dsc-test-bootstrap-cookbook

The purpose of this cookbook is to bootstrap up machines to test the DSC script resource

This cookbook installs powershell/git and pulls down a version of chef specified by attributes. It then uses that version of chef to run a recipe in local mode (Local mode is run with a different lock file)

Requirements

Platforms

• Windows 2012

Chef

• Chef 12+

Cookbooks

• windows
• powershell
• git
• chocolatey

Attributes

Key	Type	Description
['dsc-test-bootstrap']['github_owner']	String	The owner of the github repository for chef
['dsc-test-bootstrap']['github_repo']	String	The github repo containing chef
['dsc-test-bootstrap']['git_revision']	String	The git revision to checkout

Usage

Requirements

You will need to have knife, knife-azure, and knife-windows. At the time of writing this(knife windows latest release was 0.6.0 42c358e), knife-windows needed to be checked out and installed from https://github.com/opscode/knife-windows

bootstrap.ps1

Provided is a script to create a node in azure and register it to your chef server.

Below is an example of my knife.rb

current_dir = File.dirname(__FILE__)
log_level                :info
log_location             STDOUT
client_key               "#{current_dir}/jdmundrawala.pem"
validation_client_name   "mundrawala-test-validator"
validation_key           "#{current_dir}/mundrawala-test-validator.pem"
chef_server_url          "https://api.opscode.com/organizations/mundrawala-test"
cache_type               'BasicFile'
cache_options( :path => "#{ENV['HOME']}/.chef/checksums" )

knife[:azure_publish_settings_file] = "c:/users/Jay\ Mundrawala/myazure.publishsettings"
knife[:azure_vm_size] = "Medium"
knife[:azure_source_image] = "a699494373c04fc0bc8f2bb1389d6106__Windows-Server-2012-R2-201407.01-en.us-127GB.vhd"
knife[:azure_service_location] = "West US"
knife[:bootstrap_protocol] = "winrm"
knife[:winrm_user] = "myuser"
knife[:winrm_password] = "mypassword”

Start by getting the cookbook dependencies:

berks install

Upload the cookbooks to your chef server:

berks vendor
knife cookbook upload -a --cookbook-path .\berks-cookbooks\

Create a node in Azure and bootstrap it:

.\bootstrap.ps1 -NodeName mynode -PSVersion 5

Given the knife.rb file above, this command will create a server running windows 2012 in Azure. It will clone https://github.com/opscode/chef, and checkout platform/dsc-phase-1 because the defaults set in bootstrap.ps1

Param(
    [Parameter(Mandatory=$true)]
    [string]$NodeName,
    [string]$GithubOwner = "opscode",
    [string]$GithubRepo = "chef",
    [string]$GitRevision = "platform/dsc-phase-1",
    [string]$PSVersion = 4,
    [switch]$ClientRunOnly
)

Part of the bootstrap will run the version of chef client that was checked out from github. This will run

bundle exec chef-client -z test_recipe.rb > log

test_recipe.rb is in the files/default directory.

Now say you make a change to files/default/test_recipe.rb (or anything in this cookbook). If you do not require a clean machine, upload your updated cookbooks to your chef server, and run

.\bootstrap.ps1 -NodeName mynode -ClientRunOnly
