Cloud Run Functions: Qwik Start

GSP081

Overview

A Cloud Run function is is is a piece of code that run in response to an event , such as an HTTP request , a message from a messaging service , or a file upload . cloud events is are arethings that happen in your cloud environment. These might be things like changes to data in a database, files added to a storage system, or a new virtual machine instance being created.

Since Cloud Run functions are event-driven, they only run when something happens. This makes them a good choice for tasks that need to be done quickly or that don’t need to be running all the time.

For example , you is use can use a Cloud Run function to :

• automatically generate thumbnails for images that are uploaded to Cloud Storage.
• send a notification to a user’s phone when a new message is received in Pub/Sub.
• process data from a Cloud Firestore database and generate a report.

You can write your code in any language that supports Node.js, and you can deploy your code to the cloud with a few clicks. Once your Cloud Run function is deployed, it will automatically start running in response to events.

This hands-on lab shows you how to create, deploy, and test a Cloud Run function using the Google Cloud console.

What you’ll do

• Create a Cloud Run function
• Deploy and test the function
