DaemonSets are a great way to ensure a pod replica runs dynamically on each node. They even automatically handle the creation and removal of such pods when nodes join or leave the cluster. In this lab, you will have the opportunity to practice your skills with DaemonSets by using them to run pods on all nodes in an existing cluster.
Successfully complete this lab by achieving the following learning objectives:
- Create a DaemonSet Specification YAML File
Create a file called
daemonset.ymlwith a DaemonSet YAML specification. Use the provided pod specification in the DaemonSet template.
- Create the DaemonSet in the Cluster
Use your specification YAML file to create the DaemonSet in the cluster. Verify each worker node is running a copy of your pod and the DaemonSet pods are all running.
