How do I upgrade a Chef SQL Server Cookbook to use Enterprise Edition? - sql-server-2012

Question

I've got a Chef cookbook from GitHub. It installs SQL Server 2012 Standard Edition. Our DBA has upgraded our database code to utilize features that can only be found on SQL Server 2012 Enterprise Edition. Since this cookbook is used to generate our test environments, we must now alter this cookbook to deploy SQL Server 2012 Enterprise.
Looking at the helper.rb file in the cookbook,
require 'chef/mixin/shell_out'
module SqlServer
class Helper
extend Chef::Mixin::ShellOut
def self.firewall_rule_enabled?(rule_name=nil)
cmd = shell_out("netsh advfirewall firewall show rule \"#{rule_name}\"")
cmd.stderr.empty? && (cmd.stdout =~ /Enabled:\s*Yes/i)
end
def self.sql_server_url(version, x86_64)
if x86_64
case version
when '2008R2'
'http://download.microsoft.com/download/D/1/8/D1869DEC-2638-4854-81B7-0F37455F35EA/SQLEXPR_x64_ENU.exe'
when '2012'
'http://download.microsoft.com/download/8/D/D/8DD7BDBA-CEF7-4D8E-8C16-D9F69527F909/ENU/x64/SQLEXPR_x64_ENU.exe'
end
else
case version
when '2008R2'
'http://download.microsoft.com/download/D/1/8/D1869DEC-2638-4854-81B7-0F37455F35EA/SQLEXPR32_x86_ENU.exe'
when '2012'
'http://download.microsoft.com/download/8/D/D/8DD7BDBA-CEF7-4D8E-8C16-D9F69527F909/ENU/x86/SQLEXPR_x86_ENU.exe'
end
end
end
it seems that it gets the install media from
http://download.microsoft.com/download/8/D/D/8DD7BDBA-CEF7-4D8E-8C16-D9F69527F909/ENU/x64/SQLEXPR_x64_ENU.exe
When I look on MSDN (which we have access to) I don't see that the Enterprise Edition is available to download as a .EXE, only as an .ISO.
How can I alter this cookbook to deploy from an ISO instead of a EXE, assuming that I have full access to the ISO?

Answer 1

Re-write second half of the server.rb
Download the ISO from repo
remote_file 'C:\LocalPath' do
source
end
Mount the ISO (you can also use Chef built-in mount resource)
powershell_script 'mount_it' do
code <<-EOH
Mount-DiskImage -ImagePath "C:\PATH\TO\ISO\FILE"
EOH
end
Use MixLib::ShellOut and get the Drive name (if you don't have it hardcoded mount with a drive letter), replace the part ##### with the volume name.
output = Mixlib::ShellOut.new('(gwmi -Class Win32_LogicalDisk | Where-Object {$_.VolumeName -eq "#####"}).DeviceID')
drive_name = output.run_command.stdout
Once you know the drive the ISO mounts on, then you will be able to find the local path to the installation .EXE file.
Install using windows_package or powershell_script block

Answer 2

Quoting the attributes file from your link
# Set these to specify the URL, checksum, and package name. Otherwise, the cookbook will
# use default values based on the value of node['sql_server']['version'] and the
# server architecture (x86 or x64).
default['sql_server']['server']['url'] = nil
default['sql_server']['server']['checksum'] = nil
default['sql_server']['server']['package_name'] = nil
So you just have to set those values to a local package (on a internal http server for example) in a wrapper cookbook for this cookbook to install the enterprise version.
