Kubernetes Proxy Command

Introduction

In this lab, you will learn how to use the Kubernetes proxy command to access the Kubernetes API server from your local machine. You will start with simple examples and gradually increase in complexity until you have a fully functional proxy.

The Kubernetes proxy command allows you to access the Kubernetes API server from your local machine without needing to expose the API server to the public internet. This can be useful for debugging and troubleshooting Kubernetes clusters.

Set Up a Basic Proxy

In this step, you will set up a basic proxy that can forward requests to the Kubernetes API server using the Kubernetes proxy command.

Here is the basic command you will use to set up the proxy:

kubectl proxy

This command will start a proxy server on your local machine that listens on port 8001. You can test the proxy by making a request to http://localhost:8001/api/v1/pods (assuming you have pods running in your cluster).

Access the Kubernetes Api with Curl

Open a new terminal and use the following command to access the API server.

Here is the basic command you will use to access the API server with curl:

curl http://localhost:8001/api/v1/pods

This command will retrieve a list of pods running in your cluster.

Summary

In this lab, you learned how to use the Kubernetes proxy command to access the Kubernetes API server from your local machine. You learned how to set up a basic proxy, access the API server with cURL and Python, authenticate with the API server, and use authenticated requests.
