Mastering Kubernetes: A Collection of Hands-On Challenges

Kubernetes has become the de facto standard for container orchestration, revolutionizing the way developers and DevOps teams manage and deploy applications. This collection of Kubernetes challenges from LabEx.io offers a comprehensive learning experience, guiding you through various aspects of this powerful platform. 🚀

1. Kubernetes Resource Monitoring

Kubernetes Resource Monitoring introduces you to Prometheus, an open-source instrumentation framework that can absorb massive amounts of data every second, making it well-suited for monitoring complex workloads in Kubernetes.

2. Running Containers in Pods (Challenge)

Running Containers in Pods (Challenge) delves into the fundamentals of Kubernetes Pods, the smallest and simplest unit in the platform. You'll learn how to run containers in Pods, which provides benefits such as better resource utilization, easier scaling, and more efficient deployment. 🐳

3. Kubernetes Run Command (Challenge)

The Kubernetes Run Command (Challenge) explores the kubectl run command, which is used to create and manage deployments, jobs, and other resources in Kubernetes. You'll discover how to use this command for various use cases, from simple to complex scenarios.

4. Kubernetes Client and Server Version (Challenge)

Kubernetes Client and Server Version (Challenge) teaches you how to print the client and server version information on Kubernetes, which can be useful for troubleshooting and understanding the version of Kubernetes running in your environment. 🔍

5. Kubernetes Service Account

Kubernetes Service Account introduces you to the Kubernetes Service Account, a mechanism for authenticating with the Kubernetes API server. You'll start with simple examples and progress to more complex ones to gain a comprehensive understanding of Service Accounts.

6. Configuring Apps with Secrets (Challenge)

Configuring Apps with Secrets (Challenge) focuses on using Kubernetes Secrets to securely manage sensitive information, such as passwords, API keys, and other confidential data. You'll create a secret, use it in your application, and verify that the application is properly configured. 🔒

7. Isolating Workloads with Namespaces (Challenge)

Isolating Workloads with Namespaces (Challenge) explores how Kubernetes namespaces can be used to isolate workloads and resources within a cluster. You'll create a namespace, deploy a simple web application, and verify that the application is isolated from other resources in the cluster. 🧱

8. Kubernetes Create Command (Challenge)

The Kubernetes Create Command (Challenge) focuses on the kubectl create command, which is used to create Kubernetes resources. You'll learn how to use this command to create resources based on YAML or JSON resource definition files.

9. Role-Based Access Control on Kubernetes (Challenge)

Role-Based Access Control on Kubernetes (Challenge) delves into the world of Role-Based Access Control (RBAC) in Kubernetes. You'll learn how to use RBAC to control access to resources and operations within a Kubernetes cluster, ensuring secure and controlled access for users, groups, and service accounts. 🔐

Dive into these Kubernetes challenges and elevate your skills as a Kubernetes practitioner. Happy learning! 🎉
