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.

  1. 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!

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. Challenge

    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.
