8.2. Automated discovery of PTP network devices

The PTP Operator adds the NodePtpDevice.ptp.openshift.io custom resource definition (CRD) to OpenShift Container Platform. The PTP Operator will search your cluster for PTP capable network devices on each node. The Operator creates and updates a NodePtpDevice custom resource (CR) object for each node that provides a compatible PTP device.

One CR is created for each node, and shares the same name as the node. The .status.devices list provides information about the PTP devices on a node.

The following is an example of a NodePtpDevice CR created by the PTP Operator:

apiVersion: ptp.openshift.io/v1
kind: NodePtpDevice
