@Marvin How can I setup Prefect server 3.x using docker-compose

To set up Prefect server 3.x using Docker Compose, you can follow these steps: 1. Run PostgreSQL: Start by setting up a PostgreSQL instance using Docker. Run the following command to start the PostgreSQL container:

sh
docker run -d --name prefect-postgres -v prefectdb:/var/lib/postgresql/data -p 5432:5432 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=yourTopSecretPassword -e POSTGRES_DB=prefect postgres:latest

2. Create a Docker Compose YAML File: Create a

docker-compose.yml

file with the following content:

yaml
version: "3"

services:
  db:
    image: postgres:latest
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=yourTopSecretPassword
      - POSTGRES_DB=prefect
    ports:
      - "5432:5432"
    volumes:
      - db:/var/lib/postgresql/data

  prefect:
    image: prefecthq/prefect:3.0.0-py3.8
    command: prefect server start --host 0.0.0.0
    environment:
      - PREFECT_LOGGING_LEVEL=DEBUG
      - PREFECT_API_DATABASE_CONNECTION_URL=<postgresql+asyncpg://postgres:yourTopSecretPassword@db:5432/prefect>
    ports:
      - "4200:4200"
    depends_on:
      - db

  worker:
    image: prefecthq/prefect:3.0.0-py3.8
    working_dir: /app
    command: python -m your_task_module
    volumes:
      - .:/app
    environment:
      - PREFECT_API_URL=<http://prefect:4200/api>
      - PREFECT_LOGGING_LEVEL=DEBUG

volumes:
  db:

Make sure to replace

your_task_module

with the module you want to run. 3. Configure Prefect: Set up your Prefect configuration to point to the new PostgreSQL database and Prefect API URL by running the following commands:

sh
prefect config set PREFECT_API_DATABASE_CONNECTION_URL="<postgresql+asyncpg://postgres:yourTopSecretPassword@localhost:5432/prefect>"
prefect config set PREFECT_API_URL="<http://127.0.0.1:4200/api>"

4. Start Docker Compose: Navigate to the directory containing your

docker-compose.yml

file and run:

sh
docker-compose up -d

This will start the PostgreSQL database, Prefect server, and worker services. For more detailed instructions and further configurations, you can visit the following links: - Self-Hosting Prefect - Sample GitHub Issue Discussion
