This gist will drive you through creating a Docker 1.12 Swarm cluster (with Swarm mode) on AWS infrastructure.

Prerequisites

You need a few things already prepared in order to get started. You need at least Docker 1.12 set up. I was using the stable version of Docker for mac for preparing this guide.

$ docker --version
Docker version 1.12.0, build 8eab29e

You also need Docker machine installed.

PSQL

Palabras mágicas:

psql -U postgres

Si ejecutas con la bandera -E, describirá las consultas subyacentes que se realizan con los comandos \ (genial para aprender).

La mayora de comandos \d soportan un parámetro adicional del __schema__.name__ y aceptan comodines como *.*
