Kubernetes architecture diagram template

A Kubernetes architecture diagram explains how a cluster fits together for people new to it. This example shows the control plane with the API server, etcd, scheduler and controller manager, two worker nodes running kubelet, kube-proxy and pods, an ingress controller for user traffic, a container registry and a persistent volume for stateful pods.

How to use this template

  1. Start with the control plane

    Show the API server at the centre, since every other component talks to it. Add etcd, the scheduler and controllers around it.

  2. Add your nodes and workloads

    Draw the worker nodes and the pods that matter most. Group pods by namespace or service if you have many.

  3. Show traffic and storage

    Draw how users reach the app through ingress, where images come from, and which pods use persistent storage.

Questions about this template

Can I add more worker nodes to the diagram?

Yes. Duplicate a worker node box with its kubelet, kube-proxy, pods and container runtime, then draw its links back to the API server.

Do I need an account to use it?

No. Open the template and edit it in your browser. Your work saves on this device. An account is optional if you want to sync your workspace.

Can I export the finished diagram?

Yes. Use Export in the editor to save a PNG, SVG or PDF, or download an editable .epicdraw backup.
