I have an app that uses the following command to deploy a static app generated by create-react-app:
gcloud app deploy --project MY_PROJECT -v dev
After that, my app is available on myproject.appstop.com.
But I don't figure out how to deploy this app using a diff URL for each environment. Like.: dev.myproject.appspot.com, stg.myproject.com and so on.
If you know or have other ideas about how to solve this please share your thoughts.
