The Hydra image is built on top of Spilo. Spilo is a containerization of Postgres designed to be run in a production environment. The Hydra build adds extensions and modifies certain configuration files to enable those extensions.
Please see DEVELOPERS.md for information on building the image.
Hydra is only possible by building on the shoulders of giants.
