Function deployment and testing in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the first step to deploy a function on Google Cloud Platform?

The first step is to write your function code and prepare a deployment package or source code in a supported language.

beginner

Which Google Cloud service is used to deploy serverless functions?

Google Cloud Functions is the service used to deploy serverless functions that run in response to events.

intermediate

What command is used to deploy a function using the gcloud CLI?

Use the command: gcloud functions deploy FUNCTION_NAME --runtime RUNTIME --trigger-http to deploy a function with an HTTP trigger.

beginner

How can you test a deployed Google Cloud Function?

You can test it by sending an HTTP request if it has an HTTP trigger, or by triggering the event it listens to, then checking logs or output.

beginner

Why is it important to check logs after deploying a function?

Logs help you see if the function ran correctly or if there were errors, making it easier to fix problems.

Which command deploys a Google Cloud Function with an HTTP trigger?

A gcloud function create myFunc --trigger-http

B gcloud deploy function myFunc --runtime python39

C gcloud functions start myFunc --http

D gcloud functions deploy myFunc --runtime python39 --trigger-http

The correct command is 'gcloud functions deploy FUNCTION_NAME --runtime RUNTIME --trigger-http'.

What is a common way to test a function with an HTTP trigger?

A Send an HTTP request to the function's URL

B Restart the Google Cloud project

C Upload a file to Cloud Storage

D Run a SQL query

Functions with HTTP triggers respond to HTTP requests, so sending a request tests them.

Where can you find detailed error messages if a function fails?

A In the Cloud Storage bucket

B In the billing section

C In the function's logs on Google Cloud Console

D In the Compute Engine dashboard

Logs provide detailed information about function execution and errors.

Which runtime is NOT supported by Google Cloud Functions?

A Python 3.9

B Ruby 3.0

C Java 17

D Node.js 16

Ruby is not currently supported as a runtime for Google Cloud Functions.

What does the '--trigger-http' flag do during deployment?

A Makes the function respond to HTTP requests

B Triggers the function on file upload

C Runs the function on a schedule

D Deploys the function without a trigger

The '--trigger-http' flag sets the function to respond to HTTP requests.

Explain the steps to deploy a Google Cloud Function and how to test it after deployment.

Think about writing code, deploying with gcloud, then testing and checking logs.

Describe why logs are important in function deployment and testing.

Logs are like a diary for your function's actions.
