Change servicegroup definition #17

Open raffis opened 5 years ago

raffis commented 5 years ago

Is your feature request related to a problem? Please describe

Currently we can not change the servicegroup definition. This is for instance required to set a custom zone.

Describe the solution you'd like

New config: kubernetes.namespaces.serviceGroupDefinition

Describe alternatives you've considered

There is not really a workaround if you need to put certain objects into other zones but a servicegroup is not available on all endpoints. Therefore changing the zone to another one is required, for example to a global zone.
