I would like to know if port-forward blocks other requests to the pod like redis, mongo, etc.
If I use kubectl port-foward command with mongo port for example, the mongo server will not receive the data ?

Can't understand what you are asking... Do you mean to ask if port-forward blocks other requests to the pod when you do it? – night-gold Dec 04 '19 at 09:46

It would make no sense to do `port-forward` for prod environment. – suren Dec 04 '19 at 11:36

As per your comment, kubectl port-forward does not block any exposed traffic to the target pod. So adding portforward won't affect others.
What portforward does is simply making a specific request to the API server. (see doc)
Going further, I don't think port-forward makes pod more "dangerous" (vulnerable against security), however it is generally used for debugging to scope into the pod, not to expose a service in the pod. Use Nodeport service for production.
Plus, port-forward has default timeout setting in kubelet.
