Introduction-to-Kubernetes-and-Cloud-Native-Technologies

Module 10: Next Steps and Certification Prep


In Module 9, we learned how to monitor Kubernetes applications using Prometheus and Fluentd. Congratulations on reaching the final module of this course! Now, we’ll focus on your next steps, including preparing for the Kubernetes and Cloud Native Associate (KCNA) certification, exploring career paths in cloud-native technologies, and discovering resources to keep learning. By the end of this module, you’ll have a clear roadmap to continue your cloud-native journey.

Learning Objectives:


What is the KCNA Certification?

The Kubernetes and Cloud Native Associate (KCNA) certification, offered by the Cloud Native Computing Foundation (CNCF) and Linux Foundation, is an entry-level exam that validates foundational knowledge of Kubernetes and cloud-native technologies. It’s perfect for beginners like you, testing concepts covered in this course.

KCNA Exam Details:

Analogy: Think of the KCNA as a driver’s license for Kubernetes. It proves you understand the basics of driving the Kubernetes “car” and navigating the cloud-native “city” (our analogy from Module 1).


Preparing for the KCNA

To prepare for the KCNA, focus on reinforcing the concepts from this course and practicing with hands-on labs. Here’s a step-by-step plan:

Review Course Concepts:

Practice with Hands-On Labs:

Study KCNA Resources:

Take Practice Exams:

Tips:


Career Paths in Cloud-Native Technologies

Kubernetes and cloud-native skills open doors to various roles. Here are some beginner-friendly paths:

Next Certifications:

Analogy: The KCNA is your learner’s permit. With practice, you can upgrade to a full license (CKA/CKAD) to drive bigger Kubernetes projects.


Hands-On Exercise: Review and Explore Resources

This exercise reinforces course concepts and prepares you for the KCNA by exploring resources and reviewing key terms.

Review Key Concepts:

  1. Revisit one quiz from Modules 1-9 (e.g., Module 5 on deployments and services).
  2. Write down definitions for: pod, deployment, service, persistent volume claim, Prometheus.
  3. What to expect: Clarity on core concepts to solidify your understanding.

Explore KCNA Resources:

  1. Visit the KCNA page (https://www.cncf.io/training/certification/kcna/) and review the exam topics.
  2. Check the CNCF Landscape (https://landscape.cncf.io/) and find one new tool (e.g., Jaeger for tracing).
  3. What to expect: Familiarity with the exam structure and additional cloud-native tools.

Try a Mini-Lab:

  1. Go to Killercoda (https://killercoda.com/playgrounds/scenario/kubernetes).
  2. Deploy a simple Nginx pod: kubectl run nginx --image=nginx --restart=Never
  3. Check its status: kubectl get pods
  4. Delete it: kubectl delete pod nginx
  5. What to expect: A quick refresher on kubectl commands.

Note for Beginners: This exercise is lightweight to focus on review and exploration. If you’re not ready for hands-on, just browse the KCNA website and note key terms.
