Rather than each scraper executing within a Python virtualenv as currently, they will each be in a Docker container. The scraper's Docker image will build upon (inherit) a base image owned by OCHA IT. The draft base image is here. It inherits from unocha/alpine-base:3.8 and contains a Python 3 environment suitable for running scrapers - it includes HDX Python API library, awesome-slugify and Pandas (including its dependencies on Scipy and Numpy). An example scraper that inherits this base image is the FTS scraper.

There is some private information that is needed by the scrapers to run. Currently it resides in a private OCHA GitHub repository, but it will be moved to Ansible.

The setup will comply with OCHA IT's Hosting in Shared Infrastructure: Project Requirements document.
