【问题描述】:
我正在审查一个脚本,该脚本应该删除一个虚拟机以及归属于该虚拟机的所有资源
Write-Host -NoNewline -ForegroundColor Green "Please enter the VM name you would like to remove:"
$VMName = Read-Host
$vm = Get-AzVm -Name $VMName
if ($vm) {
$RGName=$vm.ResourceGroupName
Write-Host -ForegroundColor Cyan 'Resource Group Name is identified as-' $RGName
#boot diagnostics container auto generated in storage account. Auto delete this storageURI property
$diagSa = [regex]::match($vm.DiagnosticsProfile.bootDiagnostics.storageUri, '^http[s]?://(.+?)\.').groups[1].value
Write-Host -ForegroundColor Cyan 'Marking Disks for deletion...'
$tags = @{"VMName"=$VMName; "Delete Ready"="Yes"}
$osDiskName = $vm.StorageProfile.OSDisk.Name
$datadisks = $vm.StorageProfile.DataDisks
$ResourceID = (Get-Azdisk -Name $osDiskName).id
New-AzTag -ResourceId $ResourceID -Tag $tags | Out-Null
if ($vm.StorageProfile.DataDisks.Count -gt 0) {
foreach ($datadisks in $vm.StorageProfile.DataDisks){
$datadiskname=$datadisks.name
$ResourceID = (Get-Azdisk -Name $datadiskname).id
New-AzTag -ResourceId $ResourceID -Tag $tags | Out-Null
}
}
if ($vm.Name.Length -gt 9){
$i = 9
}
else
{
$i = $vm.Name.Length - 1
}
$azResourceParams = @{
'ResourceName' = $VMName
'ResourceType' = 'Microsoft.Compute/virtualMachines'
'ResourceGroupName' = $RGName
}
$vmResource = Get-AzResource @azResourceParams
$vmId = $vmResource.Properties.VmId
$diagContainerName = ('bootdiagnostics-{0}-{1}' -f $vm.Name.ToLower().Substring(0, $i), $vmId)
$diagSaRg = (Get-AzStorageAccount | where { $_.StorageAccountName -eq $diagSa }).ResourceGroupName
$saParams = @{
'ResourceGroupName' = $diagSaRg
'Name' = $diagSa
}
Write-Host -ForegroundColor Cyan 'Removing Boot Diagnostic disk..'
if ($diagSa){
Get-AzStorageAccount @saParams | Get-AzStorageContainer | where {$_.Name-eq $diagContainerName} | Remove-AzStorageContainer -Force
}
else {
Write-Host -ForegroundColor Green "No Boot Diagnostics Disk found attached to the VM!"
}
Write-Host -ForegroundColor Cyan 'Removing Virtual Machine-' $VMName 'in Resource Group-'$RGName '...'
$null = $vm | Remove-AzVM -Force
Write-Host -ForegroundColor Cyan 'Removing Network Interface Cards, Public IP Address(s) used by the VM...'
foreach($nicUri in $vm.NetworkProfile.NetworkInterfaces.Id) {
$nic = Get-AzNetworkInterface -ResourceGroupName $vm.ResourceGroupName -Name $nicUri.Split('/')[-1]
Remove-AzNetworkInterface -Name $nic.Name -ResourceGroupName $vm.ResourceGroupName -Force
foreach($ipConfig in $nic.IpConfigurations) {
if($ipConfig.PublicIpAddress -ne $null){
Remove-AzPublicIpAddress -ResourceGroupName $vm.ResourceGroupName -Name $ipConfig.PublicIpAddress.Id.Split('/')[-1] -Force
}
}
}
Write-Host -ForegroundColor Cyan 'Removing OS disk and Data Disk(s) used by the VM..'
Get-AzResource -tag $tags | where{$_.resourcegroupname -eq $RGName}| Remove-AzResource -force | Out-Null
Write-Host -ForegroundColor Green 'Azure Virtual Machine-' $VMName 'and all the resources associated with the VM were removed sucessfully...'
}
else{
Write-Host -ForegroundColor Red "The VM name entered doesn't exist in your connected Azure Tenant! Kindly check the name entered and restart the script with correct VM name..."
}
我有一个问题:这段代码到底是做什么的:
$diagSa = [regex]::match($vm.DiagnosticsProfile.bootDiagnostics.storageUri, '^http[s]?://(.+?)\.').groups[1].value
我知道它与存储 uri 匹配,但如何匹配?为什么需要这个?我不确定 .groups[1].value 指的是什么
