User Namespace
Glossary Page
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.

Interoperability in manufacturing is often misunderstood. Not because companies doubt its importance, but because it's difficult to visualize what success looks like. This blog uses simple analogies to explain the core challenges: outdated machines that can’t “speak” to modern systems, and people hesitant to share data without context or trust. With solutions like Asset Administration Shells and Data Spaces, manufacturers can unlock hidden value, foster secure collaboration, and take real steps toward digital transformation.
