Creates a pod called echo that listens on port 8080, echoing everything it receives.
kubectl run echo --image=busybox -- nc -lk -p 8080 -e cat
To test it out, you can do this, to listen on local port 8080 and forward all connections to the echo pod:
kubectl port-forward echo 8080:8080
| kubectl run tcpecho --image=alpine --restart=Never -- /bin/sh -c "apk add socat && socat -v tcp-listen:8080,fork EXEC:cat" |
