I have tree Cloud Run testing services: hello-default, hello-blue, hello-green.
I've created an HTTPs Loadbalancer having those 3 services as individual backend services as Network Endpoint Groups. That means the Loadbalancer has 3 backend services, one for each mentioned service.
I want to achieve this basic routing:
My goal is to send "hello.site.com/blue/" to be sent to hello-blue service and "hello.site.com/green/" to be sent to hello-green
But when I save the Loadbalancer the routing table changes to this:
And when I go to "hello.site.com/blue/" and "hello.site.com/green/" they always hit the hello-default backend, which gives 404 because it doesn't have those paths.
Then, I edited my Loadbalancer to set the routing as the following with no success:
It seems the routing is being completely ignored. What have I missed? Why does GCP adds those extra routing rules "/*"
As @Joachim Isaksson pointed out, it turns out I missed the meaning of the "Hosts" field on the routing setting. Using the right host value fixed the issue.
