Getting Started with API Gateway: Challenge Lab
ARC109
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 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 will be made available to you.
This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials 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 recommended).
- Time to complete the lab---remember, once you start, you cannot pause a lab.
Challenge scenario
You are just starting your junior data analyst role. So far you have been helping teams create, manage and access backend data resources.
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 around exposing backend services as APIs. You have been asked to assist the team with their efforts using API Gateway, you receive a request to complete the following tasks:
- Develop the backend system using a Cloud Function
- Deploy and manage an API exposing the backend service with a fully managed gateway
- Subscribe to messages published on a Pub/Sub topic to react to events
Each task is described below, good luck!
Task 1. Create a Cloud Function
Create a new 2nd gen
Cloud Function called GCFunction
in the
Click Check my progress to verify the objective.
Task 2. Create an API Gateway
Once the Cloud Function is deployed, configure an API Gateway to proxy requests to the backend.
Use the following openapispec.yaml
file to reference the Cloud Function deployed in Task 1.
Deploy the API Gateway with the following properties:
Name | Value |
---|---|
Display Name | GCFunction API (wherever requested) |
API ID | gcfunction-api |
Select a service account | Compute Engine default service account |
Location | |
Config Name | gcfunction-api |
Click Check my progress to verify the objective.
Task 3. Create a Pub/Sub Topic and Publish Messages via API Backend
The development team would like the API backend to publish messages to a new Pub/Sub topic named demo-topic
.
Create a new Pub/Sub topic (demo-topic
) and push messages to it in the Cloud Function deployed earlier. Be sure to keep the option to create a default subscription enabled when creating the topic.
Use the snippet below to update the package.json
file and index.js
code in the Cloud Function deployed in Task 1.
package.json
index.js
Redeploy the Cloud Function once the index.js
and package.json
files have been updated.
Next, invoke the Cloud Function via API Gateway. If done correctly, a message will be published to the topic demo-topic
you've created in this task.
Click Check my progress to verify the objective.
Congratulations!
You have completed the Challenge! Congratulations!!
