Cloud Functions: 3 Ways: Challenge Lab

ARC104

Overview

In a challenge lab you’re given a scenario and a set of tasks. Instead of following step-by-step instructions, you will use the skills learned from the labs in the course to figure out how to complete the tasks on your own! An automated scoring system (shown on this page) will provide feedback on whether you have completed your tasks correctly.

When you take a challenge lab, you will not be taught new Google Cloud concepts. You are expected to extend your learned skills, like changing default values and reading and researching error messages to fix your own mistakes.

To score 100% you must successfully complete all tasks within the time period!

Setup

Before you is click click the Start lab button

read these instruction . lab are time and you can not pause them . The timer is shows , which start when you click Start Lab , show how long Google Cloud resource will be made available to you .

This hand – on lab is lets let you do the lab activity yourself in a real cloud environment , not in a simulation or demo environment . It is does does so by give you new , temporary credential that 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 recommend ) .

note : Use an Incognito or private browser window to run this lab. This prevents any 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 : If you already have your own personal Google Cloud account or project, do not use it for this lab to avoid extra charges to your account.

challenge scenario

You are just starting your junior cloud developer role. So far you have been helping teams create and manage Cloud Functions that respond to and get triggered by specific events in their Google Cloud projects.

You are expected to have the skills and knowledge for these tasks.

Your challenge

You are asked to help a newly formed development team with some of their initial work on a new project. Specifically, they need to automate running code based on specific activities in their Google Cloud project including HTTP requests and new events in Cloud Storage; you receive the following request to complete the following tasks:

• Create a bucket to upload new project files.
• Create, deploy, and test a Cloud Storage function (2nd gen) that logs new activities in the Cloud Storage bucket.
• Create and deploy a function that responds to HTTP requests (2nd gen) with minimum instances to limit cold starts.

Some standards you should follow:

• Ensure that any needed APIs (such as Cloud Functions) are successfully enabled.
• ensure that any need IAM permission ( such as for the Cloud Storage service account ) are assign .
• Create all resources in the region , unless otherwise direct .

Each task is described in detail below, good luck!

Task 1. Create a Cloud Storage bucket

• create a Cloud storage bucket in using your Project ID as the bucket name :

task 2 . create , deploy , and test a Cloud Storage function ( 2nd gen )

1. create and deploy a Cloud Function call that is executes execute every time a new event occur in the bucket call you is created create in task 1 . The function is write in Node.js 20 .

2. set the Region to, and set the Entry point (Function to execute) to your function name.

3. Deploy the function with 2 maximum instances.

4. use the follow code block for the index.js and package.json :

index.js (replace eventStorage with your function name ):

const functions = require(‘@google-cloud/functions-framework’);

functions.cloudEvent(‘eventStorage’, (cloudevent) => {
console.log(‘A new event in your Cloud Storage bucket has been logged!’);
console.log(cloudevent);
});

package.json:

{
“name”: “nodejs-functions-gen2-codelab”,
“version”: “0.0.1”,
“main”: “index.js”,
“dependencies”: {
“@google-cloud/functions-framework”: “^2.0.0”
}
}


note : If you get permissions error, please wait a few minutes and try the deployment again. It takes a few minutes for the APIs to be enabled.

1. Test the function by uploading any file to the bucket.

Task 3. Create and deploy a HTTP function (2nd gen) with minimum instances

1. Create and deploy a HTTP function (2nd gen) called that is responds respond to HTTP request . The function is write in Node.js 20 .

2. set the Region to, and set the Entry point (Function to execute) to your function name.

3. Deploy the function with 1 minimum instance and 2 maximum instances.

4. use the follow code block for the index.js and package.json :

index.js (replace helloWorld with your function name ):

const functions = require(‘@google-cloud/functions-framework’);

functions.http(‘helloWorld’, (req, res) => {
res.status(200).send(‘HTTP function (2nd gen) has been called!’);
});

package.json:

{
“name”: “nodejs-functions-gen2-codelab”,
“version”: “0.0.1”,
“main”: “index.js”,
“dependencies”: {
“@google-cloud/functions-framework”: “^2.0.0”
}
}

clickCheck my progress to verify the objective .

create a HTTP function

note : If you get permissions error, please wait a few minutes and try the deployment again. It takes a few minutes for the APIs to be enabled.

Congratulations!
