RabbitMQ service not found when running pytest with poetry

[natelastname]

Problem

As the generated README.md suggests, I am running postgres with the command:

docker run -p "5432:5432" -e "POSTGRES_PASSWORD=readapp2" -e "POSTGRES_USER=readapp2" -e "POSTGRES_DB=readapp2" postgres:16.3-bullseye

and then attemping to run pytest via the command poetry run pytest -vv . The problem is that 2/5 of the tests (the ones defined in the file test_rabbit.py) fail because it cannot resolve the ampq url for the rabbitMQ service.

After messing with it a bit, I cannot figure out an easy way to launch an instance of rabbitMQ as a stand-alone container.

Full output

I'll note that this might not be an essential fix since debugging via container still works.
It could potentially be resolved tweaking the README.

I'd suggest you to run the whole test-suite with docker-compose.

To do so you can just run

docker-compose run --build --rm api pytest -vv .

This command will work for sure, because that's how I test if all configurations work. The only note here is that you might want to update env variables.

Can confirm that this method still works.

A bit of background in case anyone else runs into this issue- The reason I wanted to run the tests using Poetry is because I wanted to have my personal .pdbrc file loaded during PDB debugging sessions. This provides the ability to use QOL features such as tab completion and aliases in PDB. I found out that it is possible to achieve this via modifying the Dockerfile:

FROM python:3.11.4-slim-bullseye AS prod
RUN apt-get update && apt-get install -y \
  gcc \
  && rm -rf /var/lib/apt/lists/*


RUN pip install poetry==1.8.2

# Configuring poetry
RUN poetry config virtualenvs.create false
RUN poetry config cache-dir /tmp/poetry_cache

# Copying requirements of a project
COPY pyproject.toml poetry.lock /app/src/

######################################
# Copy dotfiles
COPY dotfiles/.pdbrc dotfiles/.pdbrc.py /root
######################################

WORKDIR /app/src

# Installing requirements
RUN --mount=type=cache,target=/tmp/poetry_cache poetry install --only main
# Removing gcc
RUN apt-get purge -y \
  gcc \
  && rm -rf /var/lib/apt/lists/*

# Copying actuall application
COPY . /app/src/
RUN --mount=type=cache,target=/tmp/poetry_cache poetry install --only main

CMD ["/usr/local/bin/python", "-m", "readapp2"]

FROM prod AS dev

RUN --mount=type=cache,target=/tmp/poetry_cache poetry install

Closing the issues, because you found a way to solve it. Thanks for your response.
