Kubernetes DaemonSet Generator
Generate DaemonSet manifests to ensure a copy of a specific Pod runs on all (or some) Nodes. Ideal for logging agents, monitoring daemons, and storage plugins.
Kubernetes DaemonSet Generator
Overview
Generate Kubernetes DaemonSet manifests. A DaemonSet ensures that all (or some) Nodes run a copy of a Pod. As nodes are added to the cluster, Pods are added to them. As nodes are removed from the cluster, those Pods are garbage collected.
Frequently Asked Questions
When should I use a DaemonSet instead of a Deployment?
Use DaemonSets for cluster-level background tasks that must run on every node. Common examples include log collection daemons (Fluentd, Logstash), node monitoring daemons (Prometheus Node Exporter, Datadog agent), and cluster storage daemons (Glusterd, Ceph).
Why use hostNetwork or hostPID in a DaemonSet?
Certain monitoring or networking agents (like Calico or Datadog) need to inspect host-level metrics or route host traffic. Enabling hostNetwork or hostPID grants the container access to the node's namespace, but this is a significant security risk and requires privileged mode.
