I have used netmaker and their netclients inside my kubernetes cluster to have access to all k8s pods over a secure wireguard tunnel. No need to worry about ssl certificates on my admin dashboards for my longhorn, pihole, portainer, linkerd and other admin dashboards. Also, no need to k8s port forward everytime I wanna access a specific service inside the cluster network. Netmaker and kubernetes for secure and manageable cluster network access is unbeatable I think.
