spec.template is one of the required fields in. apiVersion: apps/v1Īs with all other Kubernetes config, a DaemonSet needs apiVersion, kind, and metadata fields. A sample DaemonSet file is provided below. You can create a DaemonSet using a YAML file. Use a DaemonSet when it is important that a copy of a Pod always run on all or certain hosts, if the DaemonSet provides node-level functionality that allows other Pods to run correctly on that particular node. Use a Deployment for stateless services, like frontends, where scaling up and down the number of replicas and rolling out updates are more important than controlling exactly which host the Pod runs on.

running a node monitoring daemon on every nodeĭaemonSets are similar to Deployments in that they both create Pods, and those Pods have processes which are not expected to terminate (e.g.running a logs collection daemon on every node.running a cluster storage daemon on every node.Deleting a DaemonSet will clean up the Pods it created. As nodes are removed from the cluster, those Pods are garbage collected. As nodes are added to the cluster, Pods are added to them. What is a DaemonSetĪ DaemonSet ensures that all (or some) Nodes run a copy of a Pod. We will explore what they are, when they are used and how we can deploy our very own Daemon Set in a Kubernetes Cluster. Hello there! In this blog post, we are going to discuss Kubernetes Daemon Sets.
