 To attach a maintenance profile to a node, the label ```cloud.sap/maintenance-profile=NAME``` has to be assigned the desired profile name.

+Multiple profiles can be assigned to a single node be setting ```cloud.sap/maintenance-profile=NAME1--NAME2--NAME3--...```.
 The operational state can then be left by the checks configured in all listed profiles.
 Any progress for the maintenance-required and in-maintenance states can only made using the profile, which initial triggered the whole maintenance workflow.
 That way specific maintenance workflows for different causes can be implemented.
