Exploring Kubernetes on the Edge 11 - CNCF Kubernetes Book Club
Event Date: 2024/08/23
About this book Edge Computing Systems with Kubernetes:
Edge computing is a way of processing information near the source of data instead of processing it on data centers in the cloud. In this way, edge computing can reduce latency when data is processed, improving the user experience on real-time data visualization for your applications. Using K3s, a light-weight Kubernetes and k3OS, a K3s-based Linux distribution along with other open source cloud native technologies, you can build reliable edge computing systems without spending a lot of money. In this book, you will learn how to design edge computing systems with containers and edge devices using sensors, GPS modules, WiFi, LoRa communication and so on.
📊 Prometheus & Grafana Tutorial: Monitoring Your Kubernetes Cluster
In this video, we dive into the world of Prometheus and Grafana for monitoring Kubernetes clusters. We start with an introduction to Prometheus, a time series database, and Grafana, a tool for creating dashboards. We then demonstrate how to install Prometheus and Grafana on a Jetson Nano using Robusta, addressing common installation challenges like PVC issues along the way. The tutorial explores key Prometheus features including configuring monitoring jobs, writing and executing PromQL queries, and visualizing metrics. We also walk through Grafana, showing how to import and customize dashboards, and view Kubernetes resource metrics. The video covers integration with alerting systems like Alert Manager and Slack, and provides tips for learning PromQL and using both tools effectively. Whether you're new to monitoring or looking to enhance your skills, this tutorial offers practical insights for setting up and using Prometheus and Grafana in your Kubernetes environment.
