How do you deploy a Django app in 2020?

I strongly recommend DigitalOcean.

They have a fantastic tutorial on deploying a Django app -> https://www.digitalocean.com/community/tutorials/how-to-set-...

You'll probably get 10 different answers here too.

I use uwsgi in emperor mode. I have a Makefile that runs a few SSH commands on production to clone my git repo at a specific commit, builds a virtual environment from requirements.txt, and atomically swaps a symlink to a uwsgi socket. Nginx in front of it all. It's pretty much the Python equivalent of FTPing HTML files to a web server.

Uwsgi is terrifying because it has so many options (and I wonder how secure it is), but it has never failed me. Packaging and containerizing things sounds cool, but I just can't justify spending time on it when my setup works fine (I'm a solo dev).

Package it; as a container or as containers that install a RPM/DEB/APK/Condapkg/Pythonpkg (possibly containing a zipapp). Zipapps are fast.

If you have any non-python dependencies, a Pythonpkg only solves for part of the packaging needs.

Producing a packaged artifact should be easy and part of your CI build script.

Here's the cookiecutter-django production docker-compose.yml with containers for django, celery, postgres, redis, and traefik as a load balancer: https://github.com/pydanny/cookiecutter-django/blob/master/%...

Cookiecutter-django also includes a Procfile.

With k8s, you have an ingress (~load balancer + SSL termination proxy) other than traefik.

You can generate k8s YML from docker-compose.yml with Kompose.

I just found this which describes using GitLab CI with Helm: https://davidmburke.com/2020/01/24/deploy-django-with-helm-t...

What is the command to scale up or down? Do you need a geodistributed setup (on multiple providers' clouds)? Who has those credentials and experience?

How do you do red/green or rolling deployments?

Can you run tests in a copy of production?

Can you deploy when the tests that run on git commit pass?

What runs the database migrations in production; while users are using the site?

If something deletes the whole production setup or the bus factor is 1, how long does it take to redeploy from zero; and how much manual work does it take?

CI + Ansible + Terraform + Kubernetes.

Whatever tools you settle on, django-eviron for a 12 Factor App may be advisable. https://github.com/joke2k/django-environ
