feat: Allow to set registry server rest/grpc mode in operator#5364

ntkathole

What this PR does / why we need it:

This PR adds capability in feast-operator to allow user to deploy registry serving in REST or gRPC or both mode.

New configuration fields:

GRPC: Toggle gRPC server (--grpc/--no-grpc)
RestAPI: Toggle REST API server (--rest-api)
When REST API is enabled:
- Creates separate service with -rest suffix
- Configures dedicated REST API port
- Supports both HTTP/HTTPS
Service hostnames:
- Separate hostname for REST API endpoints
- Format: {service-name}-rest.{namespace}.svc.cluster.local:{port}
Maintains backward compatibility with existing gRPC deployments.

Setting restAPI: true will deploy registry with :
feast serve_registry --rest-api

spec:
  feastProject: example
  services:
    registry:
      local:
        server:
          restAPI: true
          grpc: true

Additionally, also fixed the issue in f231f0d with rest port not used when grpc is disabled and only rest-api is enabled. Earlier it was using default grpc port instead of default rest port.

tchughesiv

when rest is enabled for registry, does the default port change?

ntkathole

when rest is enabled for registry, does the default port change?

nope, same default port is used, unless changed explicitly by user.

tchughesiv

@ntkathole please add unit tests to check that the rest option is being properly handled in the resulting Deployment object... and any other tests related to this PR that you think would be valuable. Also, please update the description to match any design changes that have occurred.

tchughesiv

Based on the failing e2e test around remote registry use, it's clear that using rest api mode will break registry's ability to be used as a "remote" provider type. this adds additional complexity that will need to be handled/checked ... likely in this method -

           			apimeta.IsStatusConditionTrue(remoteFeast.Handler.FeatureStore.Status.Conditions, feastdevv1alpha1.RegistryReadyType) && 
        
           			len(remoteFeast.Handler.FeatureStore.Status.ServiceHostnames.Registry) > 0 { 
        
           			feast.Handler.FeatureStore.Status.ServiceHostnames.Registry = remoteFeast.Handler.FeatureStore.Status.ServiceHostnames.Registry 
        
           		} else { 
        
           			return errors.New("Remote feast registry of referenced FeatureStore '" + remoteFeast.Handler.FeatureStore.Name + "' is not ready") 
        
           		} 
        
           	} 
        
           	return nil 
        
           }

If restAPI is true in the remote registry CR being used, we'd want to notify the user in the Status that remote provider registry capabilities cannot be used.

It would probably be good idea to check this in with a unit test as well. Maybe ensure whatever status message you set is being handled correctly.

There are existing remote registry tests in infra/feast-operator/internal/controller/featurestore_controller_test.go for reference. Might be a good place to add more.

looking good, but we still need checks added as mentioned in this prior review comment -

Can you provide an example here, I didn't get how user can set restAPI true in the remote registry ? I think we have only added restAPI flag option for local registry server configs.

A user can reference a registry in another FeatureStore CR and use it as a remote registry -

feast/infra/feast-operator/test/testdata/feast_integration_test_crs/v1alpha1_remote_registry_featurestore.yaml

Lines 11 to 15 in 6c92447

                 name: simple-feast-setup 
        
                 namespace: default

We already have tests in place (both e2e & unit) around this feature. Given the restAPI breaks this functionality, you'll need to add an additional check in -

           	}) 
        
           }

the issue is that you're breaking the setting of ports for other service types (online, offline, etc)...
something like this should do the trick -

	if feastType == RegistryFeastType {
		if feast.isRegistryGrpcEnabled() {
			container.Ports = append(container.Ports, corev1.ContainerPort{
			    	Name:          name,
			    	ContainerPort: getTargetPort(feastType, tls),
			    	Protocol:      corev1.ProtocolTCP,
			})
		    }
		if feast.isRegistryRestEnabled() {
		    	container.Ports = append(container.Ports, corev1.ContainerPort{
		    		Name:          name + "-rest",
		    		ContainerPort: getTargetRestPort(feastType, tls),
		    		Protocol:      corev1.ProtocolTCP,
		    	})
		    }
        } else {
            container.Ports = append(container.Ports, corev1.ContainerPort{
		    	Name:          name,
		    	ContainerPort: getTargetPort(feastType, tls),
		    	Protocol:      corev1.ProtocolTCP,
            })
        }

the above would be done in addition to the other suggestions i've made around the isRegistryRestEnabled & isRegistryGrpcEnabled method changes

looking good! one more change requested.

we also need unit tests for changes made around the rest & grpc container ports, services, probeHandlers, etc.
