Powershell terminate chef-run


#1

Hi All,

I have a “Restart-computer -force” command as part of a powershell script inside a chef recipe, how do I terminate the chef-run at this point?

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) {
write-host “I am domain joined, aborting!”

 }

 Else {

  Add-Computer -DomainName $domain -Credential $cred -force

  Restart-Computer -force --- how do I terminate the chef-run here?

 }

}

else {

  code here.....

    Restart-Computer -force -- how do I terminate the chef-run here?

}

EOH

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]https://docs.chef.io/resource_common.html#guards
[1]https://docs.chef.io/resource_common.html#notifications
[2]https://docs.chef.io/resource_reboot.html

This will end the chef run cleanly, rather than throwing an error at the
end of the powershell.

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?

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

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]https://docs.chef.io/resource_common.html#guards

[2]https://docs.chef.io/resource_reboot.html

This will end the chef run cleanly, rather than throwing an error at the end of the powershell.

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?

Simon

Hi,

I managed to fix it by doing:

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]"

I know the powershell script is returning 1, but the reboot doesn’t seem
to happen:

I think you guys might be tackling the wrong problem (in trying to use output from a script). In order to accomplish the desired task (rename and join domain, then reboot - but only that once), we should go back to Galen’s suggestion.

Something like the below, where you’ve got a powershell script that will rename a computer and join the domain. However, rather than embedding the checks in the powershell script and relying on output, we can put the check in a guard clause. That will prevent the PowerShell script from running when the settings match our desired state. That also allows us to use a notification to tell the reboot resource to restart the computer when changes have been made, but only when the powershell script runs.

reboot ‘Restart Computer’ do
action :nothing
end
powershell_script ‘Rename and Join Domain’ do
code <<-EOH
…your rename and domain join logic here…
EOH
not_if <<-EOH
$ComputerSystem = gwmi win32_computersystem
($ComputerSystem.Name -like ‘#{node[‘some_attribute_that_has_the_new_name’]}’) -and
$ComputerSystem.partofdomain)
EOH
notifies :reboot_now, ‘reboot[Restart Computer]’, :immediately
end
