docker-compose.yml for production - Django and Celery

Question

I'm looking to deploy a simple application which uses Django and celery.

docker-compose.yml:

version: "3.8" services: django: build: . container_name: django command: python manage.py runserver 0.0.0.0:8000 volumes: - .:/usr/src/app/ ports: - "8000:8000" environment: - DEBUG=1 - CELERY_BROKER=redis://redis:6379/0 - CELERY_BACKEND=djcelery.backends.database:DatabaseBackend depends_on: - redis celery: build: . command: celery -A core worker -l INFO volumes: - .:/usr/src/app environment: - DEBUG=1 - CELERY_BROKER=redis://redis:6379/0 - CELERY_BACKEND=djcelery.backends.database:DatabaseBackend depends_on: - django - redis redis: image: "redis:alpine" volumes: pgdata:

Dockerfile:

FROM python:3.7 WORKDIR /app ADD . /app #Install dependencies for PyODBC RUN apt-get update \ && apt-get install unixodbc -y \ && apt-get install unixodbc-dev -y \ && apt-get install tdsodbc -y \ && apt-get clean -y # install ODBC driver in docker image RUN apt-get update \ && curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add - \ && curl https://packages.microsoft.com/config/debian/10/prod.list > /etc/apt/sources.list.d/mssql-release.list \ && apt-get update \ && ACCEPT_EULA=Y apt-get install --yes --no-install-recommends msodbcsql17 \ && apt-get clean \ && rm -rf /var/lib/apt/lists/* \ && rm -rf /tmp/* # install requirements RUN pip install --trusted-host pypi.python.org -r requirements.txt EXPOSE 5000 ENV NAME OpentoAll CMD ["python", "app.py"]

When I run "docker-compose up" locally, the celery worker is run and I am able to go to localhost:8000 to access the API to make asynchronous requests to a celery task.

Now I'm wondering how can I deploy this to the cloud environment? What would be the image I would need to build and deploy? Thanks

When you say "cloud environment", do you have a specific setup in mind? You already have a Dockerfile that builds an image, so you would need to arrange to push it to a registry of some sort (Docker Hub, something your cloud provider hosts like ECR/ACR/GCR, ...). I'd recommend deleting the volumes: that overwrite the content in the image and testing this setup locally before trying to deploy to somewhere more involved. — David Maze

You will need to install an application server (eg. gunicorn) in your django container and then run it on say port 8000. You'll also need a webserver (eg. nginx) in a container or installed on the host. The web server will need to act as a reverse proxy for gunicorn and also serve your static Django content.
