Lab Details:

  1. This lab walks you through GCP Cloud Function and Cloud Pub-Sub Services.

  2. Make sure, you have completed the previous labs about GCP Cloud Function and Cloud Pub-Sub because here we will not go into detail about theory but we will connect these two services. If you have not completed the previous lab, we recommend you complete the previous lab first. 

  3. In this lab, we will create a Cloud Pub-Sub Topic and Cloud Functions.

  4. Then we will trigger the Cloud Pub-Sub from Cloud Functions.

  5. Finally, we will send a message from Cloud Pub-Sub and we will verify the message from Cloud Functions.

  6. Duration: 45 minutes

Lab Overview:

In this lab, we will create a Cloud function and trigger a Cloud Pub-Sub to display a message by using a python code. The trigger is the response to an event with the function call. Then, once we send the message in the Pub-sub we will be verifying from the Cloud Function logs.

  1. Log into GCP Console

  2. Create a Cloud Pub-Sub Topic

  3. Create a Cloud Functions

  4. Trigger a Cloud Pub-Sub in the Cloud Functions
