Ref: http://www.maori.geek.nz/post/boot_2_docker_how_to_set_up_postgres_elasticsearch_and_redis_on_mac_os_x

Execute following Commands in shell [Mac Os]

brew install boot2docker
boot2docker init boot2docker up
Important: Watch the output; Following lines are needed for setup
To connect the Docker client to the Docker daemon, please set:

    export DOCKER_HOST=tcp://192.168.59.103:2376

    export DOCKER_CERT_PATH=<dir>/.boot2docker/certs/boot2docker-vm

    export DOCKER_TLS_VERIFY=1

Setup:

 Execute the suggestion from `boot2docker up`

 And,  export DOCKER_IP=`boot2docker ip`

Run Postgres: 

Note: Change to desired password

docker run -it -e POSTGRES_PASSWORD=password -p 5432:5432 postgres

Stop Postgres:

Use 'Ctrl+C' to stop Postgrs server

Stop docker:

boot2docker stop

Rerun Docker/Postgres:

boot2docker up
Re-establish setup, if needed

docker run -it -e POSGRES_PASSWORD=password -p 5432:5432 postgres

Access:

pgAdmin3 - Use 'DOCKER_IP' address and 'postgres' user, password used in 'docker run'

For psql - With pgadmin3 installation

export PATH=$PATH:/Applications/pgAdmin3.app/Contents/SharedSupport

psql -h $DOCKER_IP -U postgres

Persistance

No persistence with above setup; Good for RoR Devels.
