add regional support to ComputeNetworkEndpointGroup

[flunderpero]

Describe the bug
I am trying to setup a load balancer for our Cloud Run services, but I am unable to create a ComputeNetworkEndpointGroup of type SERVERLESS.

I am able to specify SERVERLESS as networkEndpointType but location is expected to be a zone and a SERVERLESS endpoint group requires a region.

The error message is either:

  Warning  UpdateFailed  2s (x12 over 14s)  computenetworkendpointgroup-controller  Update call failed: error fetching live state: error reading underlying resource: summary: Error when reading or editing ComputeNetworkEndpointGroup "projects/tkt-dev-pero/zones/europe-west1/networkEndpointGroups/testneg": googleapi: Error 400: Invalid value for field 'zone': 'europe-west1'. Unknown zone., invalid, detail:

... when I try to use a region as location, or:

 NetworkEndpointGroup: googleapi: Error 400: Invalid value for field 'resource.networkEndpointType': 'SERVERLESS'. Network endpoint of type SERVERLESS is only allowed in regional scope., invalid, detail:

Besides that, I don't think there is a way to specify things like cloud-run-url-mask, so my attempt to create a proper endpoint group would be futile anyway. :-)

Hi @flunderpero, currently ConfigConnector only support zonal network endpoint group; I have added the request of regional network endpoint group into our backlog. We will plan and work on it and let you know when we have more information.

@xiaobaitusi We are also interested in this request. Has there been any update on adding regional support so we can support serverless NEG's through KCC?

Hello @travisrandolph-bestbuy, no updates yet on this request, but we'll let you know once we have any updates to share.

In the meantime, could you elaborate on whether this issue is a blocker, friction point, or nice-to-have for you?

[travisrandolph-bestbuy]

@jcanseco Sorry for not replying sooner. This is a friction point for us. Currently we have engineers who need to create the serverless NEG and attach it to our KCC created Load Balancer/URL Map.

Thanks for the response, @travisrandolph-bestbuy !

Closing; supported on KCC 1.87.0 now via https://cloud.google.com/config-connector/docs/reference/resource-docs/compute/computeregionnetworkendpointgroup
