cloud-build-cloud-functions-pipeline

1. Introduction

This is a simple project developed with the intent to show:

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.

git clone git@github.com:ivamluz/cloud-build-cloud-functions-pipeline.git
cd cloud-build-cloud-functions-pipeline

Create and activate an isolated Python environment

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

Install the dependencies

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

From inside the /scripts folder:

./run-local-pubsub.sh

From a different terminal window:

./test-local-pubsub.sh "my message"

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

encodes the message passed as parameter in base64 format;
reads the contents of 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 ./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 ./run-local-pubsub.sh you should see some logs showing a message was received.

From inside the /scripts folder:

./run-local-http.sh

From a different terminal window:

./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!

After everything is running, please make sure to keep reading the tutorial.
