Hi prefect community (and @Marvin), today I was updating my local docker files by pulling the latest prefect3 image. The relevant part of my docker-compose file looks like:
Copy code
### Prefect Server API and UI
  server:
    image: prefecthq/prefect:3-python3.12-conda
    restart: always
    volumes:
      - prefect:/root/.prefect
    entrypoint: ["/opt/prefect/entrypoint.sh", "prefect", "server", "start"]
    environment:
      #- PREFECT_UI_URL=<http://127.0.0.1:4200/api>
      - PREFECT_API_URL=<http://127.0.0.1:4200/api>
      # If you want to access Prefect Server UI from anywhere other than the Docker host machine, you will need to change
      # PREFECT_UI_URL and PREFECT_API_URL to match the external hostname/IP of the host machine. For example:
      #- PREFECT_UI_URL=<http://external-ip:4200/api>
      #- PREFECT_API_URL=<http://external-ip:4200/api>
      - PREFECT_SERVER_API_HOST=0.0.0.0
      - PREFECT_API_DATABASE_CONNECTION_URL=<postgresql+asyncpg://postgres:postgres@database:5432/prefect>
      # Uncomment the following line if you want to use the 'S3 Bucket' storage block instead of the older 'S3' storage
      # - EXTRA_PIP_PACKAGES=prefect-aws
    ports:
      - 4200:4200
    depends_on:
      - database
    profiles: ["server"]
starting the updated containers with docker compose resulted in the following Error (I truncated the message, but hope having kept the important information):
Copy code

Any ideas, why there is this 
_distutils_hack
module missing ? Is it maybe a problem of the conda image ? Any others having this issue ? THANKS for your help !

@Marvin here the short version for you:
Copy code
File "/opt/conda/envs/prefect/lib/python3.12/socket.py", line 976, in

It seems you're encountering a 
ModuleNotFoundError
for the module 
_distutils_hack
. This module is typically required by 
setuptools
, a package used for building and distributing Python packages. Here's how you might resolve this issue: 1. Ensure 
setuptools
is installed: Run the following command to install or update 
setuptools
in your environment:
Copy code
bash
   pip install --upgrade setuptools
2. Check your Python environment: Make sure you're operating within the correct Python environment where all necessary packages are installed. 3. Verify your environment setup: If you're using Docker or a similar setup, ensure that the environment is correctly configured and all dependencies are installed within the container. If the problem persists, please provide more context about your setup, such as how you're running your Python application (e.g., using Docker, virtual environments, etc.), and any specific actions you've already taken.

@Marvin I am facing the error, running the official prefect 3 docker image: prefecthq/prefect:3-python3.12-conda

It seems there are no reported issues in the Prefect GitHub repository regarding a 
ModuleNotFoundError
for 
_distutils_hack
with the official Prefect 3 Docker image (
prefecthq/prefect:3-python3.12-conda
). Here are a few steps you can take to troubleshoot and potentially resolve the issue: 1. Rebuild the Docker Image: Sometimes, rebuilding the Docker image can resolve transient issues. You can do this by pulling the latest image:
Copy code
bash
   docker pull prefecthq/prefect:3-python3.12-conda
2. Check for Updates: Ensure that you have the latest version of the Docker image. Prefect may have released updates or patches that resolve this issue. 3. Install Missing Package: You can try running a shell in the Docker container and manually installing any missing packages:
Copy code
bash
   docker run -it prefecthq/prefect:3-python3.12-conda /bin/bash
   conda install -c conda-forge setuptools
4. Review Docker Configuration: Verify that your Docker setup and configuration align with the official Prefect documentation for using their Docker images. If these steps do not resolve the issue, consider reaching out to the Prefect community or support channels for more targeted assistance.

My image is up-to-date. I cannot run the container, since it fails starting ;(
