Description of problem: Our example DU policy runs the PTP daemon on workers and masters. This is fine for SNO and 3-node clusters, where all workers are also masters, but not correct for standard clusters, where only workers should be running PTP. How reproducible: 100% Steps to Reproduce: 1. Deploy a standard cluster and DU profile with ZTP 2. Check where the ptp daemon pods are running Actual results: The PTP daemon is running on all nodes Expected results: The PTP daemon is only running on worker nodes Additional info: This can be accomplished by adding the following to the PtpOperatorConfig spec: > daemonNodeSelector: > node-role.kubernetes.io/worker: ""
