[GCP] [Python] Deploy API serverless with Google Cloud Functions!

Hello. This is Satchie. Since it is neat, I misunderstood the day of the week to post last week. Excuse me. The day before, @ Rimo1129 (junior) wrote Make something like a job hunting portfolio on AWS ~ !!!!! As a job hunting chan, it is too good to write an Advent calendar. Right. I don't understand AWS at all, so please let me know. I don't know AWS, so I would like to play with Google Cloud Functions provided by Google.

What is Google Cloud Functions?

Cloud Functions is a serverless execution environment that you can use to create and connect to cloud services. Cloud Functions allows you to create simple, single-purpose functions related to events that occur in your cloud infrastructure or services. The function is triggered when the event of interest occurs.

That's right. It's like AWS lambda. This time, by specifying HTTP as a trigger, we will deploy the API serverlessly so that it can be hit.


In Previous article, we collected information on restaurants around the company using the API of Gurunavi. This time I'm going to deploy a function that takes a keyword and a search method (and or or) as parameters and returns a list of store information that contains the keyword in the word of mouth. Since the data was small, I will prepare it in the following json without putting it in the database.

This time we will create a function on the GCP console. Of course, you can also deploy locally with gcloud commands. We will create a function. Specify HTTP for the trigger here. When exposing authentication as an API, allow unauthenticated calls. スクリーンショット 2020-12-19 6.04.39.png

Next, set the runtime to Python, write the required packages in requirements.txt, and change the entry point to the name of the function you want to execute. Also, when using Cloud Function for the first time, it is necessary to enable Cloud Build from the point of "Enable API". After that, write a function and add any necessary files. (This time shop_data.json is added)

A green checkmark will appear when the deployment is complete. スクリーンショット 2020-12-19 7.14.40.png

It's back!

At the end

In this way, the API was easily created just by registering the function from the console. There are various triggers other than HTTP, so it seems fun to master the GCP service.
