A Docker base image for Satis.
For a complete Satis image, you will need to build a container image
inheriting from this one. Besides adding /etc/satis.json,
you will need to do one of two things:
- create a cron job (and run cron!) to run regular Satis updates
- run a single Satis update when building your container image - this will result in a static/fixed package archive
