It is a little known fact, that docker was presented the first time to the world in a demo by Solomon Hykes at the PyCon US in Santa Clara in 2013. Furthermore, docker-compose (formerly known as Fig) is entirely written in python. This may lead to the impression, that docker and python is pure love and a match made in heaven. While for some use-cases this is true. But local development of python code inside a docker container is surprisingly broken, at least if you want to do it right.
In this talk I will walk you through the proper setup of a local python development environment using docker. Including sane packaging, testing, automated setup in version control, IDE integration, docker-compose and more. I will share with you all the tiny surprises I encountered and you might have stumbled over yourself already too. As a spoiler, I will not be able to give nice solutions to all of them. But it might help you, to not feel stupid the next time you face one of them: Good news, probably it’s not you!
