This is different to userns-remap mode, where the daemon still operates with root privileges.\n\nEvaluate the specific requirements and security posture of your environment to determine if rootless mode is the best choice for you. For environments where security is a paramount concern and the limitations of rootless mode do not interfere with operational requirements, it is a strongly recommended configuration. Alternatively consider using Podman as an alternative to Docker.\n\n> Rootless mode allows running the Docker daemon and containers as a non-root user to mitigate potential vulnerabilities in the daemon and the container runtime. > Rootless mode does not require root privileges even during the installation of the Docker daemon, as long as the prerequisites are met.\n\nRead more about rootless mode and its limitations, installation and usage instructions on Docker documentation page.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
