Over the years, many graphical user interfaces have appeared for Kubernetes, but only a few continue to be actively maintained and developed. While I prefer the standard kubectl CLI for basic interactions with a Kubernetes (k8s) cluster, a visual representation can be extremely helpful for troubleshooting and debugging.
Headlamp was my go to UI tool for k8s, which provides a simliar user experience to many of the previous Kubernetes visualization tools, nothing fancy but it gets the job done.
I recently discovered another OSS Kubernetes visualization tool called Radar, which aims to fill some of the gaps left by existing tools on the market. I was a bit skeptical as this could just be another "modern" tool until the next one is built, but I figured I would give it a try!
At first glance, it has a much cleaner, modern look and feel after I connected it to my vSphere Kubernetes Service (VKS) cluster. The homepage provides a summary of all the expected datapoints including versioning, resource utilization, deployment details, and the health of components and workloads.
