### Assign Services to Cluster Nodes
By default all services are distributed among the cluster nodes with the `Checker`
feature enabled.
If you require specific services to be only executed by one or more checker nodes
within the cluster, you must define `authorities` as additional service object
attribute. Required Endpoints must be defined as array.

services["dmz-oracledb"] = {
templates = [ "generic-service" ],
