I am using this command to remote debugging my kubernetes(v1.15.2) pod:

kubectl port-forward soa-room-service-65986bddb4-6cz76 5011:5011

but when I connect the debugging port using my Intellij Idea,it shows:

Forwarding from 127.0.0.1:5011 -> 5011
Forwarding from [::1]:5011 -> 5011
Handling connection for 5011

I search from internet and try to install socat in my local Mac OS Catalina:

brew install socat
$ socat -h
socat by Gerhard Rieger and contributors - see www.dest-unreach.org
Usage:
socat [options] <bi-address> <bi-address>
   options:
      -V     print version and feature information to stdout, and exit

and also install socat in remote server's pod:

RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime \
    && echo $TZ > /etc/timezone \
    && apk add --no-cache curl socat

when I debug,the error still remain,what should I do to fix this problem and enable by kubernetes pod remote debugging? Am I missing something?
