Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. This is one of the technologies almost every company is implementing or trying to adopt nowadays. The Linux Foundation offers two certifications on this technology: Certified Kubernetes Application Developer (CKAD) and Certified Kubernetes Administrator (CKA). I recently took both exams. A lot of people reached out to me and asked for tips. So, I wanted to share tips that are helpful while preparing the exam and during the exam as well.

1. Practice

For the CKA exam, Along with the CKAD preparation you need to understand how to create a multi-node cluster and how to switch between clusters, debugging a failure node, Taints, and tolerations, RBAC Authentication, etc are very important.

2. Practice Practice Practice

3. Always remember to change your cluster

4. Kubernetes The Hard Way

5. Use Kubectl every time

// create YAML with dry-run flag
kubectl run nginx --image=nginx --restart=Never --dry-run -o yaml > nginx-pod.yaml
// cat nginx-pod.yaml
apiVersion: v1
kind: Pod
metadata:
creationTimestamp: null
labels:
run: nginx
name: nginx
spec:
containers:
- image: nginx
name: nginx
resources: {}
dnsPolicy: ClusterFirst
restartPolicy: Never
status: {}
// create a pod
kubectl create -f nginx-pod.yaml

6. Use the Kubectl cheatsheet

8. Skip questions you are not familiar
