This example demonstrates how to deploy multiple python services to App Engine flexible environment

Open a terminal and start the first service:

$ cd gateway-service
$ # follow https://cloud.google.com/python/docs/setup to set up a Python
development environment
$ pip install -r requirements.txt
$ python main.py

In a separate terminal, start the second service:

$ cd static-service
$ # follow https://cloud.google.com/python/docs/setup to set up a Python
$ pip install -r requirements.txt
$ python main.py

Each directory contains an app.yaml file. These files all describe a separate App Engine service within the same project.

For the gateway:

Gateway service

This is the default service. There must be one (and not more). The deployed url will be https://<your project id>.appspot.com

For the static file server:

Static file service

The deployed url will be https://<service name>-dot-<your project id>.appspot.com

To deploy a service cd into its directory and run:

$ gcloud app deploy app.yaml

and enter Y when prompted. Or to skip the check add -q.

To deploy multiple services simultaneously just add the path to each app.yaml file as an argument to gcloud app deploy :

$ gcloud app deploy gateway-service/app.yaml static-service/app.yaml
