What is Kubernetes ?

CKA Exam Kubernetes

Kubernetes, also referred to as “kube” or “k8s,” is software that automatically manages, scales, and maintains multi-container workloads in desired states.

Why use Kubernetes?

One of the benefits of Kubernetes is that it makes building and running complex applications much simpler. Here’s a handful of the many Kubernetes features:

  1. Standard services like local DNS and basic load-balancing that most applications need, and are easy to use.
  2. Standard behaviors (e.g., restart this container if it dies) that are easy to invoke, and do most of the work of keeping applications running, available, and performant.
  3. A standard set of abstract “objects” (called things like “pods,” “replicasets,” and “deployments”) that wrap around containers and make it easy to build configurations around collections of containers.
  4. A standard API that applications can call to easily enable more sophisticated behaviors, making it much easier to create applications that manage other applications.

What Is CKA (Certified Kubernetes Administrator) Exam?

The official CNCF certification page says :

The purpose of the Certified Kubernetes Administrator (CKA) program is to provide assurance that CKAs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes administrators.

CKA Certification Preparation Guide

This section will go over resources and links that can help you prepare for the CKA exam and pass the CKA certification with very good score.

CKA Exam Prerequisites

CKA does not require any candidate to have any other certification before they can appear for the CKA exam. The only thing required to clear the exam is a conceptual and practical understanding of Kubernetes’s components and native objects. Also a lot of hands-on practice.

Personally I preferred to start with CKAD as it offers a narrower focus and a good foundation for understanding Kubernetes. Others might prefer diving into CKA directly, especially if they have experience with Kubernetes administration.

CKA Practice Labs

The best way to prepare for the CKA Certification exam is to get a clear understanding of the concepts involved and do a lot of hands-on practice.

Even if you’re actively working in Kubernetes production environments, you’ll still need to practice to pass the exam

The CKA exam doesn’t include multiple-choice questions, so hands-on practice is essential

The Practice Labs are a great way to reinforce your learning and increase your confidence in taking the CKA exam.

Top 7 CKA exam tips and tricks

Practice , Practice , Practice …

This exam is hands-on in nature, emphasizing the importance of proficiency with the Kubernetes command line interface (kubectl).

My advices are :

Cultivate a high level of comfort and familiarity with kubectl, practicing the art of typing commands swiftly and accurately.

Enroll in the two killer,sh, hands-on sessions and aim for outstanding scores in order to thoroughly prepare yourself before attempting the actual exam.

Make sure to practice using Vim as it is a crucial tool for the CKA exam. The exam environment does not offer IDEs like VSCode, so being proficient in Vim will greatly expedite your task-solving abilities.

Use the short name of K8s Resources

Short nameFull name

Useful commands or parameters during the exam

# Use "kubectl describe" for related events and troubleshooting
kubectl describe pods <podid>

# Use "kubectl explain" to check the structure of a resource object.
kubectl explain deployment --recursive

# Add "-o wide" in order to use wide output, which gives you more details.
kubectl get pods -o wide

# Check always all namespaces by including "--all-namespaces"
kubectl get pods --all-namespaces

# Show labels for all pods (or any other Kubernetes object that supports labelling)
kubectl get pods --show-labels

# create a service
kubectl create service clusterip my-service --tcp=8080 --dry-run=client -o yaml

# create a deployment
kubectl create deployment nginx --image=nginx --dry-run=client -o yaml

# create a pod
kubectl run nginx --image=nginx --restart=Never --dry-run=client -o yaml

Use dry run to generate yaml

During the exam, creating K8s resources like pods, deployments, and services from scratch can be time-consuming and challenging to remember their entire structure. To simplify this process, you can use the “dry run” feature to generate a basic YAML file. Then, modify the generated file as needed before using it to create the required resources.

For instance, to address the question of creating an nginx pod with specific resource limits (memory: 1M, CPU: 500m), follow these commands:

Generate the YAML file with dry run:

k run nginx --image=nginx --dry-run=client -o yaml > pod.yaml

Modify the “pod.yaml” file to add the resource limit settings.

Create the pod using the modified YAML file:

k create -f pod.yaml

To save time on input, you can define a shell variable for the --dry-run=client -o yaml option like this:

export do="--dry-run=client -o yaml"

Then, you can use the defined variable in the command like this:

k run nginx --image=nginx $do > pod.yaml

By employing the “dry run” and shell variable approach, you can efficiently create K8s resources and manage their configurations during the exam.

Time management

Since you will be executing the kubectl command multiple times, setting up aliases can save you valuable seconds with each entry. For instance, assigning an alias like ‘k’ for ‘kube-control’ can potentially grant you an additional minute or two towards the end of the exam

alias k=kubectl

Review Completed Tasks

After each question, it is crucial to review your work meticulously to ensure accuracy. Avoid the risk of spending 10-15 minutes on a question and unintentionally overlooking potential errors

For example, if you have made changes to the kubelet during a task, it is highly recommended to check its status before moving on to another task. This verification step ensures that the kubelet is functioning as expected after the modifications. To check the kubelet’s status, use the following command:

systemctl status kubelet

Stress Management

You will be able to complete the exam in 2 hours.
PLEASE DON’T get panic because :

  • First: if it is your first attempt then you have the other left.
  • Second: is that you only need 66 % to crack the exam 🙂

Configuration Management during the Exam

As mentioned previously, the CKA exam environment consists of six clusters, each with its own dedicated set of nodes. It is essential to emphasize the significance of switching contexts correctly between these clusters before attempting any tasks in the exam.

One common mistake individuals make is performing actions on the wrong cluster. To avoid this, ensure that you carefully switch the context to the intended cluster before executing any commands or tasks. Paying close attention to this detail will help maintain accuracy throughout the exam and prevent errors caused by working on the wrong cluster

At the start of each task you’ll be provided with the command to ensure you are on the correct cluster to complete the task , for example :

kubectl config use-context k8s

An example of command to ssh to a master node during a kubernetes cluster update :

ssh mk8s-master-0 

Us elevated privileges on the master node :

sudo -i
