Azure-Powershell Script error (ip address increment ) - azure

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

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