Cannot access ray serve app outside Docker

Hi guys! I’ve packaged up my ray application into a docker image and serve my application locally with serve run module:entrypoint. Within the docker, I can request the endpoints and get back my outputs but outside the docker and still on the same machine, I’m unable to ping the endpoint.

My dockerfile looks like:

FROM python:3.8



COPY requirements.txt /src/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /src/requirements.txt

COPY . /src

CMD ["serve", "run", "module:entrypoint", "--host", "", "--port", "8000"]

Does anyone know how to solve this? If I just remote into the container with docker run myimage -p 8000:8000 -p 8265:8265 and then run the app, I’m still unable to reach it outside the docker. This is the error I get when trying to ping it:
