Setup Yoda Executor Using Google Cloud Function

Google Cloud Platform provides a function executor service called "Google Cloud Function". Yoda's executor runtime can be deployed on Google Cloud Function by following this instruction.

In your Google cloud platform account, go to Cloud Functions Page and click Create function.

Step 1: Setup HTTP Triggers

Follow the following steps:

• Choose your Function name and Region
• Set Trigger type to HTTP
• For Authentication, choose Allow unauthenticated invocations

Step 2: Configure Runtime and Environment Variables

Scroll further to VARIABLES, NETWORKING, AND ADVANCED SETTINGS in ADVANCED section. We recommend using 1 GiB RAM and 12 seconds timeout.

Then, create new environment variables for the runtime below.

Key	Value
MAX_EXECUTABLE	8192
MAX_DATA_SIZE	4096

Click next to go to the code setting.

Step 3: Upload Runtime Source Code

1. Choose Runtime to Python 3.9
2. Set Entry point to execute
3. Choose Source code to ZIP Upload
4. You need to upload the runtime zip.
5. For Stage bucket, if you don't have an existing stage bucket, create a new one.

Step 4: Deploy the Function

Click Deploy at the bottom of the current page. If the deployment is successful, You will see the correct symbol.

Step 5: Test the function

Let's get Trigger URL by clicking the function name and go to Trigger tab.

You can test the endpoint using curl with the following command

curl --location --request POST '<your_trigger_url>' \
--header 'Content-Type: application/json' \
--data-raw '{
