We are currently using terraform to provision our infrastructure on GCP. One of the resources we are managing with terraform is our Google API Gateway. We have created a “google_api_gateway_api” resource and have paired it with a “google_api_gateway_api_config” and “google_api_gateway_gateway”. The problem we are facing is that every time the configuration is updated, the existing configuration and gateway are destroyed and re-created, resulting in downtime for our gateway.
Using the Google Cloud UI, there is a way to add a new configuration without destroying the existing one and taking down the gateway. How would we accomplish this using terraform? We have tried using the lifecycle { create_before_destroy = true } block within “google_api_gateway_api_config” , but this results in a 409 resource already exists error.
