I had a similar issue setting up integration tests on cloud build. I was trying to run integration tests from another builder (go-builder) against my other containers (started through docker-compose community built containers).

Without specifying any networks on docker-compose.yaml, all containers are started on the default network (https://docs.docker.com/compose/networking/). On cloud build, it creates a new network named cloudbuild_default and places all my containers there. By forcing all containers to join cloudbuild network through my docker-compose.yaml file, I was able to establish communications and run my tests against them.

#docker-compose.yaml

networks:
  default:
    external:
      name: cloudbuild

This might be an alternate configuration for you. Hope it helps
