Now that you're ready, use the kubectl port-forward command followed by the name of the pod and the desired local and remote ports. Use the kubectl get pods command to list the available pods in the cluster. Once you are done installing kubectl, identify the pod(s) you want to forward ports from. You need to have kubectl installed and configured to connect to your Kubernetes (K8s) cluster. This functionality allows you to work on troubleshooting network issues, and perform debugging without the need for complex networking setups. Whether you need to interact with a pod, service, or deployment, it simplifies the process by establishing a secure tunnel between your local machine and the desired resource. Kubectl port-foward allows you to access services running within the cluster as if they were running on your local machine. It creates a secure tunnel between your local machine and a pod running within a Kubernetes cluster. “kubectl port-forward” is a powerful command-line tool that allows you to securely access resources running within a cluster. Now that we understand how the generic port forwarding concept in networking works, let’s see how this concept applies in Kubernetes.Īlso Read: What is Internal Developer Platform? What is Kubectl Port Forwarding Once these rules are set up, incoming traffic from the internet is directed to a particular application, allowing external services to access applications running on a network. This tells the router that any requests it receives on a particular port should be directed to a device and application within a network. Port forwarding involves configuring the firewall to allow incoming traffic from and to ports configured to the application endpoints. They act like virtual channels that allow different applications to communicate with the device. The devices also have ports associated with them. However, when you want to access a service on a specific device from the internet, you need to forward the necessary ports.Īlso Read: Kubectl Exec Tutorial How does Port Forwarding Work?Įvery device connected to a network has an IP address, which is an identifier assigned to it. In a local network, devices communicate with each other using private IP addresses that are not accessible from the internet. It involves redirecting the traffic from one particular port on a router to another within the same network. Port forwarding is a technique used in networking to allow all kinds of devices and network components to communicate with applications running on a local network.
