Prerequisites for deploying Azure Cloud Services (extended support)

  • Artikkeli

To help ensure a successful Azure Cloud Services (extended support) deployment, review the following steps. Complete each prerequisitive before you begin to create a deployment.

Required configuration file updates

Use the information in the following sections to make required updates to the configuration (.cscfg) file for your Cloud Services (extended support) deployment.

Virtual network

Cloud Services (extended support) deployments must be in a virtual network. You can create a virtual network by using the Azure portal, Azure PowerShell, the Azure CLI, or an Azure Resource Manager template (ARM template). The virtual network and subnets must be referenced in the NetworkConfiguration section of the configuration (.cscfg) file.

For a virtual network that is in the same resource group as the cloud service, referencing only the virtual network name in the configuration (.cscfg) file is sufficient. If the virtual network and Cloud Services (extended support) are in two different resource groups, specify the complete Azure Resource Manager ID of the virtual network in the configuration (.cscfg) file.

Note

If the virtual network and Cloud Services (extended support) are located in different resource groups, you can't use Visual Studio 2019 for your deployment. For this scenario, consider using an ARM template or the Azure portal to create your deployment.

Virtual network in the same resource group

<VirtualNetworkSite name="<vnet-name>"/> 
  <AddressAssignments> 
    <InstanceAddress roleName="<role-name>"> 
     <Subnets> 
       <Subnet name="<subnet-name>"/> 
     </Subnets> 
    </InstanceAddress> 
  </AddressAssignments>

Virtual network in a different resource group

<VirtualNetworkSite name="/subscriptions/<sub-id>/resourceGroups/<rg-name>/providers/Microsoft.Network/virtualNetworks/<vnet-name>"/> 
   <AddressAssignments> 
     <InstanceAddress roleName="<role-name>"> 
       <Subnets> 
        <Subnet name="<subnet-name>"/> 
       </Subnets> 
     </InstanceAddress> 
   </AddressAssignments>

Remove earlier versions of plugins

Remove earlier versions of remote desktop settings from the configuration (.cscfg) file:

<Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.Enabled" value="true" /> 
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountUsername" value="gachandw" /> 
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountEncryptedPassword" value="XXXX" /> 
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountExpiration" value="2021-12-17T23:59:59.0000000+05:30" /> 
<Setting name="Microsoft.WindowsAzure.Plugins.RemoteForwarder.Enabled" value="true" />

Remove earlier versions of diagnostics settings for each role in the configuration (.cscfg) file:

<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" />

Required definition file updates

Note

If you make changes to the definition (.csdef) file, you must generate the package (.cspkg or .zip) file again. Build and repackage your package (.cspkg or .zip) file after you make the following changes in the definition (.csdef) file to get the latest settings for your cloud service.

Virtual machine sizes

The following table lists deprecated virtual machine sizes and updated naming conventions through which you can continue to use the sizes.

The sizes listed in the left column of the table are deprecated in Azure Resource Manager. If you want to continue to use the virtual machine sizes, update the vmsize value to use the new naming convention from the right column.

Previous size name Updated size name
ExtraSmall Standard_A1_v2
Small Standard_A1_v2
Medium Standard_A2_v2
Large Standard_A4_v2
ExtraLarge Standard_A8_v2
A5 Standard_A2m_v2
A6 Standard_A4m_v2
A7 Standard_A8m_v2
A8 Deprecated
A9 Deprecated
A10 Deprecated
A11 Deprecated
MSODSG5 Deprecated

For example, <WorkerRole name="WorkerRole1" vmsize="Medium"> becomes <WorkerRole name="WorkerRole1" vmsize="Standard_A2">.

Note

To retrieve a list of available sizes, see the list of resource SKUs. Apply the following filters:

ResourceType = virtualMachines VMDeploymentTypes = PaaS

Remove earlier versions of remote desktop plugins

For deployments that use earlier versions of remote desktop plugins, remove the modules from the definition (.csdef) file and from any associated certificates:

<Imports> 
<Import moduleName="RemoteAccess" /> 
<Import moduleName="RemoteForwarder" /> 
</Imports>

For deployments that use earlier versions of diagnostics plugins, remove the settings for each role from the definition (.csdef) file:

<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" />

Access control

The subscription that contains networking resources must have the Network Contributor or greater role for Cloud Services (extended support). For more information, see RBAC built-in roles.

Key vault creation

Azure Key Vault stores certificates that are associated with Cloud Services (extended support). Add the certificates to a key vault, and then reference the certificate thumbprints in the configuration (.cscfg) file for your deployment. You also must enable the key vault access policy (in the portal) for Azure Virtual Machines for deployment so that the Cloud Services (extended support) resource can retrieve the certificate stored as secrets in the key vault. You can create a key vault in the Azure portal or by using PowerShell. You must create the key vault in the same region and subscription as the cloud service. For more information, see Use certificates with Cloud Services (extended support).
