While Deployments distribute Pods across nodes based on available capacity, DaemonSets ensure that a copy of a specific Pod runs on all (or selected) worker nodes in the cluster. As nodes are added to or removed from the cluster, DaemonSet Pods are added or garbage-collected automatically.
Operating a multi-cluster architecture introduces a massive observability challenge. If a Kratix Pipeline fails, the logs are in the Platform cluster. If the physical database fails, the logs are in the Worker cluster. In this episode, we build a centralized monitoring stack using Prometheus and Grafana.
Observability allows engineers to infer the internal state of a complex distributed system based on its external outputs. For the KCNA exam, you must understand the Three Pillars of Observability and the CNCF tools that collect them.
