What is rootless Docker and what security advantage does it provide over traditional Docker?

Accepted Answer

Rootless Docker provides a security advantage by running the Docker daemon and containers as a non-root user using user namespaces. This prevents a compromise or escape from granting root access to the host, reducing privilege escalation risk compared to traditional Docker.
