Kubectl Proxy & Port Forward

In this section, we will take a look at Kubectl Proxy & Port Forward.

  • Kubectl handles locating and authenticating to the apiserver. If you want to directly access the REST API with a http client like curl or wget, or a browser, there are several ways to locate and authenticate:

    • Run kubectl in proxy mode.
    • Uses stored apiserver location.
    • Verifies identity of apiserver using self-signed cert.

Using kubectl proxy

The following command runs kubectl in a mode where it acts as a reverse proxy. It handles locating the apiserver and authenticating.

kubectl proxy --port=8080

Using kubectl port-forward

kubectl port-forward allows using resource name, such as a pod name, to select a matching pod to port forward to.

kubectl port-forward service/nginx 28080:80
