You want to access two different pods pod-a and pod-b running on ports 8080 and 9090 respectively, on your local machine at ports 3000 and 4000 simultaneously. Which commands should you run?
Step 1: Understand port-forward syntax and concurrency
Each port-forward command forwards one pod port to a local port. To run two simultaneously, run two commands in parallel using & or separate terminals.
Step 2: Verify port mappings
Local port 3000 maps to pod-a's 8080, and local 4000 maps to pod-b's 9090. The syntax is localPort:remotePort.
Step 3: Check command correctness
kubectl port-forward pod/pod-a 3000:8080 & kubectl port-forward pod/pod-b 4000:9090 correctly runs two commands in background with correct port mappings. kubectl port-forward pod/pod-a 3000:8080; kubectl port-forward pod/pod-b 4000:9090 runs sequentially, blocking second command.
