Exploring kubernetes privileged pods

Read Original

This technical article investigates the Linux namespace isolation of privileged Kubernetes pods. It clarifies that setting `privileged: true` grants broad Linux capabilities but does not automatically share host namespaces like network, PID, or IPC. The author details findings from testing, showing that only the user namespace is shared by default, and explains how specific pod specs (hostNetwork, hostPID, hostIPC) control actual namespace sharing.
