Docker images of postgresql using alpine linux.
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.

Why?

$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
alpine-postgres     latest              82d0ddb748fd        About an hour ago   27.35 MB
alpine              latest              70c557e50ed6        5 weeks ago         4.798 MB
percona             latest              70588d0c4cd4        4 weeks ago         308.6 MB

Usage

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

It's documented on DockerHub in it's README: https://hub.docker.com/_/postgres/.

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 kiasaki/alpine-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.
