Is it possible to configure two services on the same url in dispatch.yaml?

[Mina Demian]

Hi all,

Battling to get this to work. I have an app composed of two services - frontend in Angular, backend in Node.

dispatch:

  - url: "<frontend-app>-dot-apt-aleph-767.appspot.com/"
    service: <frontend-app>


  - url: "<frontend-app>-dot-apt-aleph-767.appspot.com/backend/"
    service: <backend-app>

This is the output from `gcloud app describe`:

dispatchRules:
- domain: <frontend-app>-dot-apt-aleph-767.appspot.com
  path: /
  service: <frontend-app>

- domain: <frontend-app>-dot-apt-aleph-767.appspot.com
  path: /backend/*
  service: <frontend-app>

When I navigate to the url for the frontend app, it works as expected. However, I get a 404 when I go to `<frontend-app>-dot-apt-aleph-767.appspot.com/backend`.

Is it even possible to have two services on the same domain in Google App Engine?

Thanks in advance

It is indeed possible to have multiple logical units that can share state using the datastore or memcache. You can use the dispatch.yaml to send incoming requests to a specific service (formerly known as modules) based on the path or hostname in the URL.The rules that you define in your dispatch file must use HTTP URL patterns that include the "." notation for separating sub-domains. URLs defined with the HTTPS "-dot-" notation are not supported. You may read more in-depth related information from the "Routing with a dispatch file" sub-chapter of the "How Requests are Routed" documentation page.

thank you for your response. i've configured my dispatch file as described in the documentation. however, i still get a 404 when I try to access my backend service from the frontend url.

any ideas?

How do you access the back-end service? Does your app.yaml define all your modules with handlers?
