TB Edge won't connect to TB deployed in GKE

[rbarberop]

I've deployed TB in GKE and TB Edge following the instructions on the official website, but Edge won't connect:

2022-11-18 16:53:28,542 [main] INFO o.t.edge.rpc.EdgeGrpcClient - [287b07ab-d594-49c1-04e1-1f8b4da7dc5b] Sending a connect request to the TB!

I suspect that it has to be with the deployment config files, since tb-node container defines port 7070, but then there is no service listening on that port. only 8080.

Am I missing anything?
