  2. Introduction to Kubernetes Metadata • Content: • Kubernetes objects (Pods, Deployments, Services, etc.) often need metadata. • Metadata helps in organizing, selecting, and managing resources. • Two key metadata types: • Labels • Annotations +91-7032290546 www.visualpath.in

  3. What are Labels in Kubernetes? • Content: • Labels are key/value pairs attached to Kubernetes objects. • Used to organize and select subsets of objects. • Common use cases: • App versioning (app=nginx, version=v1) • Environment separation (env=prod, env=dev) +91-7032290546 www.visualpath.in

  4. Use Cases of Labels • Content: • Service discovery (Services select Pods using labels) • Rollouts and updates (Label-based deployments) • Monitoring and alerting (Group by labels in tools like Prometheus) • CI/CD pipelines (Label for stages or environments) +91-7032290546 www.visualpath.in

  5. What are Annotations in Kubernetes? • Content: • Annotations are also key/value pairs, but meant for non-identifying metadata. • Provide additional information not used for selection. • Examples: • Tooling data (e.g., last deployment time) • Contact info for object owners • Debug logs, URLs, or checksum data +91-7032290546 www.visualpath.in

  6. Differences Between Labels and Annotations +91-7032290546 www.visualpath.in

  7. How to Use Labels & Annotations (YAML Example) yaml CopyEdit apiVersion: v1 kind: Pod metadata: name: mypod labels: app: nginx env: dev annotations: description: "This pod runs a dev version of nginx" owner: "team@example.com" +91-7032290546 www.visualpath.in

  8. Best Practices Content: • Use standardized naming for consistency (team, env, version) • Avoid storing sensitive data in annotations • Keep labels lightweight for performance in selectors • Use annotations for tools, audits, and documentation +91-7032290546 www.visualpath.in

  9. Summary Content: • Labels and Annotations are vital for managing Kubernetes objects. • Labels help in selection and grouping. • Annotations store extra metadata not used by Kubernetes directly. • Apply them smartly to improve automation, monitoring, and maintainability. +91-7032290546 www.visualpath.in
