Is there a way to perform a
kubectl run --image=busybox mydeployment sleep 100but by selecting nodes e.g. that were created after a specific timestamp for example?
In order to select the node, you can edit the json of the created resource using the --overrides flag.
For instance, this creates a pod on the node name:
kubectl run nginx --generator=run-pod/v1 --image=nginx --overrides='{ "spec": { "nodeName": "name" } }'
