About the framework

Architecture Diagram for Kubernetes Clusters

This template applies architecture diagram conventions to a standard Kubernetes deployment. The two-tier layout separates the control plane (brain of the cluster) from the worker nodes (where workloads run), matching how K8s actually operates.

The API Server sits at the center of the control plane because every component communicates through it. etcd stores cluster state, the scheduler assigns pods to nodes, and the controller manager ensures desired state matches actual state. On worker nodes, kubelet manages pod lifecycle while kube-proxy handles networking.

Customize by adding an ingress controller, service mesh (Istio), persistent volume claims, or expanding to show a multi-cluster setup with federation.

Frequently asked questions

Common questions

Can I add an ingress controller and load balancer?

Yes. Click 'Use this template' and ask the AI to 'Add an ingress controller and external load balancer.' It will insert them with proper connections showing traffic flow from outside the cluster.

How do I show a specific deployment architecture?

Describe your setup, like 'Show a 3-node cluster with Redis, PostgreSQL, and a Node.js app.' The AI will customize pod labels, add persistent volumes, and show service connections.

Can I expand this to show networking details?

Absolutely. Ask the AI to 'Add CNI plugin, CoreDNS, and service mesh' to see the full networking stack within the cluster.
