Kubernetes has become the backbone of modern cloud-native applications, and mastering it is crucial for DevOps and IT professionals. The to Kubernetes LFS158 course is a 20-hour intensive program that equips learners with foundational Kubernetes knowledge, culminating in a certification.
You Should Know: Kubernetes Commands & Practical Steps
1. Basic Kubernetes Commands
- Check Kubernetes cluster status:
kubectl cluster-info
- List all running pods:
kubectl get pods
- Describe a specific pod:
kubectl describe pod <pod-name>
- Delete a pod:
kubectl delete pod <pod-name>
2. Deploying an Application
- Create a deployment:
kubectl create deployment nginx --image=nginx
- Expose a deployment as a service:
kubectl expose deployment nginx --port=80 --type=LoadBalancer
- Check service status:
kubectl get services
3. Scaling and Updates
- Scale a deployment:
kubectl scale deployment nginx --replicas=3
- Update a deployment (rolling update):
kubectl set image deployment/nginx nginx=nginx:1.19
4. Troubleshooting
- View pod logs:
kubectl logs <pod-name>
- Access a shell inside a pod:
kubectl exec -it <pod-name> -- /bin/bash
What Undercode Say
Kubernetes is a powerful orchestration tool, and mastering it requires hands-on practice. The LFS158 course provides a solid foundation, but real expertise comes from deploying, scaling, and troubleshooting real-world applications. Key takeaways:
– Use `kubectl` extensively for cluster management.
– Practice deploying multi-container applications.
– Learn Helm for Kubernetes package management.
– Explore monitoring tools like Prometheus & Grafana.
