带变量的Invoke-Command -asJob

Question

I am trying to use Invoke-Command -asJob to run a PS1 with arguments on a list of remote machines, and I am having a bugger of a time getting variables to work. As I understand it the code block that runs remotely cannot normally use local variables, but I have found a number of solutions that seem like they are supposed to solve the problem. I started with this, but it has the local variables.

foreach ($machine in $Machines) {
    Invoke-Command -computerName:$machine –scriptblock {
        & powershell.exe  -executionpolicy bypass -file $filePath -jobsfile $jobsFile
    } -credential:$credential  -authentication:CredSSP –asJob -jobName:$machine > $null
}

I also tried using -argumentList where $arguments includes the two arguments that contain variables. (I also tried a variant of that where -Path is a literal and and just the -jobFile argument for the PS1 is included in arguments.)

foreach ($machine in $Machines) {
    Invoke-Command -computerName:$machine -argumentList:$arguments –scriptblock {
        & powershell.exe  -executionpolicy bypass
    } -credential:$credential  -authentication:CredSSP –asJob -jobName:$machine > $null
}

Lastly I tried the using: approach.

foreach ($machine in $Machines) {
    Invoke-Command -computerName:$machine –scriptblock {
        & powershell.exe  -executionpolicy bypass -file $using:filePath -jobsfile $using:jobsFile
    } -credential:$credential  -authentication:CredSSP –asJob -jobName:$machine > $null
}

So far nothing works, so any pointers are greatly appreciated.

Answer 1

for remote powershell if you are in workgroup in clients run powershell as administrator

Enable-PSRemoting -Force

for configure trust host for connect you should trusted from clients

Set-Item wsman:\localhost\client\trustedhosts *

reset winrm service

Restart-Service WinRM

now you can use

Invoke-Command -ComputerName COMPUTER -ScriptBlock { COMMAND } -credential USERNAME

you should configure firewall for winrm you can use this method for run your script

$script = {Get-EventLog -LogName System -Newest 10 | where { $_.Index -ge 5071811 } | sort Index}

then

[System.Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes( $script))

get encoded command and use like

powershell -encodedcommand **encoded**

that is possible when you enter with psremoting

Enter-PSSession -ComputerName COMPUTER -Credential USER

your code:

foreach ($machine in $Machines) {
    Invoke-Command -computerName:$machine –scriptblock {
        & powershell.exe  -executionpolicy bypass -file $using:filePath -jobsfile $using:jobsFile
    } -credential:$credential  -authentication:CredSSP –asJob -jobName:$machine > $null
}

my code:

$s = New-PSSession -ComputerName Server1.Domain44.Corpnet.Fabrikam.com -Credential Domain01\Admin01
Invoke-Command -FilePath c:\scripts\test.ps1 -session $s -Asjob

Answer 2

So, the working solution was

foreach ($machine in $Machines) {
    Invoke-Command -computerName:$machine -argumentList: $filePath, $jobsFile –scriptblock {
        param (
            [String]$file,
            [String]$jobsFile
        )
        & powershell.exe  -executionpolicy bypass -file $file -jobsFile $jobsFile
    } -credential:$credential  -authentication:CredSSP –asJob -jobName:$machine > $null
}
