Kubernetes 101 - Episode 10 - Monitoring with Lens, Prometheus, and Grafana

Step-by-Step Tutorial: Monitoring Kubernetes with Lens, Prometheus, and Grafana

1. Introduction to Monitoring Kubernetes:

   • The last episode of the "Kubernetes 101" series focuses on monitoring Kubernetes clusters using tools like Lens, Prometheus, and Grafana.

2. Understanding Lens for Kubernetes:

   • Lens is a tool that provides a graphical interface for managing and monitoring Kubernetes clusters.
   • Install Lens on your computer using Homebrew on Mac or Snap on Linux.
   • Add clusters to Lens by connecting to the Kubernetes API through the kubeconfig file.

3. Exploring Cluster Data with Lens:

   • Use Lens to visualize various resources in your clusters, such as pods, deployments, and namespaces.
   • Monitor pods, view logs, and interact with containers directly within Lens.

4. Setting Up Prometheus and Grafana:

   • Install Prometheus and Grafana using Helm charts to gather metrics and create monitoring dashboards.
   • Enable persistence for Grafana to store configurations and user access settings.

5. Accessing Grafana Dashboards:

   • Access Grafana through a browser by port forwarding the service to localhost.
   • Explore pre-built dashboards in Grafana for monitoring nodes, workloads, and cluster resources.

6. Configuring User Access in Grafana:

   • Set up user access controls in Grafana to manage permissions and access to specific dashboards.
   • Ensure persistence is enabled for Grafana to store user configurations and settings.

7. Prometheus and Grafana Book:

   • Download the free Kubernetes monitoring book created from the "Kubernetes 101" series for further learning and reference.
   • Share the book link with others who might benefit from learning about monitoring Kubernetes clusters.

8. Supporting the Content Creator:

   • Consider supporting the creator through platforms like Patreon or GitHub Sponsors to help maintain and update the educational content.

9. Conclusion:

   • Emphasize the importance of monitoring Kubernetes clusters for efficient management and troubleshooting.
   • Encourage readers to explore the monitoring tools discussed and continue learning about Kubernetes.

By following these steps, you can effectively monitor your Kubernetes clusters using Lens, Prometheus, and Grafana as demonstrated in the video.
