I will demonstrate how to deploy a simple container on cloud run.
Cloud Run is a fully managed platform that enables you to run your code directly on top of Google’s scalable infrastructure. Cloud Run is simple, automated, and designed to make you more productive.
I followed official fastapi doc to spin up a hello world app
Create a requirements.txt file
fastapi[standard] pydantic>=2.7.0,<3.0.0
from typing import Union from fastapi import FastAPI app = FastAPI() @app.get("/") def read_root(): return {"Hello": "World"} @app.get("/items/{item_id}") def read_item(item_id: int, q: Union[str, None] = None): return {"item_id": item_id, "q": q}
Create a Dockerfile
FROM python:3.9 WORKDIR /code COPY ./requirements.txt /code/requirements.txt RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt COPY ./app /code/app CMD ["fastapi", "run", "app/main.py", "--port", "80"]
GitHub Action
In order for the GitHub actions process to pick up the YAML file, there’s specific location for it to live. Each repository using actions requires a directory structure called /.github/workflows
*Configure this workflow with GCP more info *
# This workflow build and push a Docker container to Google Artifact Registry # and deploy it on Cloud Run when a commit is pushed to the $default-branch # branch. # # To configure this workflow: # # 1. Enable the following Google Cloud APIs: # # - Artifact Registry (artifactregistry.googleapis.com) # - Cloud Run (run.googleapis.com) # - IAM Credentials API (iamcredentials.googleapis.com) # # You can learn more about enabling APIs at # https://support.google.com/googleapi/answer/6158841. # # 2. Create and configure a Workload Identity Provider for GitHub: # https://github.com/google-github-actions/auth#preferred-direct-workload-identity-federation. # # Depending on how you authenticate, you will need to grant an IAM principal # permissions on Google Cloud: # # - Artifact Registry Administrator (roles/artifactregistry.admin) # - Cloud Run Developer (roles/run.developer) # # You can learn more about setting IAM permissions at # https://cloud.google.com/iam/docs/manage-access-other-resources # # 3. Change the values in the "env" block to match your values.
Create a file google-cloudrun-docker.yml

Directory Structure
You should now have a directory structure like:
├── app │ ├── __init__.py │ └── main.py ├── Dockerfile └── requirements.txt └── requirements.txt ├── .github │ ├── workflows ├── google-cloudrun-docker.yml
> 1. Create a new repo in gitHUb > 2. Push your exisisting code to new repository on default branch
