I am attempting to reverse port forward information from a Kubernetes pod 192.168.49.2:30085 to my locoalhost:8000 but I am having issues.

The goal is to get the same response as curl 192.168.49.2:30085 on localhost:8000

One thing I have tried has been using ktunnel with the command ktunnel expose <service_name> 30085:8000 to try to forward this info. Doing this I get the output

INFO[0000] Exposed service's cluster ip is: 10.101.77.99
.INFO[0000] waiting for deployment to be ready
.....
INFO[0001] port forwarding to https://192.168.49.2:8443/api/v1/namespaces/default/pods/thisisatest-59d5584c84-b5qrc/portforward
INFO[0001] Waiting for port forward to finish
INFO[0001] Forwarding from 127.0.0.1:28688 -> 28688
INFO[2022-08-03 20:23:48.605] starting tcp tunnel from source 30085 to target 8000

Which seems normal and I am able to get a response when using curl http://10.101.77.99:30085 on local host 8000 but not the correct response.

I have also attempted to run a tcp server with the command nc 127.0.0.1 8000 | kubectl exec -i <pod_name> tcpserver 127.0.0.1 30085 cat But am having poor results as well. Am I using these services incorrectly? Or is there a better way to do this all together?

  • How is the question related to docker? --- While Stack Overflow does permit certain questions about Kubernetes, we require that they (like all questions asked here) be specifically related to programming. This question does not appear to be specifically related to programming, but network-related, which makes it off-topic here. You might be able to ask questions like this one on [sf] or [DevOps](https://devops.stackexchange.com/). – Turing85 Aug 03 '22 at 21:23
