You’re right, it was outdated. It seems I got mixed up after a fresh OS install on my Pi. I used APT to download and install docker which is extremely outdated. I now have proper repositories set up for both docker and nginx and everything is up to date. I didn’t need to make any changes to the dockerfile with the proper version.

I’m having issues getting nginx, pyfedi.service and celery.service to work.

Below are some snippets from my notes which should lay out all the steps I’ve taken, hopefully that will explain where I am currently at.

Steps from fresh OS Install:

## Apt software  
sudo apt install ddclient gufw -y  

# ddclient -> Account/Password/Domain Address  
# gufw  

## Repository Software  
# Docker -> Install-> https://docs.docker.com/engine/install/debian/  
# nginx -> Install -> https://nginx.org/en/linux_packages.html#Debian  
        -> sudo nano /etc/nginx/nginx.conf  
           -> Add line -> include /etc/nginx/sites-enabled/DOMAINNAME;  
        -> sudo nano /etc/nginx/sites-enabled/DOMAIN -> Copy DOMAINNAME reverse proxy settings from USB  
        -> sudo nginx -t  
        -> sudo service nginx restart  

## Docker Images  
# PieFed -> Install: Easy/Docker -> https://codeberg.org/rimu/pyfedi/src/branch/main/INSTALL.md  
  ->Edit file entries  
    -env.docker  
     -> SECRET_KEY='k3avh6fp'  
     -> SERVER_NAME='pi.DOMAINNAME.ca:5000'  
    -compose.yaml  
     -> ports: - '8030:5000' -> - '5000:5000'  

## Running In Production  
# Virtual Environment -> Gunicorn & Celery  
  -> python -m venv ~/home/USERNAME/pyfedi/venv  
  -> source ~/home/USERNAME/pyfedi/venv/bin/activate  
  -> pip3 install gunicorn celery  
  -> deactivate  
# Copy file celery_worker.default.py -> celery_worker.py  
  -> Change -> DATABASE_URL -> postgresql+psycopg2://piefed:piefed@db/piefed  
  -> Change -> SERVER_NAME -> pi.DOMAINNAME.ca:5000  
# Create Background Service Files -> Copy EACH from USB  
  -> sudo nano /etc/systemd/system/pyfedi.service  
  -> sudo nano /etc/systemd/system/celery.service  
  -> sudo nano /etc/default/celeryd  
# Enable/Start Background Services  
  -> sudo systemctl enable pyfedi.service  
  -> sudo systemctl enable celery.service  
  -> sudo systemctl start pyfedi.service  
  -> sudo systemctl start celery.service

/etc/nginx/sites-enabled/DOMAIN file:

    # fail_timeout=0 means we always retry an upstream even if it failed

    keepalive_timeout 30;  
    ssi off;

        proxy_set_header Connection "";  
        proxy_pass http://app_server;  
        ssi off;  
    }  

    # Serve static files directly with nginx  
    location ~* /static/ {  
        alias /home/USERNAME/pyfedi/app/static/;  
        expires max;  
        access_log off;  
    }
