Who is this presentation for?

  • Anyone working with containers or responsible for global container strategy

Prerequisite knowledge

  • A working knowledge of Linux, Docker, and Kubernetes

Materials or downloads needed in advance

  • A WiFi-enabled laptop

What you'll learn

  • Understand how Linux container internals work


Scott McCarty leads a detailed examination of container architecture from the Linux kernel to Kubernetes, covering security and resource controls, kernel structures, and low-level storage and network functions. You’ll follow a logical path from container host and image to container runtime to orchestrator, as Scott answers questions like: How do sVirt/SELinux, SECCOMP, namespaces, and isolation really work? How does the Docker daemon work? How does Kubernetes talk to the Docker daemon? How are container images made? You’ll leave ready to apply your current technical and architectural knowledge to containers.

Topics include:

  • Security (sVirt, SELinux, SECCOMP)
  • Isolation (kernel namespaces, cgroups)
  • Data structures (Kubernetes and Linux)
