If you don’t want to use sudo when you use the docker command, create a Unix group called docker and add users to it. The docker daemon always runs as the root user. By default that Unix socket is owned by the user root and other users can only access it using sudo. The docker daemon binds to a Unix socket instead of a TCP port. Important to read: post-installation steps for Linux (it also links to Docker Daemon Attack Surface details). $ dockerd-rootless.sh -experimentalĪs Rootless mode is experimental, users need to always run dockerd-rootless.sh with –experimental. Users need to run dockerd-rootless.sh instead of dockerd. In the recent release of the experimental rootless mode on GitHub, engineers mention rootless mode allows running dockerd as an unprivileged user, using user_namespaces(7), mount_namespaces(7), network_namespaces(7). Warning: The docker group (or the group specified with -G) is root-equivalent see Docker Daemon Attack Surface details and this blogpost on Why we don't let non-root users run Docker in CentOS, Fedora, or RHEL (thanks michael-n).

As of 0.9.0, you can specify that a group other than docker should own the Unix socket with the -G option. The docker daemon must always run as the root user, but if you run the docker client as a user in the docker group then you don't need to add sudo to all the client commands. Starting in version 0.5.3, if you (or your Docker installer) create a Unix group called docker and add users to it, then the docker daemon will make the ownership of the Unix socket read/writable by the docker group when the daemon starts. By default that Unix socket is owned by the user root, and so, by default, you can access it with sudo.

The docker daemon always runs as the root user, and since Docker version 0.5.2, the docker daemon binds to a Unix socket instead of a TCP port. The docker manual has this to say about it:

Rootless mode is currently only provided for nightly builds that may not be as stable as you are used to.Īs of docker 19.3 this is obsolete (and more dangerous than need be):.

Only Ubuntu-based distros support overlay filesystems in rootless mode.

Exposing ports from containers currently requires manual socat helper process.

cgroups resource controls, apparmor security profiles, checkpoint/restore, overlay networks etc.

Some limitation to the rootless mode include: Video about this from Hardening Docker daemon with Rootless modeĪ few Caveats to the rootless Docker modeĭocker engineers say the rootless mode cannot be considered a replacement for the complete suite of Docker engine features. No more messing with elevated permissions, root and anything that might open up your machine when you did not want to. Good news: the new docker (version 19.03 (currently experimental)) will be able to run rootless negating the problems that can occur using a root user.
