Kubernetes, as a Circuit: 8 Zones, 32 Building Blocks, One Cluster

An attributed summary of a LinkedIn post by Turf Dev (published November 8, 2026). The map and the framing are theirs; the notes below are my summary. See the original post for the full discussion.

Kubernetes as a circuit: 8 zones, 32 building blocks, one cluster — animated map by Turf Dev

Animated map: "Kubernetes, as a Circuit" by Turf Dev, embedded from the original LinkedIn post.

Kubernetes feels big when you start. Turf Dev's map cuts it down to one flow: you run kubectl apply, the API Server checks who you are and what you are allowed to do, the Control Plane decides, and a Worker Node runs it. Everything else in the map exists to make that flow reliable, secure, and observable.

The 8 zones

API Server checks — Authentication, Authorization (RBAC), Admission. This is the gate every request passes through before anything else happens.

1. Control Plane — API Server, etcd, Scheduler, Controller Manager. The brain: it stores the desired state, decides where work goes, and drives the cluster toward that state.

2. Worker Nodes — kubelet, kube-proxy, container runtime. The hands: they run the containers, report status back, and wire up the networking for each pod.

3. Workloads — Pod, Deployment, StatefulSet, Jobs & CronJobs. What you actually run, from a single pod to a scheduled batch job.

4. Config — ConfigMap, Secret, Namespaces, Resource Limits. How you separate environments and keep settings and credentials out of your container images.

5. Networking — Service, Ingress, NetworkPolicy, CoreDNS. How pods find each other, how traffic gets in, and how you fence it off.

6. Scale & Schedule — HPA, Cluster Autoscaler, Node Affinity, Taints & Tolerations. How the cluster grows, shrinks, and decides which node a pod lands on.

7. Security — RBAC, Pod Security, Security Context, Service Accounts. Who can do what, and what a pod is allowed to do once it is running.

8. Observability — Probes, Events, Metrics, Logs. How you know the cluster is healthy — and where to look first when it is not.

How to use the map

The beginner tip from the post is the right one: do not try to learn all 32 blocks at once. Start with Pod, Deployment, and Service, then add one zone at a time. A practical way to use the map after that: when something breaks, the zone tells you where to look. A pod that never starts is usually a scheduling problem (zone 6) or a config problem (zone 4); a service you cannot reach is usually networking (zone 5); a deploy that gets rejected is usually the API Server checks or RBAC (zones 7 and the gate at the top).
