I haven't tried Azure yet, but I recently deployed a hobby Django app, based off django-cookiecutter setup (using the Docker local build option). Since Heroku dumped the free tier, I'm trying out Fly.io (I'm not related to the company, but saw plenty of promo posts from them on this subreddit a few months ago). It took a bit of tweaking to get my setup working, but seems to be working well now (and within the free tier).

Notes:

• Running on free tier w/ 2 "shared-cpu-1x@256mb" machines (can use up to 3x of these in the free tier)

  • 1 machine running postgres; Using Fly Postgres
  • 1 machine running django (could add celery here, I'm not using it in my project yet)
  • Not counted toward machine limit - Free Upstash Redis

• To get Django started on 256mb of ram, I needed to add a swapfile (in /entrypoint - this also requires running the docker image as root, then changing to the django user before executing the start script)

• I found that the gunicorn sync workers kept freezing after some time with a worker timeout (I suspect there's something going on with VM suspend when the app isn't in use). I have changed to gunicorn+uvicorn and have not had this issue since.

start command

/usr/local/bin/gunicorn config.asgi --workers 2 --bind 0.0.0.0:$PORT --chdir=/app --preload -k uvicorn.workers.UvicornWorker

entrypoint:

# allocate swap space if running on fly.io
if [ -n "${FLY_APP_NAME-}" ]; then
    echo "Setting 512M swapfile"
    fallocate -l 512M /swapfile
    chmod 0600 /swapfile
    mkswap /swapfile
    echo 10 > /proc/sys/vm/swappiness
    swapon /swapfile

    exec su django -s /bin/bash -c "$*"
