A Cloud Run function is a piece of code that runs in response to an event, such as an HTTP request, a message from a messaging service, or a file upload. Cloud events are things 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 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.

Setup and requirements
Before you click the Start Lab button
Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources are made available to you.
This hands-on lab lets you do the lab activities in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials you use to sign in and access Google Cloud for the duration of the lab.
To complete this lab, you need:
Access to a standard internet browser (Chrome browser recommended).
Note: Use an Incognito (recommended) or private browser window to run this lab. This prevents conflicts between your personal account and the student account, which may cause extra charges incurred to your personal account.
Time to complete the lab—remember, once you start, you cannot pause a lab.
Note: Use only the student account for this lab. If you use a different Google Cloud account, you may incur charges to that account.
How to start your lab and sign in to the Google Cloud console
Click the Start Lab button. If you need to pay for the lab, a dialog opens for you to select your payment method.
On the left is the Lab Details pane with the following:
The Open Google Cloud console button
Time remaining
The temporary credentials that you must use for this lab
Other information, if needed, to step through this lab
Click Open Google Cloud console (or right-click and select Open Link in Incognito Window if you are running the Chrome browser).
The lab spins up resources, and then opens another tab that shows the Sign in page.
Tip: Arrange the tabs in separate windows, side-by-side.
Note: If you see the Choose an account dialog, click Use Another Account.
If necessary, copy the Username below and paste it into the Sign in dialog.
{{{user_0.username | "Username"}}}
You can also find the Username in the Lab Details pane.
Click Next.
Copy the Password below and paste it into the Welcome dialog.
{{{user_0.password | "Password"}}}
You can also find the Password in the Lab Details pane.
Click Next.
Important: You must use the credentials the lab provides you. Do not use your Google Cloud account credentials.
Note: Using your own Google Cloud account for this lab may incur extra charges.
Click through the subsequent pages:
Accept the terms and conditions.
Do not add recovery options or two-factor authentication (because this is a temporary account).
Do not sign up for free trials.
After a few moments, the Google Cloud console opens in this tab.
Note: To access Google Cloud products and services, click the Navigation menu or type the service or product name in the Search field.
Task 1. Create a function
In this step, you're going to create a Cloud Run function using the console.
In the console, on the Navigation menu () click Cloud Run.
Click WRITE A FUNCTION.
In the function dialog, enter the following values:
Field
Value
Service name
gcfunction
Region
Authentication
Allow unauthenticated invocations
Memory allocated (In Container(s), Volumes and Security Settings)
Keep default
Execution environment (In Container(s), Volumes and Security Settings)
Second generation
Revision scaling (In Container(s), Volumes and Security Settings)
Set the Maximum number of instance to 5, and then click Create
Note: A helpful popup may appear to validate the required APIs are enabled in the project. Click the ENABLE button when requested.
You deploy the function in the next section.
Task 2. Deploy the function
Still in the Create function dialog, in Source code for Inline editor use the default helloHttp function implementation already provided for index.js.
Click SAVE and REDEPLOY to deploy the function.
Note: While the function is being deployed, the icon next to it is a small spinner. When it's deployed, the spinner is a green check mark.
Test completed task
Click Check my progress to verify your performed task. If you have completed the task successfully you will be granted an assessment score.
Deploy the function.
Task 3. Test the function
Test the deployed function.
On the function details dashboard, to test the function click TEST.
In the Triggering event field, enter the following text between the brackets {} .
"message":"Hello World!"
Copy the CLI test command and run it in the cloud shell.
You will see the "Hello World!" message as the output.
Task 4. View logs
View logs from the service details page.
On the Service Details Overview page click Logs tab
Example of the log history that displays in Results:
Your application is deployed, tested, and you can view the logs.
Test the function
Task 5. Test your understanding
Below are multiple-choice questions to reinforce your understanding of this lab's concepts. Answer them to the best of your abilities.
Congratulations!
You used the Google Cloud console to create, deploy, and test a Cloud Run function.
