Port Forwarding

To connect to a pod, you can

  • use services (using kubectl expose pod <podName> to expose the pod's IP), OR
  • connect to the pod directly using port forwarding (e.g. for testing/debugging).

Forwarding a local network port

To port a local network port to a port in the pod:

# kubectl port-forward <podName> <localPort>:<podPort>
kubectl port-forward kubia-manual 8888:8080
# Forwarding from 127.0.0.1:8888 -> 8080
# Forwarding from [::1]:8888 -> 8080

You can then connect to the pod:

curl localhost:8888
# You've hit kubia-manual
