This series of articles are to discuss a task to remove IIS Log Files. We start from doing the task manually, then make automation, and the last deploy the automation to pipelines (different servers):

A - Introduction

In the previous articles, we have introduced the VB Script to remove the IIS Log Files, and to automate the script running through Windows Task Scheduler. This article will automate the deployment of the task to different servers through pipeline. The content of this article will include

B - Create the Script to Remove IIS Log Files

We have done this job in the article

The script is

sLogFolders = Array("D:\LOGS\IIS\CRMHPE","D:\LOGS\IIS\Microsoft Dynamics CRM")
iMaxAge = 14   'in days
Set objFSO = CreateObject("Scripting.FileSystemObject")
For each sLogFolder in sLogFolders
	set colFolder = objFSO.GetFolder(sLogFolder)
	For Each colSubfolder in colFolder.SubFolders
			Set objFolder = objFSO.GetFolder(colSubfolder.Path)
			Set colFiles = objFolder.Files
			For Each objFile in colFiles
					iFileAge = now-objFile.DateCreated
					if iFileAge > (iMaxAge+1)  then
							objFSO.deletefile objFile, True
					end if
			Next
	Next
Next

C - Automate to trigger the Removing Script

We have done this job in the second article

where we made a Task Scheduler: Delete Log Files

with Actions:

and Trigger as Daily running

to Run the VB Script:

D - Automate the deployment of the Task

Now we try to automate the deployment process through pipeline by a ymal file (PowerShell Script).

First Step: Export a XML file from the Task Scheduler as an installation file:

This is the XML file:

<?xml version="1.0" encoding="UTF-16"?>
<Task version="1.2" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task">
  <RegistrationInfo>
    <Date>2024-10-13T17:05:07.8938926</Date>
    <Author>MAXCORP\502397</Author>
    <URI>\Delete Log Files</URI>
  </RegistrationInfo>
  <Triggers>
    <CalendarTrigger>
      <StartBoundary>2024-10-24T00:00:00</StartBoundary>
      <Enabled>true</Enabled>
      <ScheduleByDay>
        <DaysInterval>1</DaysInterval>
      </ScheduleByDay>
    </CalendarTrigger>
  </Triggers>

      <LogonType>Password</LogonType>

    <RunOnlyIfNetworkAvailable>false</RunOnlyIfNetworkAvailable>
    <IdleSettings>
      <StopOnIdleEnd>true</StopOnIdleEnd>
      <RestartOnIdle>false</RestartOnIdle>
    </IdleSettings>
    <AllowStartOnDemand>true</AllowStartOnDemand>
    <Enabled>true</Enabled>
    <Hidden>false</Hidden>
    <RunOnlyIfIdle>false</RunOnlyIfIdle>
    <WakeToRun>false</WakeToRun>
    <ExecutionTimeLimit>PT72H</ExecutionTimeLimit>
    <Priority>7</Priority>
  </Settings>
  <Actions Context="Author">
    <Exec>
      <Command>D:\LOGS\IIS\Log_File_Deletion.vbs</Command>
    </Exec>
  </Actions>
</Task>

Second Step: Create a PowerShell Script to Deploy

# Register a task to delete IIS Log Files 
Write-LogInfo "Begin to Register the Task Scheduler."

Add-ScheduledTaskFromXmlFile -XmlFile "$ScriptsPath\Delete Log Files.xml" -ServiceAccount $ServiceAccount -ErrorAction Stop

# copy the vbs file from $ScriptsPath to the local folder: D:\LOGS\IIS
$localDirectory = 'D:\LOGS\IIS'
Write-Host "Copy Log_File_Deletion.vbs from $ScriptsPath to $localDirectory"
$copiedFile = $ScriptsPath + "Log_File_Deletion.vbs"
Copy-Item $copiedFile -Destination $localDirectory

Write-LogInfo "Register Delete IIS Log Files Task Scheduler Successfully."

where

This piece of script will be in the install.ps1 associated with two files:

like this

The output will be like this
