host system. The privileged mode. The Docker executor supports a number of options that allows fine-tuning of the build container.

What Does “Root” Even Mean? With Docker one can do --privileged=true but I don't think I can pass this along from my fig.yml via a: sabnzbd : build: ./sabnzbd command: /syzygy/run.sh privileged: true. As that throws a Unsupported config option for sabnzbd service: 'privileged'.
