I use a docker container to interact with my kubernetes cluster. I run kubectl from inside the container. All works fine except when I want to port forward. I can use kubectl port forward to forward from the pod to my container. But then I won't be able to access the site from my laptop browser. I can only curl from inside the container.

Is there any way at all I can access the site from my browser. docker host networking mode isn't supported on Macs and I use a Mac. Any suggestions?

I have this scenario you may adapt for your need :

On my laptop, I run :

docker run -it --rm -p 2222:2222 ubuntu bash

From inside container, I run :

kubectl port-forward --address 0.0.0.0 pod/my-pod-7f66c99ddd-6c429 2222:22

Now this is the diagram for port-forwarding :

      2222             2222                 2222              22
laptop -------------------> docker-container------------------->k8s-pod

Now, in another terminal on my laptop, I can do

ssh -p 2222 user-on-pod@laptop-hostname

to arrive at pod
