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.
7. Focus on Networking and Security Concepts
Networking and security are significant aspects of managing Kubernetes clusters. Understand how Services, Ingress, and Network Policies work, and learn how to secure your cluster using RBAC and Pod Security Policies.
8. Review Cluster Maintenance and Troubleshooting
Be prepared to troubleshoot common issues that may arise in a Kubernetes cluster. Practice debugging and resolving problems related to Pods, Services, and other components.
