Chef on Windows Azure

Chef Community - community.opscode.com

15,000+ registered users

800 individual contributors

150 corporate contributors

500+ cookbooks

Support for on-Premise Windows and Windows Azure in the Cloud


Chef on Windows Azure - Architecture

• Chef Server – Authentication

and Cookbooks

• Windows Azure –endorsed Linux packages

• New VM – loads workstation

• New workstation – loads client and recipes


github.com/opscode/knife-azure


Example Knife Command

Create Jenkins running on Ubuntu on an Azure VM knife azure server create

Creates a new Azure Server

--hosted-service-name JenkinsDemo1 Names the Server

--role-name DemoServer Names the Role

--run-list 'recipe[java],recipe[jenkins]‘ Retrieves a run-list, recipes, runs on Chef Client


Puppet on Windows Azure

The power of Puppet = Community!

Demand for better windows integration and management

>1850 modules in the Forge alone

Strong Third Party Ecosystem

Vagrant

Test locally before you pay for cloud resources

Puphpet – from workstation to cloud

UI that helps generate a Vagrant file and Puppet manifests


Puppet on Windows Azure -Architecture

Flavors Enterprise Puppet

OSS Puppet

Terminology Module

Manifest

Tools Facter

Dashboard

Forge

Geppetto

Cloudsmith


forge.puppetlabs.com/msopentech/windowsazure



The Windows Azure Puppet module

Virtual Machines – both Linux and Windows

Virtual Networks – create logically isolated sections of Azure and securely connect them to your on premise clients and servers

SQL Server – create and maintain your SQL database



Manifest files

Collections of definitions, references and commands

Deploy VMs in a defined “desired state”.

bootstrap.pp – allows the creation of a new Puppet node

db.pp – create a new instance of SQL server

init.pp – defines a Windows Azure class that will allow easy deployment to the associated Windows Azure account

vm.pp – create a new virtual machine instance from a virtual machine image

vnet.pp – create a new virtual network


Example Modules

Modules are just directories with files, arranged in a specific, predictable structure

Ala run list in Chef

site.pp

include ntp

include apache

include mysql

include mongodb

include build_essential

Storing Data

2 Examples:

Azure Storage

Table Storage


Windows Azure Storage

Storage in the Cloud

Scalable, durable, and available

Anywhere at anytime access

Only pay for what the service uses

RESTful Web Services

Use from Windows Azure Compute

Use from anywhere on the internet

Applicationbuilding blocks


Azure Data Management


Storage Libraries in Many Languages


Setting up Storage

• Configure Your Application to Access Storage• Download and use the Ruby azure package, which communicates with the storage REST

services.

• Use RubyGems to obtain the package

• Use a command-line interface such as PowerShell (Windows), Terminal (Mac), or Bash (Unix).

• Type "gem install azure" in the command window to install the gem and dependencies.

• Import the package

• Using your favorite text editor, add the following to the top of the Ruby file where you intend to use storage:

• require "azure"


Storage Connection

• Setup a Windows Azure Storage Connection

• The azure module will read the environment variables AZURE_STORAGE_ACCOUNT and AZURE_STORAGE_ACCESS_KEY for information required to connect to your Windows Azure storage account.

• If these environment variables are not set, you must specify the account information before using Azure Storage Services with the following code:

Azure.config.storage_account_name = "<your azure storage account>"

Azure.config.storage_access_key = "<your azure storage access key>"


Getting Storage Credentials

• To obtain the Account Name and Access Key values:

• Log into the Windows Azure Management Portal.

• Navigate to the storage account you want to use

• Click MANAGE KEYS at the bottom of the navigation pane.

• In the pop up dialog, you will see the storage account name, primary access key and secondary access key. For access key, you can either the primary one or the secondary one.

Storing Data

Azure Storage

Table Storage


Azure Storage Concepts


Create a Container

azure_blob_service = Azure::BlobService.new

begin

container =

azure_blob_service.create_container("test- container")

#Optional – Set Container to public read acess

azure_blob_service.set_container_acl('test-

container', "container")

rescue

puts $!

End


Upload a Blob to a Container

content = File.open("test.png", "rb") { |file|

file.read }

blob =

azure_blob_service.create_block_blob(container.name,

"image-blob", content)

puts blob.name


List the Blobs in a Container

containers =

azure_blob_service.list_containers()

containers.each do |container|

blobs =

azure_blob_service.list_blobs(container.name

)

blobs.each do |blob|

puts blob.name

end

end


Download or Delete a Blob

#Download

blob, content =

azure_blob_service.get_blob(container.name,"

image-blob")

File.open("download.png","wb") {|f|

f.write(content)}

#Delete

azure_blob_service.delete_blob(container.nam

e, "image-blob")


Storing Data

2 Examples:

Azure Storage

Table Storage


Table Storage Concepts


No Fixed Schema


Create a Table

azure_table_service =

Azure::TableService.new

begin

azure_table_service.create_table("testtable

")

rescue

puts $!

end


Add or Update an Entity

#Add

entity = { "content" => "test entity",

:PartitionKey => "test-partition-key",

:RowKey => "1" }

azure_table_service.insert_entity("testtabl

e", entity)


Update an Entity

#update

entity = { "content" => "test entity with

updated content",

:PartitionKey => "test-partition-key",

:RowKey => "1" }

azure_table_service.update_entity("testtabl

e", entity)


Process Groups of Entities

azure_table_service = Azure::TableService.new

batch =

Azure::Storage::Table::Batch.new("testtable",

"test-partition-key") do

insert "2", { "content" => "new content 2" }

insert "3", { "content" => "new content 3" }

end

results = azure_table_service.execute_batch(batch)


Query Entities

#Single

result =

azure_table_service.get_entity("testtable", "test-

partition-key",

"1")

#Multiple

query = { :filter => "PartitionKey eq 'test-

partition-key'" }

result, token =

azure_table_service.query_entities("testtable",

query)


Query a Subset of Entities

query = { :filter => "PartitionKey eq 'test-

partition-key'",

:select => ["content"] }

result, token =

azure_table_service.query_entities("testtable",

query)


Deleting

#Entity

azure_table_service.delete_entity("testtable",

"test-partition-key", "1")

#Table

azure_table_service.delete_table("testtable")
