Should a node be removed at least its prometheus/monitoring entry in the mine should be removed. Given a node pi-k8s-01 run the following command to remove all mine entries.

salt-run mine.update 'pi-k8s-01' clear=True

The previous command only works while the minion is still connected to the master. If the minion is already removed you can execute this command.

salt-run cache.clear_all pi-k8s-01
