  "title": "Docker & Kubernetes \u2014 Containers, Clusters and YAML Hell",
  "description": "Emma and Ryan go deep on Docker and Kubernetes \u2014 what a container actually is under the hood (Linux namespaces, cgroups, OverlayFS), how Dockerfile layer caching works, Docker networking, and why Docker alone isn't enough at scale. Then: the full Kubernetes architecture (API server, etcd, scheduler, controller manager, kubelet), core primitives (Pod, Deployment, Service, ConfigMap, Ingress), rolling deployments step by step, K8s networking with CNI plugins, and an honest take on when you don't need K8s at all.",
