Hosting Static Website on Google Cloud Run

Deployment of static websites was always fun, easy and free. But new options arrives every day.

Google announced Cloud Run - fully managed stateless HTTP containers which we can use instead of cheaper approach on Cloud Storage https://cloud.google.com/storage/docs/hosting-static-website .

Put these 2 files near public/ folder with your content.

app.py

# Testing locally: 
# $ python app.py
import os

from flask import Flask, request, send_from_directory

app = Flask(__name__)

@app.route('/', defaults={'path': ''})
@app.route('/<path:path>')
def send_static(path):
    if len(path)==0 or path[-1]=='/':
        return send_from_directory('public', f'{path}index.html')
    return send_from_directory('public', path)

if __name__ == "__main__":
    app.run(debug=True,host='0.0.0.0',port=int(os.environ.get('PORT', 8080)))

Dockerfile

# Use the official Python image.
# https://hub.docker.com/_/python
FROM python:3.6-alpine

# Install production dependencies.
RUN pip install Flask gunicorn

# Copy local code to the container image.
ENV APP_HOME /app
WORKDIR $APP_HOME
COPY app.py .
COPY ./public ./public


# Run the web service on container startup. Here we use the gunicorn
# webserver, with one worker process and 8 threads.
# For environments with multiple CPU cores, increase the number of workers
# to be equal to the cores available.
CMD exec gunicorn --bind :$PORT --workers 1 --threads 8 app:app

Then deploy on Cloud Run:

docker build -t gcr.io/[PROJECT-ID]/[SERVICE_NAME]:[TAG] .
docker push gcr.io/[PROJECT-ID]/[SERVICE_NAME]:[TAG]
gcloud beta run deploy [SERVICE_NAME] --image gcr.io/[PROJECT-ID]/[SERVICE_NAME]:[TAG] \
--concurrency=10 \
--region=us-central1 \
--allow-unauthenticated

Your site will be available to anybody (thanks to –allow-unauthenticated) by link like this https://mystatic-uydlcxd3aq-uc.a.run.app

Remind you once again: this approach is not free. You will need to pay for compute time and for storage (containers introduce additional overhead to size of your content). See more details on pricing here https://cloud.google.com/run/pricing
