Google Cloud Functions Course

Starting a project

To start a new project in Google Cloud, we can go to the Firebase Console or create it from Google Cloud Platform Console.

Creating a virtual environment

First we have to install python3-venv with:

sudo apt install python3-venv

Then, we create the virtual environment:

python3 -m venv venv

To activate the virtual environment:

source venv/bin/activate

Then, we can add dependencies (packages) by putting them in a requirements.txt file and we then install them with:

pip install -r requirements.txt

Deploying our functions

First, we have to set our project ID with the following command:

gcloud config set project [YOUR_PROJECT_ID]

Then we deploy our function with this command:

gcloud functions deploy [FUNCTION_NAME] --runtime python37 --trigger-http

Deploying cloud functions with environment variables and other dependencies

We have to create a .env.yaml file and a requirements.txt file in the same directory of our main.py and then run the following command:

gcloud functions deploy [FUNCTION_NAME] --env-vars-file .env.yaml --runtime python37 --trigger-http

Schedule Cloud Functions

We execute the following commands:

gcloud components install beta
gcloud components update
gcloud pubsub topics create [TOPIC_NAME]
gcloud pubsub subscriptions create cron-sub --topic [TOPIC_NAME]

Deleting a Cloud Function

To delete a Cloud Function run the following command:

gcloud functions delete [FUNCTION_NAME]
