Creating and managing DaemonSets
In order to demonstrate how DaemonSets work, we will use Fluentd Pods. Fluentd is a popular open-source log aggregator that centralizes log data from various sources. It efficiently collects, filters, and transforms log messages before forwarding them to different destinations for analysis and storage.
To access the DaemonSet endpoints, we will use a headless service, similar to what we did for StatefulSet in Chapter 12, StatefulSet – Deploy Stateful Applications. Most of the real use cases of DaemonSets are rather complex and involve mounting various system resources to the Pods. We will keep our DaemonSet example as simple as possible to show the principles.
If you would like to work on another example of a DaemonSet, we have provided a working version of Prometheus node-exporter deployed as a DaemonSet behind a headless Service: node-exporter.yaml. When following the guide in this section, the only difference is that you need...
