Register Azure Local with Azure Arc using Arc gateway

Prerequisites

• You have access to Azure Local machines running release 2506 or later. Earlier versions don't support this scenario.

• You have assigned the appropriate permissions to the subscription used for registration. For more information, see Assign required permissions for Azure Local deployment.

• An Arc gateway resource is created in the same subscription used to deploy Azure Local. For more information, see Create the Arc gateway resource in Azure.

• You have reviewed the supported and unsupported scenarios. For more information, see Supported and unsupported scenarios.

• Required endpoints are open in your firewall. For more information, see Azure Local endpoints not redirected.

• Review guidance on handling preinstalled or outdated OS images during Azure Arc registration.

Step 1: Get the Arc gateway ID

• Get Arc gateway ID. To create Azure Arc gateway, see Set up an Azure Arc gateway and get the resource ID of the Arc gateway. This is also referred to as the ArcGatewayID.

  1. In the Azure portal, go to the Arc gateway resource that you created.
  2. On the Overview page, copy the Resource ID. You use this Arc gateway ID later.

  

Step 2: Set parameters

1. Set the parameters required for the registration script.

   Here's an example of how you should change these parameters for the Invoke-AzStackHciArcInitialization initialization script.

   #Define the tenant you will use to register your machine as Arc device
   $Tenant = "YourTenantID"
   
   #Define the subscription where you want to register your Azure Local machine with Arc.
   $Subscription = "yourSubscriptionID" 
   
   #Define the resource group where you want to register your Azure Local machine with Arc.
   $RG = "yourResourceGroupName" 
   
   #Define the region to use to register your server as Arc device
   #Do not use spaces or capital letters when defining region
   $Region = "eastus"
   
   #Define the proxy address for your Azure Local deployment to access the internet via proxy.
   $ProxyServer = "http://proxyaddress:port"    
   
   #Define the bypass list for the proxy. Use comma to separate each item from the list.  
   # Parameters must be separated with a comma `,`.
   # Use "localhost" instead of <local> 
   # Use specific IPs such as 127.0.0.1 without mask 
   # Use * for subnets allowlisting. 192.168.1.* for /24 exclusions. Use 192.168.*.* for /16 exclusions. 
   # Append * for domain names exclusions like *.contoso.com 
   # DO NOT INCLUDE .svc on the list. The registration script takes care of Environment Variables configuration. 
   # At least the IP address of each Azure Local machine.
   # At least the IP address of the Azure Local cluster.
   # At least the IPs you defined for your infrastructure network. Arc resource bridge, Azure Kubernetes Service (AKS), and future infrastructure services using these IPs require outbound connectivity.
   # NetBIOS name of each machine.
   # NetBIOS name of the Azure Local cluster.
   
   $ProxyBypassList = "localhost,127.0.0.1,*.contoso.com,machine1,machine2,machine3,machine4,machine5,192.168.*.*,AzureLocal-1" 
   
   #Define the Arc gateway resource ID from Azure 
   $ArcgwId = "/subscriptions/yourarcgatewayid/resourceGroups/yourResourceGroupName/providers/Microsoft.HybridCompute/gateways/yourArcGatewayName" 
   
   # Define the target Azure Local solution version that the node must update to after registering with Azure Arc.
   # Example: "12.2602.1002.10"
   $TargetSolutionVersion = "<solution-version>" 
   
   

Step 3: Run registration script

1. Run the Arc registration script. The script takes a few minutes to run.

   #Invoke the registration script with Proxy and ArcgatewayID 
   Invoke-AzStackHciArcInitialization -TenantID $Tenant -SubscriptionID $Subscription -ResourceGroup $RG -Region $Region -Cloud "AzureCloud" -Proxy $ProxyServer -ArcGatewayID $ArcgwId -ProxyBypass $ProxyBypassList -TargetSolutionVersion $TargetSolutionVersion
   

2. During the Arc registration process, you must authenticate with your Azure account. The console window displays a code that you must enter in the URL, displayed in the app, in order to authenticate. Follow the instructions to complete the authentication process.

   

Handle preinstalled or outdated OS images during Azure Arc registration

During Azure Arc registration, Azure Local verifies whether the OS image is current for its release baseline. If the image is outdated or unsupported, the system automatically updates it during registration. You can optionally specify a target solution version using the TargetSolutionVersion parameter.

• The update typically takes 40-45 minutes.

• A system reboot is required.

• During the update, the registration status appears as Update: InProgress.

  

Monitor and complete registration

1. If registration times out or the machine reboots, reconnect and check the registration progress using the following commands:

   $status = Get-ArcBootstrapStatus
   $status.Response.Status
   

2. Review the status value:

   • Succeeded: Registration completed successfully after the update.
   • Failed: Rerun registration using a new ARM token or device code flow.
   • If the issue persists, collect logs using Collect-ArcBootstrapSupportLogs and share them for further troubleshooting.

3. After the reboot, rerun the Invoke-AzStackHciArcInitialization cmdlet to continue.

Step 4: Verify the Azure Arc gateway setup is successful

Once the registration is complete, follow these steps to verify that Azure Arc gateway setup is successful.

1. Connect to the first Azure Local machine from your system.

2. Open the Arc gateway log to monitor which endpoints are being redirected to the Arc gateway and which ones continue using your firewall or proxy. You can find the Arc gateway log at: c:\programdata\AzureConnectedMAchineAgent\Log\arcproxy.log.

   

3. To check the Arc agent configuration and verify that it's using the gateway, run the following command:

   C:\program files\AzureConnectedMachineAgent>.\azcmagent show
   

   The values displayed should be as follows:

   1. Agent version is 1.45 or later.

   2. Agent Status should show as Connected.

   3. Using HTTPS Proxy shows as http://localhost:40343when the Arc gateway is enabled.

   4. Upstream Proxy shows your enterprise proxy server and port.

   5. Azure Arc Proxy shows as running when the Arc gateway is enabled.

   

4. Additionally, to verify that the setup was done successfully, run the following command:

   C:\program files\AzureConnectedMachineAgent>.\azcmagent check
   

   The response should indicate that the connection.type is set to gateway, and the Reachable column should indicate true for all URLs.

   Here's an example of the Arc agent using the Arc gateway:

   

   You can also audit your gateway traffic by viewing the gateway router logs.

   To view gateway router logs on Windows, run the azcmagent logs command in PowerShell. In the resulting .zip file, the logs are located in the C:\ProgramData\Microsoft\ArcGatewayRouter folder.

If you plan to deploy a few machines per site, use the Configurator app to register your Azure Local machines with Azure Arc.
