Manage Kubernetes Controllers and Deployments
In this lab, you’ll practice how to manage the Kubernetes api server and pods. When you’re finished, you’ll have the required knowledge to interact with the Kubernetes api server, the anatomy of the requests, and how to manage pods using labels and probes.

Challenge
Get Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
-
Challenge
Inspect Kubernetes Controllers
Even in its simplest installation, Kubernetes makes use of controllers. To start this lab, you will inspect the most common controllers used in the Kubernetes cluster deployed in your lab environment.
-
Challenge
Work with Deployment and ReplicaSet Controllers
The Deployment and ReplicaSet controllers in kubernetes allow you to define a desired state, and the Deployment Controller changes the actual state to the desired one at a controlled rate. In this challenge, you will try out both controllers and use them to rollout and rollback previous versions of your application.

Challenge
Deploy DaemonSet to Ensure Your Application Runs in All Nodes
DaemonSets are used to ensure an application is deployed in all the nodes. This is useful, for example, to ensure log collection agents run on all hosts forming your cluster. You will use a DaemonSet to run an app in all nodes forming your cluster.

Challenge
Create a Stateful Application with StatefulSet
Some applications like databases need persistent storage to provide data durability (application state). Here, you will deploy a caching service using the StatefulSet controller.
-
Challenge
Use Job and CronJob Controllers
Jobs are used to perform a specific task. This controller will keep re-running the pod until it successfully terminates. To finish up the directed portion of the lab, you will deploy a simple Job resource to automate a task, and then you will ensure the task is run on a schedule by using the CronJob controller.

The Last Challenge
Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
