Jump right into Kubernetes development with career-focused lessons and hands-on practice.

DevOps for Developers

Kubernetes is a powerful container management tool that's taking the world by storm. This detailed course will help you master it.

In this course, you'll start with the fundamentals of Kubernetes and what the main components of a cluster look like. You'll then learn how to use those components to build, test, deploy, and upgrade applications, as well as how to achieve state persistence once your application is deployed. You'll also learn how to secure your deployments and manage resources, which are crucial DevOps skills.

By the time you're done, you'll have a firm grasp on what Kubernetes is, as well as the skills to deploy your own clusters and applications with confidence.

A Practical Guide to Kubernetes

# Authentication
Since John is not around, we'll do some role-playing and impersonate him.
## Configuring kubectl
We’ll  first have to set the cluster using the address and the certificate authority we sent John.

kubectl config set-cluster jdoe \
    --certificate-authority \
    /usercode/certs/keys/server-ca.crt \
    --server $SERVER

We create a new cluster called `jdoe`. 

Please note that the command we executed created just another config entry that enables us to access all resources that currently exist in the cluster. It manipulates the local text file without changing anything in the existing cluster.
## Setting the credentials
Next, we’ll have to set the credentials using the certificate and the key we created for them.
