Deploying a React-based application on Google Cloud Platform

GCP offers a wide range of tools (like App Engine, Cloud Functions, Datastore, etc) that make it easier deploying serverless applications.

In this article, I'll talk about setting up a React application to be deployed on Google Cloud platform using App Engine and about storing my code on Google Cloud Source Repositories.

Create the React project

First, I create a new React project

npx create-react-app looney-tunes
cd looney-tunes
npm start

Create the new project on GCP

Now I setup the project on Google Cloud Platform

Install gcloud

I have to install gcloud CLI to interact with the project from my machine.

For Mac OS, download the .tar.gz file at https://cloud.google.com/sdk/docs/quickstart-macos and extract it. Then run ./google-cloud-sdk/install.sh.

Once reloaded the terminal, I run gcloud -v to check the installation

Google Cloud SDK 279.0.0
bq 2.0.53
core 2020.01.31
gsutil 4.47

Init gcloud

In the root folder of the React project I run gcloud init to initialize the project for GCP. Following the interactive CLI, I can setup the project

Setup the new remote for the repository and push

It's time to create my repository for this initial code. I search cloud repositories via the search bar

Click Add repository on the right-top corner. Then select Create new repository. Now I choose a name for my repository )project's name) and I select the GCP project

At this point, make sure Push code from a local Git repository is selected. I use the SSH authentication to push my code. From the root folder of the React project, I run

git remote add google ssh://rossanodan@gmail.com@source.developers.google.com:2022/p/looney-tunes-267812/r/looney-tunes
git push --all google

Error. Probably due to the missing API Key. I create a new API Key and I add it to my Cloud Source Repositories https://source.cloud.google.com/user/ssh_keys.

Once done, I run git push --all google once again to push my code.

Create the app.yaml file

To make Google Cloud Platform able to deploy the project, I add a new file in the root folder of the project: app.yaml

# [START app_yaml]
env: flex
runtime: nodejs
# [END app_yaml]

I save and push

Everything is ready! In the root folder of the project, I run gcloud app deploy. I select the region of the project (in my case, europe-west2)

The console prompts the following message

Services to deploy:

descriptor:      [/Users/rossanodan/Desktop/Development/looney-tunes/app.yaml]
source:          [/Users/rossanodan/Desktop/Development/looney-tunes]
target project:  [looney-tunes-267812]
target service:  [default]
target version:  [20200210t131032]
target url:      [https://looney-tunes-267812.appspot.com]

This is a preview of what is going to be deployed and published. I enter Y.


Once the project is deployed, I run gcloud app browse that opens https://looney-tunes-267812.appspot.com/.

Why is Cloud Source repo necessary? Is it possible to deploy without it?
