Managing Container Storage with Kubernetes Volumes

Introduction

Kubernetes volumes offer a simple way to mount external storage to containers. This lab will test your knowledge of volumes as you provide storage to some containers according to a provided specification. This will allow you to practice what you know about using Kubernetes volumes.

Additional Resources

Your company, BeeBox, is developing some applications that have storage needs beyond the short-lived storage of the container file system. One component, a simple maintenance script, needs to be able to interact with a directory on the host file system. Another needs to be able to share data between two containers in the same Pod.

Discovering Pod Resource Usage with Kubernetes Metrics

Introduction

Kubernetes metrics allow you to gain insight into a wide variety of data about your Kubernetes applications. You can use these metrics to gain insight into how your compute resources are being used. In this lab, you will have the opportunity to hone your skills by investigating existing pods running in a Kubernetes cluster to determine which ones are using the most CPU.

Additional Resources

You are working for BeeBox, a company that provides regular shipments of bees to customers. The company is in the process of building a Kubernetes-based infrastructure for some of their software.

Controlling Access in Kubernetes with RBAC

Introduction

Role-based access control is an important component when it comes to managing a Kubernetes cluster securely. The more users and automated processes there are that need to interface with the Kubernetes API, the more important controlling access becomes. In this lab, you will have the opportunity to practice your skills with the Kubernetes RBAC system by implementing your own RBAC permissions to appropriately limit user access.

Backing up and Restoring Kubernetes Data in etcd

Introduction

Backups are an important part of any resilient system. Kubernetes is no exception. In this lab, you will have the opportunity to practice your skills by backing up and restoring a Kubernetes cluster state stored in etcd. This will help you get comfortable with the steps involved in backing up Kubernetes data.

Additional Resources

You are working for BeeBox, a subscription service company that provides weekly shipments of bees to customers. The company is using Kubernetes to run some of their applications, and they want to make sure their Kubernetes infrastructure is robust and able to recover from failures.

Building a Kubernetes 1.27 Cluster with kubeadm

Introduction

This lab will allow you to practice the process of building a new Kubernetes cluster. You will be given a set of Linux servers, and you will have the opportunity to turn these servers into a functioning Kubernetes cluster. This will help you build the skills necessary to create your own Kubernetes clusters in the real world.

Additional Resources

Your company wants to transition to a Kubernetes-based infrastructure for running their containerized applications. In order to do that, they will need a basic Kubernetes cluster to get started.

Performing a Kubernetes Upgrade with kubeadm

Introduction

When you are managing Kubernetes in the real world, it is essential that you are able to keep your cluster up to date. This lab will allow you to practice the process of upgrading a Kubernetes cluster to a newer Kubernetes version using kubeadm. This will ensure you are comfortable with the upgrade process and ready to manage real-world Kubernetes clusters.

Additional Resources

You are working for BeeBox, a subscription service company that provides weekly shipments of bees to customers. The company is using Kubernetes to run some of their applications, but a new version of Kubernetes has been released.
