I'm building on-prem kubernetes cluster and we are a windows shop. If we have AD.com as our corporate AD DNS Server, should we use the same namespace for the kubernetes cluster?
My "hunch" is that I should create a separate domain for the cluster and then setup domain forwarding.
Ex.
Any best practices advice?
You probably want to set them up separately. Setting up cluster.local in AD will probably lead to unpredictable results.
cluster.local is a domain for Kubernetes to resolve names 'internally' in a cluster.
Hope it helps!
