You should be using a start script for your app. You should not be running alembic in the docker file since it will only perform migrations when the container builds and not when the container is run. The startup script may look something like:

#!/bin/sh
set -e

PORT=${PORT:-8001}

alembic upgrade head

uvicorn app.main:app --host "::" --port "$PORT"

#!/bin/sh
set -e

PORT=${PORT:-8001}

alembic upgrade head

uvicorn app.main:app --host "::" --port "$PORT"

Then update the dockerfile to look something like:

FROM python:3.11

WORKDIR /app

COPY . /app

RUN pip install --no-cache -r requirements.txt

CMD ["/bin/sh", "/app/start.sh"]

FROM python:3.11

WORKDIR /app

COPY . /app

RUN pip install --no-cache -r requirements.txt

CMD ["/bin/sh", "/app/start.sh"]

As for why your app won't start, there are a few possible causes: - Does your app have an app module? If it does then in your source code root directory you will have a directory called app with a file called __init__.py in it. - If you have any life cycle hooks (on startup, on shutdown) make sure that you are not stopping the server - It is possible that you are doing something in your code that causes the worker process to be killed. This can happen if you allocate too much memory or use bugged python APIs. For example, I had an issue a couple years ago where using Thread and ThreadPoolExecutor in the same process caused python to silently shutdown like you are experiencing now. - If your asgi config is invalid, for example you have workers set to 0.

It uses xmlrpc.server.SimpleXMLRPCServer. When they construct the server they use a ipv4-style tuple (len = 2) and not a ipv6-style tuple (len = 4) https://stackoverflow.com/questions/5358021/establishing-an-ipv6-connection-using-sockets-in-python https://github.com/unoconv/unoserver/blob/master/src/unoserver/server.py#L88

Thanks for the help gang. Got it to work. Unfortunately unoserver only supports ipv4 address binding so I had to use socat to create a dual-stack proxy in the docker container, but it works now! Appreciate the help!

ah interesting did not know that private networking requires ipv6 address binding. Let me try that. Here is a link to unoserver. It is a document conversion service. https://github.com/unoconv/unoserver

That error was when I used the private URL. (unoserver.railway.internal)
