Fabien Bochu - Grocker, a Python build chain for Docker Grocker is a Docker build chain for Python. It transforms your Python package into a self-contained Docker image which can be easily deployed in a Docker infrastructure. Grocker also adds a Docker entry point to easily start your application. ----- At Polyconseil, we build Paris electric car sharing service: Autolib'. This system is based on many services developed using web technologies, Django and our own libraries to handle business logic. Packaging is already a difficult problem, deploying large Python projects is even more difficult. When deploying on a live and user- centric system like Autolib', you cannot rely on Pip and external PyPI servers which might become unavailable and are beyond your control. In the beginning we used classic Debian packaging: it was a maintenance hell. It took hours to build our packages and update their metadata to match our Python packages. So we switched to Docker. Docker allows us to have a unique item that is deployed in production systems: code updates are now atomic and deterministic! But before deploying the Docker image, you need to build it. That's where Grocker comes in. Grocker is a Docker build chain for Python. It will transform your Python package into a self-contained Docker image which can be easily deployed in a Docker Infrastructure. Grocker also adds a Docker entry point to easily start your application.
