Yeah, we are using poetry for our production API. Initially we thought that it’s cool idea, but apparently, it’s not that simple. 
For example, building Dockerfiles is a giant problem. If you are not going to commit your lock file, installing dependencies will take forever (~20 minutes for us). Second problem is that dependencies are installed into hidden venv, which you need to solve by either tricking poetry into installing dependencies globally by disabling virtualenvs, using multi-stage (<a href="https://github.com/python-poetry/poetry/issues/1178" target="_blank" rel="noopener nofollow">https://github.com/python-poetry/poetry/issues/1178</a>) or exporting deps into requirements.txt anyway. 
And it gets even worse if you want to deploy to the server instead of dealing with docker. Now you need to setup CI/CD pipeline to export deps, then build package if you are whl/module setup enjoyer, install it on the server using pip and deal with relocking and reinstalling half of the server deps if something is changed in you <code>pyproject.toml</code>. 
But maybe I’m missing something, and this can be done differently.

Good stuff! It’s nice seeing Python move in a more standard, package-based direction
