John:
QQ I am trying to remove a label from a control plane
k label node control-plane disk=ssd
k label node control-plane disk=ssd-
error: invalid label value: “disk=ssd-”: a valid label must be an empty string or consist of alphanumeric characters, ‘-’, ‘’ or ‘.’, and must start and end with an alphanumeric character (e.g. ‘MyValue’, or ‘my_value’, or ‘12345’, regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9])?’)
any ideas as to what I am doing wrong
