User Namespace

User namespaces are a Linux kernel feature that enables a non-root user to simulate superuser privileges, also known as "rootless containers." This feature is particularly useful for running containers without requiring superuser access outside of the container. By utilizing user namespaces, potential damage caused by container break-out attacks can be mitigated. It's important to note that the term "namespace" in the context of user namespaces refers to a Linux kernel feature, and should not be confused with namespaces in the context of Kubernetes.
