Triggering a Cloud Function with an HTTP request is a core service ability and one you should be familiar with, especially using the latest version of Cloud Functions, 2nd gen. In this hands-on lab, you’ll retrieve the working files you’ll need from a GitHub repo and use them to create an HTTP 2nd gen Cloud Function. Once deployed, you’ll test the function in various ways to ensure all aspects are working properly.
Successfully complete this lab by achieving the following learning objectives:
- Enable APIs
Enable the four necessary APIs: Cloud Functions, Cloud Run, Cloud Build, and Artifact Registry.
- Retrieve Files from the Repo and Configure
Use the Cloud Shell to clone the directory referenced below. Once retrieved, use the Cloud Shell Editor to open the
main.pyfile in the
http-2nd-genfolder, and copy it’s contents.
- Create the Function
Create and deploy a Cloud Function with the following properties and the code from the source files:
- Environment: 2nd gen
- Function name: http-trigger
- Region: us-east1
- Maximum number of instances: 2
- Runtime: Python 3.10
- Use the inline editor for the source code
- Entry point: greetings_http
- Test the Function
Test the function by reviewing the results of the triggered URL, first at its default stage and then with a URL query passing the
