How to deploy a FastAPI Project on Google Cloud Platform

This tutorial will guide you through the process of creating a FastAPI project from scratch and running it on Google Cloud Platform (GCP) using Artifact Registry and Cloud Run.


Before starting this tutorial, ensure you have the following:

  • A Google Cloud Platform account.
  • Google Cloud SDK installed on your local machine.
  • Basic knowledge of Docker and FastAPI.

Step 1: Create a FastAPI Project

Follow these steps to create a FastAPI project:

  1. Create a new directory for your project.
  2. Inside the project directory, create your FastAPI application according to your requirements (prefeable in a new virtual environment).

Step 2: Set Up Artifact Registry on GCP

  1. Go to the Google Cloud Platform console.
  2. Navigate to Artifact Registry.
  3. Click on “Create Repository” and provide a name for your repository.
  4. Set the region, format to Docker, and mode to Standard.
  5. Choose the location region (e.g., asia-southeast1).
  6. Click “Create”.

Step 3: Configure Docker

  1. Open the Docker on Google Cloud Platform.
  2. Click on “Setup instructions”.
  3. Follow the instructions to configure Docker with Google Cloud Registry, it should show something like that terminal code, copy and paste it in the terminal.
$gcloud auth configure-docker \

Step 4: Build and Push Docker Image

  1. Open your terminal and navigate to your project directory.
  2. Run the following commands, replacing placeholders with your actual values:
# Set environment variables
export PATH=$PATH:/Users/mahmoud/Desktop/google-cloud-sdk/bin/
export CLOUDSDK_PYTHON=python3


# Authenticate Docker with Google Cloud Registry
gcloud auth configure-docker $HOST_NAME

# Build Docker image

# Tag Docker image

# Push Docker image to Google Cloud Registry

Step 5: Deploy to Cloud Run

  1. Verify that the Docker image is successfully pushed to Artifact Registry.
  2. Go to Cloud Run and click on “Create Service”.
  3. Select your previously created image.
  4. Leave all settings as default and click “Create”.
  5. Ensure the port matches the one specified in your FastAPI application (e.g., 8000).


Congratulations! You have successfully created a FastAPI project from scratch and deployed it on Google Cloud Platform using Artifact Registry and Cloud Run.

Next Steps

You can now continue to develop your FastAPI application and utilize command-line tools for continuous deployment on Google Cloud Platform.
