Python Poetry

Run your python code easily using this docker image with the latest version of Python3.11 and Poetry pre-installed.

// TODO: add badges here

Usage

Use this docker image by mounting your code or repo, containing a pyproject.toml and main.py, in the /code volume in the container. Alternatively a different python file can be executed by changing the environment variable PYTHON_MAIN_FILE.

The docker image is available at the following container registries:

• Docker hub: hetorusnl/python-poetry
• Github container registry: ghcr.io/hetorusnl/python-poetry

Environment variables

// TODO: add table with environment variables here

Examples

To help you getting started, several examples using the docker cli and docker-compose are provided below.

Docker Run

The simplest example runs the container with the included example project:

docker run -it --rm hetorusnl/python-poetry

To run your own python file and stop the container after the script finishes, use the following snippet.
Supplying the PYTHON_MAIN_FILE environment variable is optional and it defaults to main.py.
Whether to supply a port to forward to the container depends on the functionality of your script, and can be added by adding this line to the docker run command above the image name: -p <external>:<internal> \ . This will expose port <internal> from inside the container to <external> on the host.

docker run -it --rm \
  -e PYTHON_MAIN_FILE=main.py \
  -v /path/to/project:/code \
  hetorusnl/python-poetry

To run a python file in the background and detach it from the terminal, use the following.

docker run -d --name=python-poetry \
  -e PYTHON_MAIN_FILE=main.py \
  -v /path/to/project:/code \
  hetorusnl/python-poetry

Docker Compose

Run this example docker compose file using docker compose up to attach it to the terminal, or docker compose up -d to run in the background and detach it from the terminal. This will run the example project, and is also available in the repository as docker-compose.yml

version: "3"

services:
  python-poetry-example:
    image: hetorusnl/python-poetry
    container_name: python-poetry-example

A more advanced docker compose example is shown below. Modify the environment, ports and volumes according to your application.

version: "3"

services:
  python-poetry-with-code:
    image: hetorusnl/python-poetry
    container_name: python-poetry-with-code
    environment:
      - PYTHON_MAIN_FILE=main.py # optional to run a different file
    ports:
      - 80:80 # optional, exposes port 80 from inside the container to the host
    volumes:
      - /path/to/project:/code # if not provided, runs the included example project

An example using the repo-cloning functionality of the container is shown below. Modify the related environment variables, ports and volumes according to your application. REPO_PREPARE_SCRIPT can be set to a script name in the repo, that is executed before running python.

version: "3"

services:
  python-poetry-with-repo:
    image: hetorusnl/python-poetry
    container_name: python-poetry-with-repo
    ports:
      - 8000:8000
    environment:
      - REPO_URL=https://github.com/<username>/<repo-name>
      - REPO_PREPARE_SCRIPT=./prepare.sh
