Snabbstart: Skapa en privat Lösning för Azure DNS med Bicep

Den här snabbstarten beskriver hur du använder Bicep för att skapa Azure DNS Private Resolver.

Bicep är ett domänspecifikt språk (DSL) som använder deklarativ syntax för att distribuera Azure-resurser. Det ger koncis syntax, tillförlitlig typsäkerhet och stöd för återanvändning av kod. Bicep erbjuder den bästa redigeringsupplevelsen för dina infrastruktur-som-kod-lösningar i Azure.

Följande bild sammanfattar den allmänna konfiguration som används. Adressintervall för undernät som används i mallar skiljer sig något från de som visas i bilden.

Förutsättningar

Om du inte har någon Azure-prenumeration skapar du ett kostnadsfritt konto innan du börjar.

Granska Bicep-filen

Bicep-filen som används i den här snabbstarten kommer från Azure-snabbstartsmallar.

Den här Bicep-filen är konfigurerad för att skapa en:

• Virtuellt nätverk
• DNS-matchare
• Inkommande och utgående slutpunkter
• Vidarebefordra regler och regeluppsättningar.

Sju resurser definieras i den här mallen:

• Microsoft.Network/virtualnetworks
• Microsoft.Network/dnsResolvers
• Microsoft.Network/dnsResolvers/inboundEndpoints
• Microsoft.Network/dnsResolvers/outboundEndpoints
• Microsoft.Network/dnsForwardingRulesets
• Microsoft.Network/dnsForwardingRulesets/forwardingRules
• Microsoft.Network/dnsForwardingRulesets/virtualNetworkLinks

Distribuera Bicep-filen

1. Spara Bicep-filen som main.bicep på den lokala datorn.
2. Distribuera Bicep-filen med antingen Azure CLI eller Azure PowerShell

CLI

az group create --name exampleRG --location eastus
az deployment group create --resource-group exampleRG --template-file main.bicep

PowerShell

New-AzResourceGroup -Name exampleRG -Location eastus
New-AzResourceGroupDeployment -ResourceGroupName exampleRG -TemplateFile ./main.bicep

När distributionen är klar bör du se ett meddelande som anger att distributionen lyckades.

Verifiera distributionen

Använd Azure-portalen, Azure CLI eller Azure PowerShell för att lista de distribuerade resurserna i resursgruppen.

CLI

#Show the DNS resolver
az dns-resolver show --name "sampleDnsResolver" --resource-group "sampleResourceGroup"

#List the inbound endpoint
az dns-resolver inbound-endpoint list --dns-resolver-name "sampleDnsResolver" --resource-group "sampleResourceGroup"

#List the outbound endpoint
az dns-resolver outbound-endpoint list --dns-resolver-name "sampleDnsResolver" --resource-group "sampleResourceGroup"

PowerShell

#Show the DNS resolver
Get-AzDnsResolver -Name "sampleDNSResolver" -ResourceGroupName "sampleResourceGroup"

#List the inbound endpoint list
Get-AzDnsResolverInboundEndpoint -DnsResolverName "sampleDnsResolver" -ResourceGroupName "sampleResourceGroup"

#List the outbound endpoint
Get-AzDnsResolverOutboundEndpoint -DnsResolverName "sampleDnsResolver" -ResourceGroupName "sampleResourceGroup"

Rensa resurser

När du inte längre behöver det använder du Azure-portalen, Azure CLI eller Azure PowerShell för att ta bort resurserna i följande ordning.

Ta bort DNS-matcharen

CLI

#Delete the inbound endpoint
az dns-resolver inbound-endpoint delete --dns-resolver-name "sampleDnsResolver" --name "sampleInboundEndpoint" --resource-group "exampleRG"

#Delete the virtual network link
az dns-resolver vnet-link delete --ruleset-name "sampleDnsForwardingRuleset" --resource- group "exampleRG" --name "sampleVirtualNetworkLink"

#Delete DNS forwarding ruleset
az dns-resolver forwarding-ruleset delete --name "samplednsForwardingRulesetName" --resource-group "exampleRG"

#Delete the outbound endpoint
az dns-resolver outbound-endpoint delete --dns-resolver-name "sampleDnsResolver" --name "sampleOutboundEndpoint" --resource-group "exampleRG"

#Delete the DNS resolver
az dns-resolver delete --name "sampleDnsResolver" --resource-group "exampleRG"

PowerShell

#Delete the inbound endpoint
Remove-AzDnsResolverInboundEndpoint -Name myinboundendpoint -DnsResolverName mydnsresolver -ResourceGroupName myresourcegroup

#Delete the virtual network link
Remove-AzDnsForwardingRulesetVirtualNetworkLink -DnsForwardingRulesetName $dnsForwardingRuleset.Name -Name vnetlink -ResourceGroupName myresourcegroup

#Delete the DNS forwarding ruleset
Remove-AzDnsForwardingRuleset -Name $dnsForwardingRuleset.Name -ResourceGroupName myresourcegroup

#Delete the outbound endpoint
Remove-AzDnsResolverOutboundEndpoint -DnsResolverName mydnsresolver -ResourceGroupName myresourcegroup -Name myoutboundendpoint

#Delete the DNS resolver
Remove-AzDnsResolver -Name mydnsresolver -ResourceGroupName myresourcegroup

Nästa steg

I den här snabbstarten skapade du ett virtuellt nätverk och en privat DNS-matchare. Konfigurera nu namnmatchning för Azure och lokala domäner.
