I am struggling to understand how to access my service from the outside of Kubernetes?!?!? What is the network address? I understand it creates dynamic IP but how does the rest of the net identify and connect to it? Its is not in the networks known routing tables, just in the guest host!?!?! Most of this makes sense (and is very cool) but cannot wrap my head around networking and how to make my service avail from outside the cluster with the virtual ip?

Any help is much appreciated as I am starting to work with a product that runs on k8s and I am sooo close to getting it up and running :slight_smile:

Thank you in advance.

You can format your yaml by highlighting it and pressing Ctrl-Shift-C, it will make your output easier to read.

Can you post your service or deployment definition yaml?

Does that help at all?
