Linux Namespaces Isolation Lab
Interactive evaluation of PID, NET, MNT, UTS, IPC, and USER isolation boundaries.
Linux Kernel Isolation Engine
Linux Namespaces Inspector: The 6 Pillars of Container Isolation
Host OS Perspective (Global)Linux Kernel
Host sees PID 48291 (node server.js) alongside 300 other host processes.
Container Perspective (Isolated)Private Illusion
Container sees PID 1 (node server.js) as the root init process. Host processes are 100% invisible!
Kernel Architectural Role:
Provides private process hierarchy. Signals (SIGKILL, SIGTERM) cannot be sent to host processes from inside the container.
