Cluster Info | A Kubernetes Client Monitor

https://github.com/scubakiz/clusterinfo
A container-based Kubernetes client that monitors a Kubernetes namespace and graphically shows various resources with their current states. Unlike Lens, Cluster Info shows resources in context, like pods within replica sets, which are within deployments, and which nodes are hosting which pods.

The primary purpose of Cluster Info is as a training aid to demonstrate Kubernetes concepts during workshops.

Cluster Info | A Kubernetes Client Monitor

https://github.com/scubakiz/clusterinfo
Cluster Info is an in-cluster Kubernetes UI designed for teaching Kubernetes concepts. I designed and developed the project to aid in my deliveries of Kubernetes workshops. By animating object transitions between states, the app helps students understand complex Kubernetes concepts easier.

Kubernetes Training UI

https://scubakiz.github.io/clusterinfo/
Cluster Info is an educational tool. It's meant to show you an overview of your Kubernetes cluster without all the details you don't need, but you can get by running the describe command.

Cluster Info is unique because it provides context to how resources interact with each other rather than being just a graphical version of Kubectl, line Lens.
