kubectl run my-pod --image=nginx --namespace=my-namespace
# Expose the Pod as a Service
kubectl expose pod my-pod --port=80 --namespace=my-namespace
# Scale the Deployment
kubectl scale deployment my-deployment --replicas=3 --namespace=my-namespace
# Check Pod logs
kubectl logs my-pod --namespace=my-namespace
# Describe a resource
kubectl describe pod my-pod --namespace=my-namespace

6. Get Hands-on Experience

Practical experience is crucial for the CKA exam. Create your Kubernetes cluster using tools like Minikube, Kind, or K3s. Experiment with different scenarios and practice deploying various types of workloads.
