Ursula

Ursula provides a series of Ansible playbooks for installing, managing and maintaining OpenStack powered clouds.

Ursula was originally created by a team at Blue Box and is released under the MIT License (MIT).

Installation

We recommend using virtualenv or virtualenvwrapper to isolate your Python environment. Once that's complete, use the following:

git clone [email protected]:blueboxgroup/ursula.git
cd ursula
sudo bin/install-ubuntu || sudo bin/install-osx

Pre-Requisites

Ursula requires that you have access to a minimum of 3 hosts running ubuntu 12.04, and you can ssh to them from your workstation.

Dev/Test Environment Running on VMs / Vagrant

Please see this doc for more information on getting started.

Setup

Create a new environment, keep it somewhere outside this repo:

cp envs/example /your/env

Add your hosts to the inventory:

$editor /your/new/env/hosts

Getting Started

Ursula comes bundled with Vagrant hooks to get started. see docs/vagrant.md for using it.

Basic Usage

## Run the main playbook to install and configure all the things
ursula /your/new/env site.yml

Environments

An environment consists of two things:

  • hosts: a host inventory
  • group_vars: a directory of env-specific vars

To create a new env, copy the example env directory, and edit it to suit your needs:

cp -r envs/example /some/private/dir
# edit /some/private/dir/hosts, /some/private/dir/group_vars/all.yml

Support for proxy servers

There are a few attributes that allow you to use a proxy server in several different ways.

Enable proxy only during the ansible run

This sets the http_proxy environment variable in /etc/environment for the duration of the ansible run.

common.ansible_proxy: http://10.230.7.181:3128

Set proxy during ansible run and leave it there

This sets the http_proxy environment variable in /etc/environment but does not remove it like the above.

common.global_proxy: http://10.230.7.181:3128

Enable proxy only for APT

This sets your proxy only for apt repositories:

common.apt_cache: http://10.230.7.181:3128
