#+TITLE: Database setup


This directory contains necessities for initializing and running a database
locally inside a docker container.

We want our development environment to use the same tech stack that production
uses. So rather than support a development configuration that uses SQLite and a
production configuration that uses PostgreSQL, just use PostgreSQL for both.
With Docker, it's easy.


Building requires the following environment variables.

- `POSTGRES_DB`
- `POSTGRES_USER`
- `POSTGRES_PASSWORD`

Running requires the following environment variables.

- `PGDATA`
- `POSTGRES_USER`
- `POSTGRES_PASSWORD`
