In this episode of The Linux Podcast with Fexingo, Lucas and Luna unpack how Linux namespaces — not Docker or Kubernetes — are the actual kernel feature that makes containers possible. They walk through the seven namespace types (mount, PID, network, user, UTS, IPC, cgroup), explain what happens when you run 'unshare' in a terminal, and discuss why user namespaces are the most security-critical piece of container isolation. Along the way, they mention a real-world case: a developer accidentally escaping a container namespace and the consequences. If you've ever wondered what happens inside a container at the kernel level, this episode gives you the concrete answer.
