GDG-SILIGURI-X-GCCD-Extended-Event: Deploying a Python Web App Using Docker on Google Cloud Run

Welcome to our tutorial where you'll learn how to deploy a simple Python web application using Docker and Google Cloud Run. We'll utilize Terraform for infrastructure orchestration.

Prerequisites

Ensure you have the following installed:

1. Git (version 2.39 or higher)
2. Docker (version 27.0 or higher)
3. gcloud CLI
4. Terraform (version 1.6 or higher)

For manual provisioning via the console, please see the references section at the end of this document.

Tutorial Steps

Step 1: Clone the Repository

Clone the repository to get the required files:

git clone [email protected]:Google-Developer-Groups-Siliguri/GDG-SILIGURI-X-GCCD-Extended-Event.git

Step 2: Setup Google Cloud Console

Create a Google Cloud account and login to the console. Once logged in, create a new project.

Step 3: Update Project ID

Update the project ID in the Makefile and terraform/terraform.tfvars files. Replace the placeholder with your own project ID.

Step 4: Build and Push the Docker Image

Build and push the Docker image to your Google Container Registry:

make docker-push

You will be redirected to your browser to authenticate. Complete the authentication process, and this will build and push your Docker image to GCR.

Step 5: Deploy Your Application

Navigate to the terraform directory and run the following command:

terraform apply

You will be prompted with the planned changes. Type yes and press Enter to continue. After some time, you will receive a successful response along with the public URL of your application as output.

In this step, we are creating a Cloud Run service that will run this application in a container, granting public access to your service.

Step 6: Verify Functionality

Visit the provided URL to see your application in action. You can also test its functionality using curl:

curl -X POST -H "Content-Type: application/json" \
  -d '{"num1": 10, "num2": 50}' \
  https://[YOUR_CLOUD_RUN_URL]/add

{"result":60}
