Azure-Powershell 脚本错误（IP 地址增量）

Question

I hope you all doing well

can you please help me to solve this problem?

$ipnumber = 3
$RgName = "test"
$Location = "test"

for ($i = 0; $i -lt $ipnumber; $i++) {
    $res1 = -join ((1..10) | ForEach-Object { get-random -minimum 97 -maximum 122 | ForEach-Object { [char]$_ } })
    $res2 = -join ((1..10) | ForEach-Object { get-random -minimum 97 -maximum 122 | ForEach-Object { [char]$_ } })
    
    $PublicIP = '$PublicIP'
    $IpConfigName = '$IpConfigName'
    $IpConfig = '$IpConfig'
    $ip = '10.0.0.'
    $x = 25
    $PublicIP = $PublicIP + $i
    $IpConfigName = $IpConfigName + $i
    $IpConfig = $IpConfig + $i
    $x = 25 + $i
    $ip = $ip + $x
    #####################################
    # Create a public IP address
    $PublicIP = New-AzPublicIpAddress `

}

$rand6 = -join ((1..10) | ForEach-Object { get-random -minimum 97 -maximum 122 | ForEach-Object { [char]$_ } })

    -IpConfiguration $IpConfig0, $IpConfig1, $IpConfig2

Error1 : enter image description here

Error2 : New-AzNetworkInterface: C:\\Users\\Marouane\\Desktop\\testpowershell\\test2.ps1:95:22 Line | 95 | -IpConfiguration $IpConfig, $IpConfig0, $IpConfig1 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Cannot bind parameter 'IpConfiguration'. Cannot convert the "$IpConfig1" value of type "System.String" to type | "Microsoft.Azure.Commands.Network.Models.PSNetworkInterfaceIPConfiguration".

I want to increment the IP by 1 Ex : 10.0.0.25 next 10.0.0.26 next 10.0.0.27 but it says that you can't put in 'IpConfiguration' String ips So what should i do ? please help me!! Thank you

Answer 1

I think Mainich you are trying do the array operation.

If I understand correctly, you are trying to create to create an array of the below variable :

$PublicIP = $PublicIP + $i
$IpConfigName = $IpConfigName + $i
$IpConfig = $IpConfig + $i

For instance,

IpConfig1,Ipconfig2,Ipconfig3 - and store the value accordingly.

Unfortunately, the implementation is slightly wrong

Please note : I have detailed the operation only for the $ipconfig variable. You can extend the same to other variables like $IpConfigName,$PublicIP

What Exactly is Happening

For all the iteration, $IpConfig gets updated & the variables you intended IpConfig1,Ipconfig2,Ipconfig3 are not created through the above logic.

1. You are initializing the variable ipConfig as a string
2. Overwriting the value of the variable ipconfig with the string value $ipconfig1 (for the first iteration)
3. Overwriting the string value of the variable ipconfig with object.

AzNetworkInterfaceIpConfig

End of the iteration 1, $ipconfig is with the value AzNetworkInterfaceIpConfig ipconfig1 is non existant.

Suggestion :

The below creates an empty array with a fixed number - in your case 3 as $ipnumber = 3

$ipconfig = @() * $ipnumber

$ipconfig.append(New-AzNetworkInterfaceIpConfig `
    -Name <>`
    -Subnet<>`
    -PrivateIpAddress <> `
    -PublicIpAddress <>)

( or )

$ipconfig[0] = New-AzNetworkInterfaceIpConfig `
        -Name <>`
        -Subnet<>`
        -PrivateIpAddress <> `
        -PublicIpAddress <>

Now you can access the values through ipconfig[0], ipconfig[1],ipconfig[2] Or you can pass the $ipconfig directly - as the parameter Ip configuration accepts the array value

-IpConfiguration <PSNetworkInterfaceIPConfiguration[]>

Suggestion 2:

if you would prefer creating the variable on the fly like ipconfig1,ipconfig2,ipconfig3, then you could do the below :

New-Variable -Name "Ipconfig$i" -Value <>
New-Variable -Name "Ipconfig$i" -Value <>
Get-Variable -Name "Ipconfig$i" -ValueOnly
