The error is clear: GCP resource names don't allow underscores (_). The problematic names contain underscores like qa_worker which violates GCP's naming regex ^(?:a-z?)$.

To be fair, the best course of action here is to rename the services in your Compose file. Different clouds have different rules and for us to silently rename your service(s) to match the rules of the cloud is hard, and potentially confusing since you won't easily find the service in the Cloud dashboard if the names don't match.

_ is common enough so we should probably handle that? We already handle ..
