If you are not familiar with the oc command, refer to OpenShift - Getting Started with the oc command.

The oc get events command can be used the list the recent events in your currently selected project / namespace.

oc get events

If there are events, something like this should be displayed.

LAST SEEN   FIRST SEEN   COUNT     NAME                                                             KIND      SUBOBJECT                        TYPE      REASON      SOURCE              MESSAGE

The oc delete events --all command can be used to clear all of the events in your currently selected project / namespace. All of the events that were deleted should be listed.

~]# oc delete events --all
event "my-hello-world-image-1-deploy.17123431f4afdb14" deleted
event "my-hello-world-image-1-deploy.17123432854132fd" deleted
event "my-hello-world-image-1-deploy.171234328d9dfd8d" deleted
event "my-hello-world-image-1-deploy.1712343297a3b0a8" deleted
event "my-hello-world-image-1-deploy.171234329908b8ec" deleted
event "my-hello-world-image-1-deploy.1712347f3fcdb40a" deleted
event "my-hello-world-image-1-xtmsv.17123432a13ee534" deleted
event "my-hello-world-image-1-xtmsv.17123433135b84b4" deleted
event "my-hello-world-image-1-xtmsv.171234331e689808" deleted
event "my-hello-world-image-1-xtmsv.1712344f12ee053a" deleted
event "my-hello-world-image-1-xtmsv.1712344f12ee3d51" deleted
event "my-hello-world-image-1-xtmsv.1712344f25aa7c46" deleted
event "my-hello-world-image-1-xtmsv.1712344f25aa9f27" deleted
event "my-hello-world-image-1.17123432a09ae02f" deleted
event "my-hello-world-image.17123431f18682c2" deleted

Now the oc get events command should return the following.

~]# oc get events
