Container Port and Node Port mapping default to open

[cdrage]

When mapping a port, for example:

- "80:80"

in the Docker Compose file. It's the same as simply doing

- "80"

Is this normal? Exposing the ports by default when converting them to a service?

I think so this is normal, because if you don't create a service name resolution wont happen from other pods. And it's safe because services are by default exposed as clusterIP which is not accessible from outside cluster.

Yeah, kind of realized that this issue was me just being a Kubernetes noob :) Closing! Thanks @surajssd
