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.
