Locality LB without Outlier Detection


I am running Istio in multi-primary, multi-network multicluster. It is my understanding from the documentation and from real-life tests that Locality LB won’t work until Outlier Detection is configured.

This effectively disables Locality LB unless Outlier Detection is defined.

Now the problem I have is that the only way to define the Outlier Detection is using Destination Rule for each single service within the mesh. It’s not possible to define it namespace-wide or mesh-wide.

I would like to be able to use Locality LB without the need to configure DestinationRule for every single service individually. Is this somehow possible?
