Kubernetes DaemonSet: Practical Guide to Monitoring in Kubernetes

A Kubernetes DaemonSet is a workload controller that ensures a copy of a pod runs on either all or some specified nodes within the cluster, making it ideal for tasks like monitoring, logging, or running network proxies on every node. It provides a hands-off, automated solution to maintain operational awareness across all nodes, ensuring no node goes unmonitored and enhancing the reliability and performance of Kubernetes clusters. DaemonSets simplify the process of maintaining a high level of operational awareness by automating the deployment and lifecycle management of monitoring tools on each node, providing accurate and localized data about network traffic, scalability and reliability, and security and isolation.
