- Practice building and deploying containerized applications.
- Recommended resources:
3. Cloud-Native Principles
- Study microservices architecture.
- Understand 12-factor app methodology.
- Learn about service meshes like Istio and Linkerd.
Step 3: Hands-On Practice
1. Set Up a Kubernetes Environment
- Use tools like Minikube or Kind (Kubernetes IN Docker) to create a local Kubernetes cluster.
- Explore managed Kubernetes services (GKE, EKS, AKS).
2. Deploy Sample Applications
- Deploy simple applications using YAML configuration files.
- Practice scaling and updating applications.
- Experiment with Kubernetes resources like ConfigMaps and Secrets.
3. Monitoring and Logging
- Install Prometheus and Grafana for monitoring.
- Set up Fluentd or Elastic Stack for centralized logging.
Step 4: Advanced Topics
1. Security and Networking
- Study Kubernetes network policies.
- Learn about role-based access control (RBAC) and security contexts.
- Understand container image scanning tools (e.g., Trivy, Clair).
2. Application Lifecycle Management
- Learn about CI/CD pipelines using tools like Jenkins, ArgoCD, and FluxCD.
- Practice rolling updates and canary deployments.
3. Cloud-Native Ecosystem
- Familiarize yourself with tools like Helm, Kustomize, and Knative.
- Study serverless computing and its integration with Kubernetes.
Step 5: Practice Mock Exams
1. Sample Questions
- Solve sample KCNA exam questions available on the Linux Foundation’s website.
2. Timed Practice
- Take full-length practice tests under timed conditions to build exam readiness.
3. Review and Improve
- Analyze your weak areas and revisit those topics.
Study Tips for Success
