Full Description

PostgreSQL docker image based on Alpine Linux

This repo builds a docker image that accepts the same env vars as the
official postgres build but
with a much smaller footprint. It achieves that by basing itself off the tiny
official alpine linux image. It also stores the data within the container rather than the host, so images
can be created to capture the state of the database. The primary purpose is development.

This image works in the same way the official postgres docker image work.

It's documented on DockerHub in it's README:

For example, you can start a basic PostgreSQL server, protected by a password,
listening on port 5432 by running the following:

$ docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d stespaway/postgres

Next, you can start you app's container while linking it to the PostgreSQL
container you just created giving it access to it.

$ docker run --name some-app --link some-postgres:postgres -d application-that-uses-postgres

Your app will now be able to access POSTGRES_PORT_5432_TCP_ADDR and POSTGRES_PORT_5432_TCP_PORT environment variables.
