google cloud run - how to deploy your app as container image

 

To deploy our app as container image, first we need the app and a dockerfile. A sample git repo for this can be found here (https://github.com/kepungnzai/gcp-cloud-run-python-fastapi).

And this is what the Dockerfile looks like:-

# Use the official lightweight Python image.

# https://hub.docker.com/_/python

FROM python:3.13.5-slim

# Allow statements and log messages to immediately appear in the Cloud Run logs

ENV PYTHONUNBUFFERED 1

# Create and change to the app directory.

WORKDIR /usr/src/app

# Copy application dependency manifests to the container image.

# Copying this separately prevents re-running pip install on every code change.

COPY requirements.txt ./

# Install dependencies.

RUN pip install -r requirements.txt

# Copy local code to the container image.

COPY . ./

# Run the web service on container startup.

CMD exec uvicorn main:app --host 0.0.0.0 --port $PORT

To get things going faster, you can deploy this from the command line using the followings:

gcloud builds submit --tag gcr.io/secondary-471605/my-fastapi-service

gcloud run deploy my-fastapi-service --image gcr.io/secondary-471605/my-fastapi-service

And you should see your app up and running.
