I am trying to allow the Cloudbuild to access a private service behind an internal load balancer with an internal IP only. I followed this tutorial : https://cloud.google.com/build/docs/private-pools/use-in-private-network and created a builder pool with private network access. However, it is still not able to access my ILB through DNS name on the same private network.
Is there a good way to debug this or I did something wrong?
