My way of integrating poetry to docker container

README.md

Poetry docker integration

I landed on using archlinux as my base image. I use chaoti-aur to install the latest poetry from git, I can choose the exact Python version I want thanks to pyenv (made it conveniant by adding this as an env var, PYTHON_VERSION).

You can install your poetry package after copying it to your WORKDIR by poetry install --no-dev. Flush the poetry cache by poetry cache clear --all; no neat way to do this yet #887.

Advantages of archlinux + poetry in containarized production

• Installing poetry through pacman installs the poetry as root. Poetry installer is rootless by default, which is not production-friendly; it is now! Don't forget to switch to a user wihtout write-access to root! Otherwise, you won't benefit from this safety feature.
• Separation of Python used for production code, and poetry code. Poetry will run on the latest stable version of Python, while production code will run on whatever version it was designed for.
• Less maintanance of dockerfile as the heavylifting for poetry compability is done by archlinux.

Stable release alternatives

Just replace pacman -Sy --noconfirm python-cleo-git python-poetry-git pyenv with pacman -Sy --noconfirm python-poetry pyenv.
