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 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.

Challenge scenario

You are a junior cloud engineer tasked with helping teams create and manage Google Cloud resources. As part of your duties, you have been tasked with using AppSheet and App Scripts to create chat apps, which are web applications or services that run in Google Chat. Creating a chat app with AppSheet or App Scripts lets you interact directly with the app in Google Chat rather than opening it in a separate window.

Your first challenge is to use AppSheet to create a no-code application to report and manage automated teller machine (ATM) issues. You start by copying a simple maintenance app to use it as a template for adding functionality. You then add a chat component, so you can interact with the app directly in Google Chat.

Your second challenge is to use an App Scripts template to create a chat bot that is more customizable using event handlers.

You are expected to have the skills and knowledge to complete the tasks that follow.

Your challenge

In this lab, you are asked to create two applications that run in Google chat:

1. No-code chat app using AppSheet

2. App Scripts app with event handlers

You need to:

• Create the apps based on templates.

• Customize the apps (such as adding some automation).

• Publish the bots.

Task 1. Create and customize an AppSheet app

For this task, copy and customize an existing ATM Maintenance app, which technicians use to perform ATM maintenance. Be sure to deploy your app after you have customized it.

Create the app

1. Open the ATM Maintenance app in AppSheet.

2. Set the following values, leaving all others at their defaults:

   | Property | Value (type value or select option as specified) | | --- | --- | | App name | ATM Maintenance Tracker |

Customize the first message

• Set the following values, leaving all others at their defaults:

  | Property | Value (type value or select option as specified) | | --- | --- | | message text | Welcome to the ATM Maintenance Tracker app. What would you like to do today? |

Create a slash command

• Set the following values, leaving all others at their defaults:

  | Property | Value (type value or select option as specified) | | --- | --- | | App View | Issues Reported By Me | | Name | /myissues | | Description | Lists tickets that include your email address |

  } else {
    message = "Thank you for adding me to " +
        (event.space.displayName ? event.space.displayName : "this chat");
  }

  if (event.message) {
    message = message + " and you said: \"" + event.message.text + "\"";
  }
  console.log('Helper Bot added in ', event.space.name);
  return { "text": message };
}

/**
 * Responds to a REMOVED_FROM_SPACE event in Google Chat.
 *
 * @param {Object} event the event object from Google Chat
 */
function onRemoveFromSpace(event) {
  console.info("Bot removed from ",
      (event.space.name ? event.space.name : "this chat"));
