Problem statement:
Currently we are running k8s in multiple environments e.g. dev, uat,staging. It becomes very difficult to identify for us just by looking at k8s dashboard UI. Do we have any facility to customize k8s dashboard indicating somewhere in header or footer cluster or environment we are using?
Since K8S is open source, you should have the ability to do whatever you want. You will ofcourse need to play with the code and build you own custom dashboard image.
You can start off from here
