Copy this docker-compose.yml file

services:
  pretalx:
    image: pretalx/standalone:latest
    container_name: pretalx
    restart: unless-stopped
    depends_on:
      - redis
      - db
    volumes:
      - ./conf/pretalx.cfg:/etc/pretalx/pretalx.cfg:ro
      - pretalx-data:/data
      - pretalx-public:/public
    ports:
      - "16800:80"
    environment:
      # Hint: Make sure you serve all requests for the `/static/` and `/media/` paths when debug is False. See [installation](https://docs.pretalx.org/administrator/installation/#step-7-ssl) for more information
      PRETALX_FILESYSTEM_MEDIA: /public/media

    restart: always
    volumes:
      - pretalx-db:/var/lib/postgresql/data
    expose:
      - "5432"
    environment:
      POSTGRES_PASSWORD: yourdbpassword # same password as one that you will put in pretalx.cfg file later on
      POSTGRES_USER: pretalx
      POSTGRES_DB: pretalx

  redis:
    image: redis:latest
    container_name: pretalx-redis

    volumes:
      - pretalx-redis:/data

volumes:
  pretalx-db:
  pretalx-data:
  pretalx-public:
  pretalx-redis:


Copy this to conf/pretalx.cfg (replace site URL, and mail configuration to fit your needs)

[filesystem]
# use PRETALX_FILESYSTEM_* env vars

[site]
debug = False
url = https://yoursite.com

[database]
backend = postgresql
name = pretalx
user = pretalx
password = yourdbpassword
host = pretalx-db
port = 5432

[mail]
from = your@yourmail.com
host = your.youremail.com
port = 25
user = userp@youremail.com
password = youremailpassword
tls = True
#ssl = True

[celery]
backend = redis://pretalx-redis/1
broker = redis://pretalx-redis/2

[redis]
location=redis://pretalx-redis/0

Start everything with docker compose up -d and to stop docker compose down
Visit your site URL after setting revers proxy on port 16800 and ssl (best solution this days Nginx Proxy Manager)
Set up a user and an organizer by running docker exec -ti pretalx pretalx init.
Set up a cronjob for periodic tasks like this 15,45 * * * * docker exec pretalx pretalx runperiodic

And in the end, as we use docker volumes, don't run this without full backup of VM/SERVER.
