Deploying streaming functions to Cloud Run

This sample shows how to deploy streaming functions to Cloud Run with the Functions Framework. The main.py file contains examples for both synchronous and asynchronous streaming.

Dependencies

Install the dependencies for this example:

pip install -r requirements.txt

Running locally

Synchronous Streaming

To run the synchronous streaming function locally:

functions-framework --target=hello_stream

Then, send a request to it from another terminal:

curl localhost:8080

Asynchronous Streaming

To run the asynchronous streaming function locally:

functions-framework --target=hello_stream_async

Then, send a request to it from another terminal:

curl localhost:8080

Deploying to Cloud Run

You can deploy these functions to Cloud Run using the gcloud CLI.

Synchronous Streaming

gcloud run deploy streaming-function \
    --source . \
    --function hello_stream \
    --base-image python312 \
    --region <YOUR_REGION>

Asynchronous Streaming

gcloud run deploy streaming-async-function \
    --source . \
    --function hello_stream_async \
    --base-image python312 \
    --region <YOUR_REGION>
