I have created an API Gateway and created an API config as well associated with it which lists a set of APIs. Now I want to add/modify a set of APIs. How do I update the same API config of this gateway?
I did it using gcloud CLI.
First create a new config using your updated open api spec file:
gcloud api-gateway api-configs create NEW_CONFIG_ID --api=MY_API --openapi-spec=openapi2-functions.yaml
Then update your api gateway with new config:
gcloud api-gateway gateways update MY-GATEWAY --api=MY-API --api-config=NEW_CONFIG_ID --location=YOUR_LOCATION
