When we begin new rails project,
always need easy, fast database setting
Docker-postgres-rails gem easy, fast run PostgreSql database by docker without docker command and many environment var

Required

• Your OS must be macOS or linux (Not support window, because using mkdir)
• Installed Docker
• Rails project must use PostgreSql (You can create new project using postgresql by this command : $ rails new [PORJECT_NAME] -d postgresql )
• Your must input values of database, username, password, port in config/database.yml file (docker will use these values)

Getting Started

1. Add gem in Gemfile https://rubygems.org/gems/docker-postgres-rails

   gem 'docker-postgres-rails', '~> 0.0.1'

   OR

   gem 'docker-postgres-rails', :git => "git://github.com/x1wins/docker-postgres-rails.git"

2. Generate docker_pg.rake

   $ rails generate docker_pg
      identical  lib/tasks/docker_pg.rake

3. Set database, username, password, port in database.yml,
   Docker will use database, username, password, port in database.yml

     database: docker_postgres_rails_development
     username: docker_postgres_rails
     password: mysecretpassword
     host: localhost
     port: 5432

4. Create database volume path

   $ rake docker:pg:init

5. Run dockerized PostgreSQL

   $ rake docker:pg:run

   $ docker ps
   CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
