What is it?

A Vagrant configuration that starts up a PostgreSQL database in a virtual machine for local application development.

Installation

First install [Vagrant] and Virtual Box.

Then, run the following to create a new PostgreSQL app dev virtual machine:

# Clone it locally:
$ git clone https://github.com/jackdb/pg-app-dev-vm myapp

# Enter the cloned directory:
$ cd myapp

# Delete the old .git and README:
$ rm -rf README.md .git

# Optionally edit the database username/password:
$ $EDITOR Vagrant-setup/bootstrap.sh

Usage

# Start up the virtual machine:
$ vagrant up

# Stop the virtual machine:
$ vagrant halt

What does it do?

It creates a virtual server running Ubuntu 14.04 with the latest version of PostgreSQL (as of writing 9.4) installed. It also edits the PostgreSQL configuration files to allow network access and creates a database user/database for your application to use.

Once it has started up it will print out how to access the database on the virtual machine. It will look something like this:

$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
[... truncated ...]
Your PostgreSQL database has been setup and can be accessed on your local machine on the forwarded port (default: 15432)
  Host: localhost
  Port: 15432
  Database: myapp
  Username: myapp
  Password: dbpass

Admin access to postgres user via VM:
  vagrant ssh
  sudo su - postgres

psql access to app database user via VM:
  vagrant ssh
  sudo su - postgres
  PGUSER=myapp PGPASSWORD=dbpass psql -h localhost myapp

Env variable for application development:
  DATABASE_URL=postgresql://myapp:dbpass@localhost:15432/myapp

Local command to access the database via psql:
  PGUSER=myapp PGPASSWORD=dbpass psql -h localhost -p 15432 myapp

Why use the shell provisioner?

Or alternatively, why not Chef, Puppet, Ansible, or Salt?

Mainly because it's simple and anybody with a basic knowledge of shell scripting can tweak the bootstrap.sh to their liking.
