1. Resources

• how to develop and debug your application locally with functions-framework-python.
• how to automate the deployment of Cloud Functions with Cloud Build on Google Cloud Platform.

Check the complete tutorial here.

2. Environment setup

2.0 Program Dependencies

• ffmpeg: brew install ffmpeg

2.1. Virtualenv

• Install Python 3.7+

• Create and activate an isolated Python environment

  virtualenv --python `which python3.7` venv
  source ./venv/bin/activate

• Install the dependencies

  pip install -r requirements-dev.txt
  pip install -r requirements.txt

3. Run and test the app locally

3.0 Place .env files

Create {project_root}/.env from {project_root}/deployment/.envexample.

3.1 Testing the pub/sub example

From inside root of the directory:

./scripts/run-local-pubsub.sh

From a different terminal window:

./scripts/test-local-pubsub.sh '{"call_id": "6fAoVoxkfCenkm2K6ejYGU", "partial_id": "bo6FTU5HbpsUmYn8TFofNq", "audio_partial_id": "a3HvzN9htW5H5j9i2X23mL"}'

test-local-pubsub.sh does the following behind the scenes:

• encodes the message passed as parameter in base64 format;
• reads the contents of ./scripts/payloads/test-local-payload.json and replaces its data property with the base64 encoded message;
• performs an HTTP post request to http://localhost:8080 (the default address the application runs when you execute ./scripts/run-local-pubsub.sh from the other terminal window), sending the modified JSON from the previous step in the payload.

On the terminal window where you ran ./scripts/run-local-pubsub.sh you should see some logs showing a message was received.

3.2 Testing the HTTP example

From inside root of the directory:

./scripts/run-local-http.sh

From a different terminal window:

./scripts/test-local-http.sh

test-local-http.sh performs a GET HTTP request to http://localhost:8080/?subject=FooBar and prints the response:

$ ./test-local-http.sh
Hello, FooBar!

4. Deployment

Run gcloud init.

1. Re-initialize your default configuration

2. Set the project to the one you created (there can be a time delay for a newly created project to appear in the list of your organization's projects.)

3. Confirm your email login

4. Do you want to configure a default Compute Region and Zone?

   • Hit Y and then enter
   • Set the zone to us-west4-a

5. Create an environment file ./deployment/<PROJECT_ID>.env with the given project id.

   • Escape any funny characters in your ./deployment/<PROJECT_ID>.env file that bash doesn't like with " " around the value after the = sign.
   • Lay down ./deployment/peerlogic-api-dev.env

6. Uncomment all lines in this file if running for the first time ./deployment/gcloud_deploy.bash and then run it from the root of this repository.
