Build a development environment with Poetry Django Docker Pycharm
Introduction
It's been a year since I started python, but I'm still not used to building a Python environment. Package managers in particular feel like the weakest of many languages. For some reason, when I tried to build a development environment on mac, an error related to OpenSSL occurred.
We have summarized how to build a development environment on docker to solve such problems.
The source is listed on Github.

Only the main files are described. Keep the files created by Django.

Dockerfile
FROM python:3.6.8
WORKDIR /usr/src/app
ENV POETRY_VERSION=1.0.10 \
PATH="/root/.poetry/bin:$PATH"
RUN curl -sSL https://raw.githubusercontent.com/sdispater/poetry/${POETRY_VERSION}/get-poetry.py | python && \
poetry config virtualenvs.create false
COPY ./pyproject.toml /usr/src/app/pyproject.toml
RUN poetry install
CMD tail -f /dev/null
docker-compose.yml
version: '3.5'
services:
app:
build:
context: ../
dockerfile: ./docker/Dockerfile
working_dir: /usr/src/app/mysite
command: python manage.py runserver 0.0.0.0:8000
volumes:
- ../mysite:/usr/src/app/mysite
ports:
- "8000:8000"
Run docker-compose from console
For the time being, check the operation with docker-compose up without Pycharm.
$ cd docker
$ docker-compose up -d
$ curl http://127.0.0.1:8000/
$ docker-compose down
hello1
Debug with Pycharm
Pycharm settings
Add Python Interpreter with docker-compose
Set the project Interpreter to docker-compose
Create a runserver in Configuration
The point is to set the parameter to runserver 0.0.0.0:8000
Debug with Pycharm
This will also stop the breakpoint. The file will be modified and reflected without restarting docker-compose.
At the end
This makes the host side clean. You can easily build a development environment.
