Python Cloud Functions: gcloud functions deploy Change Name Different From Source Code

Default

Usually we use this command

gcloud functions deploy test_hello_world --runtime python37 --trigger-http --project PROJECT_ID

To deploy a function named test_hello_world in the file main.py

def test_hello_world(request):    return 'Hello World'

Where you url for the function is

https://us-central1-PROJECT_ID.cloudfunctions.net/test_hello_world

Change Cloud Function Name

To change the cloud function name (different from source code function name)

gcloud functions deploy test --entry-point test_hello_world --runtime python37 --trigger-http --project travelopyz

Function name must contain only lower case Latin letters, digits and a hyphen (-). It must start with letter, must not end with a hyphen, and must be at most 63 characters long.

NOTE: It is not possible to group function name under subdirectory, such as /intents/test. An alternative would be via cloud functions url redirect via Cloud Functions Custom Domain With Firebase Hosting.

The generated url shall be

https://us-central1-PROJECT_ID.cloudfunctions.net/test

Change Source File

Sadly, the function must reside within the file named main.py, but you can change the directory name.

gcloud functions deploy test --entry-point test_hello_world --source production --runtime python37 --trigger-http --project travelopyz

--source=SOURCE Location of source code to deploy. Location of the source can be one of the following three options:

Source code in Google Cloud Storage (must be a .zip archive), Reference to source repository or, Local filesystem path (root directory of function source).

Create the file production/main.py.
