PostgreSQL role for Ansible

A role for deploying and configuring PostgreSQL and extensions on unix hosts using Ansible.

It can additionally be used as a playbook for quickly provisioning hosts.

Vagrant machines are provided to produce a boxed install of PostgreSQL or a VM for integration testing.

Supports

Supported PostgreSQL versions:

PostgreSQL 9.4
PostgreSQL 9.3

Supported targets:

Ubuntu 14.04 LTS "Trusty Tahr"
Ubuntu 12.04 LTS "Precise Pangolin"
Debian (untested)
RedHat (untested)

Installation methods:

Binary packages from the official repositories at postgresql.org

Available extensions (under a switch):

Development headers - postgresql_dev_headers
Contrib modules - postgresql_contrib
PostGIS - postgresql_postgis

Usage

Clone this repo into your roles directory:

$ git clone https://github.com/zenoamaro/ansible-postgresql.git roles/postgresql

And add it to your play's roles:

- hosts: ...
  roles:
    - postgresql
    - ...

This roles comes preloaded with almost every available default. You can override each one in your hosts/group vars, in your inventory, or in your play. See the annotated defaults in defaults/main.yml for help in configuration. All provided variables start with postgresql_.

You can also use the role as a playbook. You will be asked which hosts to provision, and you can further configure the play by using --extra-vars.

$ ansible-playbook -i inventory --extra-vars='{...}' main.yml

To provision a standalone PostgreSQL box, start the boxed VM, which is a Ubuntu 12.04 box:

$ vagrant up boxed

You will find PostgreSQL listening on the VM's 5432 port on address 192.168.33.20 in the private network. You can then connect to it as any user. Please note that this is highly insecure, so if you're going to publish this VM you'll want to provide actual authentication.

Run the tests by provisioning the appropriate VM:

$ vagrant up test-ubuntu-trusty

At the moment, the following test boxes are available:

test-ubuntu-precise
test-ubuntu-trusty

Still to do

Add repositories, tasks and test VMs for other distros
Allow installation from sources if requested
Add support for different PostgreSQL versions (9.4+)
Add support for PostgreSQL clusters
Add support for PgBouncer
Try to make the boxed VM more secure by default
Add links to the relevant documentation in configuration files
Provide a library of custom modules
