Mapping Google App Engine service to Cloudflare-CodePudding

I'm having an Google App Engine service residing at https://service-dot-myproject.uc.r.appspot.com/

However I want it to be reachable via https://app.mydomain.com I have set up the DNS for mydomain.com on Cloudflare and added the custom domain mapping in app engine and set up a dispatch.yaml file

- url: "app.mydomain.com/*"
  service: service

Is there a way to somehow map

https://service-dot-myproject.uc.r.appspot.com -> https://app.mydomain.com ?

currently https://app.mydomain.com only resolves to defaultservice

CodePudding user response：

The following dispatch.yaml file resolved the issue

dispatch:
  - url: "app.mydomain.com/*"
    service: service

Also the file must be separatly deployed via:

gcloud app deploy dispatch.yaml
