Error when running from docker container

[mostopalove]

I'm trying to start my FastAPI server from a docker container, but it failed due to the following error:

INFO: Will watch for changes in these directories: ['/app']

Locally it works. I think I missed something in Dockerfile. This is my pyproject.toml:

And here Dockerfile:

I tried everything, but nothing helps, please help me figure it out

The problem was in Dockerfile. We should run this command at the beginning of file: RUN apt-get install pkg-config libxml2-dev libxmlsec1-dev libxmlsec1-openssl -y This is the correct version:

FROM python:3.10 as python-base

# SET ENV #
ENV PYTHONBUFFERED=1 \
    PIP_NO_CACHE_DIR="off" \
    POETRY_VERSION=1.4.0 \
    POETRY_HOME="/opt/poetry" \
    POETRY_VIRTUALENVS_IN_PROJECT=true \
    POETRY_NO_INTERACTION=1 \
    PYSETUP_PATH="/app" \
    VENV_PATH="/app/.venv"

ENV PATH="$POETRY_HOME/bin:$VENV_PATH/bin:$PATH"

RUN apt-get install pkg-config libxml2-dev libxmlsec1-dev libxmlsec1-openssl -y

FROM python-base as builder-base

# Build arg credentials
