trying to setup a new docker compose and its not working, it just exits after starting up.

that first env var for the db connection string doesnt look right, we dont have any settings that have double underscores

Just ran the one your provided and i get this error

thats because its referencing my file `work.py` instead of starting the worker process that I mentioned you'd want to swap this for in the other thread

youd want something like this instead
```  worker:
    image: prefecthq/prefect:2-python3.11
    restart: always
    command: ["prefect", "worker", "start", "--pool", "your-pool"]```

also it seems your image is perhaps a prefect 1 image? `--host` should be a valid flag for `prefect server start` in prefect 2.x

was using this <https://hub.docker.com/r/prefecthq/prefect> , thought it would have been the most up to date.

if i wanna use the most recent prefect, which docker image should i use? prefecthq/prefect:2-python3.12 ?

yep! thatd be latest prefect 2.x for 3.12
