There is another method for getting output from powershell in chef. I can't
remember what its called, but, maybe a "mixin?" In any case, you don't
actually "see" powershell running in a chef run. Until you find the special
"logging chef foo" stuff, you could try doing something like "The command
is $command" | out-file c:\cheflog.txt -append
Hi Chris,
No what I mean is, I have this in my recipe:
I’ve highlighted key parts of the logic so it makes sense.
::Chef::Resource::PowershellScript.send(:include,
Chef::Mixin::PowershellOut)
include_recipe 'windows::reboot_handler'
reboot "reboot_machine" do
action :nothing
reason "reason"
other params as appropriate
end
powershell_script "rename_hostname" do
code <<-EOH
…
if ($computer_name -eq $new_name) {
Write-host "Not changing the name as it is already set"
if ((gwmi win32_computersystem).partofdomain -eq $true) {
write-host "I am domain joined, aborting!"
…
}
Else {
Add-Computer -DomainName $domain -Credential $cred -force
$rebootNeeded = 1
return $rebootNeeded
}
}
else {
$sysInfo = Get-WmiObject -Class Win32_ComputerSystem
$sysInfo.Rename($new_name)
$rebootNeeded = 1
return $rebootNeeded
}
EOH
cmd = powershell_out(code)
puts "This value is #{cmd}"
if cmd.stdout == 1
notifies :request_reboot, "reboot[reboot_machine]"
end
end
It’s the code block starting “cmd cmd = powershell_out(code)” which is
supposed to get the return value back, so this if statement evaluates
if cmd.stdout == 1
notifies :request_reboot, "reboot[reboot_machine]"
end
But it doesn’t seem to do anything, so I added: “puts "This value is
#{cmd}" to see if cmd had any contents and on the chef run it doesn’t even
output “this value is” (the text itself) to the console, let alone the
variable.
Any idea why? Do I have to have an import statement to get ruby code to
work in a recipe?
Cheers,
Simon

For powershell
Write-Host “This value is #{cmd}”

Also, if I put:
puts "This value is #{cmd}"
It doesn’t write anything to the screen on the Chef run either?
Cheers,
Simon.

Hi,
I managed to fix it by doing:
::Chef::Resource::PowershellScript.send(:include,
Chef::Mixin::PowershellOut)
However, the following block doesn’t seem to work:
EOH
cmd = powershell_out(code).stdout.chop
if cmd == 1
notifies :request_reboot, "reboot[reboot_machine]"
end
I know the powershell script is returning 1, but the reboot doesn’t seem
to happen:

The powershell variable is called $rebootNeeded and that returns 1 in the
code logic.
Maybe my if statement is wrong?
Cheers,
Simon.

I would use the chef reboot resource.
In short, put a guard on the powershell_script resource similar to your if
statement[0]
And then I'd use a notifies[1] for the reboot resource[2]
[0]Common Resource Functionality
[1]Common Resource Functionality
[2]reboot Resource
This will end the chef run cleanly, rather than throwing an error at the
end of the powershell.

Hi All,
I have a “Restart-computer -force” command as part of a powershell script

I have something like this:
if ($computer_name -eq $new_name) {
Write-host "Not changing the name as it is already set"
… code here….
if ((gwmi win32_computersystem).partofdomain -eq $true) {
