Concept and Usage

Port forwarding allows you to access a service running in a Kubernetes cluster from your local machine. This is useful for debugging purposes or to access a service that is not exposed to the public internet. 
My Laptop: kubectl port-forward (8080) → Cluster resource port

​
Commands

kubectl port-forward <resource-type>/<name> <local-port>:<resource-port>

# Examples
kubectl port-forward pod/my-pod 8080:80
kubectl port-forward deployment/my-deployment 8080:80
kubectl port-forward service/my-service 8080:80
In the examples above, the local port is 8080 and the cluster resource port is 80. After running the command, you can access the service at http://localhost:8080.
