Awesome Kubernetes Architecture Diagrams

Kubernetes Icons Set (KIS)

Kubernetes Icons Set provides icons to standardize Kubernetes architecture diagrams for presentation. Having uniform architecture diagrams improve understandibility.

Comparing generated diagrams

Following generated diagrams are based on the official Kubernetes WordPress tutorial. See the used WordPress manifest declaring seven resources: 2 Services, 2 Deployments, 2 PersistentVolumeClaims, and 1 Secret.

KubeDiagrams

Architecture diagram generated from the WordPress manifest:

Strengths:

All seven resources and all their relationships are represented.
Namespace and label-based clustering.

Weaknesses: None.

Architecture diagram generated from a WordPress instance deployed on a Kubernetes cluster:

Strengths:

Cluster resources, i.e., PersistentVolume and Node, are represented.

Weaknesses:

Too many edges to the Secret and PersistentVolumeClaim resources!

KubeView

Architecture diagram generated from a WordPress instance deployed on a Kubernetes cluster:

Strengths:

All resources are represented.

Weaknesses:

2 edges from each pod to the secret are not represented!
2 edges from each pod to the kube-root-ca.crt config map are not represented!
