Hi there, what would be the best way of accessing stuff the same way as Pods in the cluster would. I am implementing SSO functionality using OpenID Connect and both my application and I need to reach the SSO service (also in cluster) using the same address. It seems like I can't reach the cluster IP from the host machine (I am on macOS, enforced firewall from work)

You need to use either a nodeport or loadbalancer service if you want to connect from outside the cluster.

I already do that, problem is, that me connecting via the NodePort (http://localhost:<nodeport>) is different than what my application would use to connect to that same service.

Inside the cluster you have to use the full FQDN or use a service mesh, but accessing from outside to cluster ip, you have to port forward it.
