Description
===========

This cookbook provides resources and providers to create an manage
Windows Azure components. Currently supported resources are:

* Storage Accounts ('azure_storage_account')
* Blob Storage Containers ('azure_storage_container')
* SQL Azure Servers ('azure_sql_db_server')

**Note** This cookbook uses the `azure` RubyGem to interact with the
Azure API. This gem requires `nokogiri` which requires compiling
native extensions, which means build tools are required.

Requirements
============

Requires Chef 0.7.10 or higher for Lightweight Resource and Provider
support. Chef 0.8+ is recommended. While this cookbook can be used in
`chef-solo` mode, to gain the most flexibility, we recommend using
`chef-client` with a Chef Server.

A Windows Azure account is required. The Management Certificate and
Subscriptoin ID are used to authenticate with Azure.

Azure Credentials
===============

In order to manage Azure components, authentication credentials need
to be available to the node. There are a number of ways to handle
this, such as node attributes or roles. We recommend storing these in
a databag (Chef 0.8+), and loading them in the recipe where the
resources are needed.

DataBag recommendation:

% knife data bag show azure main
{
"id": "main",
"management_certificate": "YOUR PEM FILE CONTENTS",
"subscription_id": "YOUR SUBSCRIPTION ID"
}

This can be loaded in a recipe with:

azure = data_bag_item("azure", "main")

And to access the values:

azure['management_certificate']
azure['subscription_id']

We'll look at specific usage below.

Recipes
=======

default.rb
----------

The default recipe installs the `azure` RubyGem, which this cookbook
requires in order to work with the Azure API. Make sure that the azure
recipe is in the node or role `run_list` before any resources from
this cookbook are used.

"run_list": [
"recipe[azure]"
]

The `gem_package` is created as a Ruby Object and thus installed
during the Compile Phase of the Chef run.

Resources and Providers
=======================

This cookbook provides three resources and corresponding providers.

## storage_account.rb


Manage Azure Storage Accounts with this resource.

Actions:

* `create` - create a new storage account
* `delete` - delete the specified storage account

Attribute Parameters:

* `management_certificate` - PEM file contents of Azure management
certificate, required.
* `subscription_id` - ID of Azure subscription, required.
* `management_endpoint` - Endpoint for Azure API, defaults to
`management.core.windows.net`.
* `location` - Azure location to create storate account. Either
location or affinity group are required.
* `affinity_group_name` - Affinity group to create account in. Either
location or affinity group are required.
* `geo_replication_enabled` - True or false, defaults to true.

## storage_container.rb

Manage Azure Blob Containers with this resource

Actions:

* `create` - create a new container
* `delete` - delete the specified container

Attribute Parameters:

* `storage_account` - Account to create container in, required.
* `access_key` - Access key for storage account, required.

## sql_db_server.rb

Actions:

* `create` - create a new server. Use the Azure location as the `name`
of the storage account. The server name is autogenerated.

Attribute Parameters:

* `management_certificate` - PEM file contents of Azure management
certificate, required.
* `subscription_id` - ID of Azure subscription, required.
* `management_endpoint` - Endpoint for Azure API, defaults to
`management.database.windows.net`.
* `login` - Desired admin login for db server, required.
* `password` - Desired admin password for db server, required.
* `server_name` - This attribute is set by the provider, and can be
used by consuming recipies.

Usage
=====

The following examples assume that the recommended data bag item has
been created and that the following has been included at the top of
the recipe where they are used.

include_recipe "azure"
azure = data_bag_item("azure", "main")

## azure_storage_accouint

This will create an account named `new-account` in the `West US`
location.

azure_storage_account 'new-account' do
management_certificate azure['management_certificate']
subscription_id azure['subscription_id']
location 'West US'
action :create
end

This will create an account named `new-account` in the existing
`my-ag` affinity group.

azure_storage_account 'new-account' do
management_certificate azure['management_certificate']
subscription_id azure['subscription_id']
affinity_group_name 'my-ag'
action :create
end

## azure_storage_container

This will create a container named `my-node` within the storage
account `my-account`.

azure_storage_container 'my-node' do
storage_account 'my-account'
access_key azure['access_key']
action :create
end

## azure_sql_db_server

This will create a db server in the location `West US` with the login
`admin` and password `password`.

azure_sql_db_server 'West US' do
management_certificate azure['management_certificate']
subscription_id azure['subscription_id']
login 'admin'
password 'password'
action :create
end

Here is an example of how you might retrieve the generated server
name.

file '/etc/db_server_info' do
content lazy {
db2 = resources("azure_sql_db_server[West US]")
"Url: https://#{db2.server_name}.database.windows.net"
}
mode 0600
action :create
end
