Hi All,
Is there anyone who has written a custom function calling powershell that
returns a value?
The case we are trying to use the puppet module *scheduled_task *and it
works really well!
The problem is that we don''t want to declare our password in the
declaration so we would like to set username and password with a task
performed after the task is registered.
Everything works almost fine except for when we set the user and password ,
the next runtime the scheduled_task resource will change back to system
since nothing is declared.
So everything runs everytime puppet agent runs.
We would like to a custom functions that checks if the scheduled_task is
created and runing under proper user. If that is the case we dont ned to
run *scheduled_task *resource.
So in pseudo code something like this:
$result = sheduledtaskexists("MyMagicTask")
unless $result
scheduled_task { ''MyMagicTask'':
ensure => present,
enabled => true,
command => ''d:\Scheduled_Tasks\MyMagicTask.bat'',
trigger => {
schedule => daily,
every => 1, # Defaults to 1
start_date => ''2011-08-31'', # Defaults to
''today''
start_time => ''03:00'', # Must be specified
}
}
end
module Puppet::Parser::Functions
newfunction(:sheduledtaskexists, :type => :rvalue) do |args|
argument =args[0].to_s() # "MyMagicTask"
cmd =
''C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile
-NonInteractive -NoLogo -ExecutionPolicy Bypass -Command .
d:\\tools\\check_task_exist.ps1; Task-Exists argument'' #should be repla
value = %x[ #{cmd} ].to_s().chomp
result = value
end
end
Powershell snippet... not proper code..
function Task-Exists([string]$taskname)
{
[Boolean]$isFound = $false
[xml]$tasks = schtasks /query /TN $taskname /XML
if($tasks)
{
$isFound = $true
}
$isFound
}
Has someone done something like this?

[Puppet Users] Re: Custom Function that uses powershell
Functions are executed on the PuppetMaster when compiling the catalog. I don''t think you can. You may try some workaround calling a powershell command from a custom fact and use the fact value to manage your logic.

Re: [Puppet Users] Re: Custom Function that uses powershell
The next version of facter will bring in executable external facts (which can be a powershell script) that would allow you to do the fact workaround. Another thing you can do is set environment variables on the machine that would contain user/pass and use those. And then there is also ENC On Fri, Sep 6, 2013 at 7:36 AM, Alessandro Franceschi <al@lab42.it> wrote:> Functions are executed on the PuppetMaster when compiling the catalog. > I don''t think you can. > You may try some workaround calling a powershell command from a custom > fact and use the fact value to manage your logic. > > > On Thursday, September 5, 2013 6:32:21 PM UTC+2, carllindelof wrote: >> >> Hi All, >> >> Is there anyone who has written a custom function calling powershell that >> returns a value? >> >> The case we are trying to use the puppet module *scheduled_task *and it >> works really well! >> >> The problem is that we don''t want to declare our password in the >> declaration so we would like to set username and password with a task >> performed after the task is registered. >> >> Everything works almost fine except for when we set the user and password >> , the next runtime the scheduled_task resource will change back to system >> since nothing is declared. >> >> So everything runs everytime puppet agent runs. >> >> We would like to a custom functions that checks if the scheduled_task is >> created and runing under proper user.
