Containers aren't virtual machines—they're kernel process isolation using Linux primitives that have existed for decades. In this deep-dive, we pull back the curtain on what Docker really does under the hood.
What You'll Learn:
Why containers are fundamentally different from VMs (and why it matters for security)
The 3 kernel mechanisms that make containers possible: namespaces, cgroups, and filesystem layers
How to see container processes running directly on your host machine
Why Kubernetes dropped Docker support in version 1.24
The OCI specifications that standardize container runtimes and images
Hands-On Demonstrations:
✓ Prove containers share the host kernel by inspecting process trees
✓ See namespace isolation in action with hostname experiments
✓ Inspect Docker's layered filesystem structure
✓ Troubleshoot common container startup failures
