	// SeedLabel determines if a member is a seed or not.
	SeedLabel = "scylla/seed"

	// DecommissionLabel expresses the intent to decommission
	// the specific member. The presence of the label expresses
	// the intent to decommission. If the value is true, it means
	// the member has finished decommissioning.
	// Values: {true, false}
	DecommissionLabel = "scylla/decommissioned"

	// ReplaceLabel express the intent to replace pod under the specific member.
	ReplaceLabel = "scylla/replace"

	// NodeMaintenanceLabel means that node is under maintenance.
	// Readiness check will always fail when this label is added to member service.
	NodeMaintenanceLabel = "scylla/node-maintenance"

	LabelValueTrue  = "true"
	LabelValueFalse = "false"
)

These labels are only used on the ClusterIP services acting as each member's identity (static ip). Each of these labels is a record of intent to do something. The controller sets these labels and each member watches for them and takes the appropriate actions.

See the sidecar design doc for more details.
