Customize Azure resources

Bu içerik henüz dilinizde mevcut değil.

When working with Azure integrations in Aspire, you often need to customize the generated infrastructure beyond the default settings. Aspire provides two main approaches for customizing Azure resources: using the ConfigureInfrastructure API and creating custom Bicep templates.

Azure.Provisioning customization

The ConfigureInfrastructure API provides a strongly-typed, C#-based way to customize Azure resources. This is the recommended approach for most customizations.

Basic infrastructure customization

All Azure resources in Aspire inherit from AzureProvisioningResource, which exposes the ConfigureInfrastructure method:

var builder = DistributedApplication.CreateBuilder(args);

var storage = builder.AddAzureStorage("storage");

storage.ConfigureInfrastructure(infra =>
{
    // Get the storage account resource
    var storageAccount = infra.GetProvisionableResources()
                               .OfType<StorageAccount>()
                               .Single();

    // Customize the SKU
    storageAccount.Sku = new StorageSku
    {
        Name = StorageSkuName.PremiumLRS
    };

    // Add tags
    storageAccount.Tags["Environment"] = "Development";
    storageAccount.Tags["CostCenter"] = "Engineering";
});

Common customization scenarios

Configure SKUs and tiers

storage.ConfigureInfrastructure(infra =>
{
    var account = infra.GetProvisionableResources()
                       .OfType<StorageAccount>()
                       .Single();

    account.Sku = new StorageSku
    {
        Name = StorageSkuName.StandardGRS
    };
    account.Kind = StorageKind.StorageV2;
});

serviceBus.ConfigureInfrastructure(infra =>
{
    var ns = infra.GetProvisionableResources()
                  .OfType<ServiceBusNamespace>()
                  .Single();

    ns.Sku = new ServiceBusSku
    {
        Name = ServiceBusSkuName.Premium,
        Capacity = 2
    };
});

redis.ConfigureInfrastructure(infra =>
{
    var cache = infra.GetProvisionableResources()
                     .OfType<RedisCache>()
                     .Single();

    cache.Sku = new RedisCacheSku
    {
        Name = RedisCacheSkuName.Premium,
        Family = RedisCacheSkuFamily.P,
        Capacity = 1
    };
});

Configure networking

storage.ConfigureInfrastructure(infra =>
{
    var account = infra.GetProvisionableResources()
                       .OfType<StorageAccount>()
                       .Single();

    // Enable firewall
    account.NetworkRuleSet = new StorageAccountNetworkRuleSet
    {
        DefaultAction = StorageNetworkDefaultAction.Deny,
        Bypass = "AzureServices"
    };

    // Allow specific IP
    account.NetworkRuleSet.IpRules.Add(new StorageAccountIPRule
    {
        IPAddressOrRange = "203.0.113.0/24",
        Action = "Allow"
    });
});

Configure security and compliance

storage.ConfigureInfrastructure(infra =>
{
    var account = infra.GetProvisionableResources()
                       .OfType<StorageAccount>()
                       .Single();

    // Require HTTPS
    account.EnableHttpsTrafficOnly = true;

    // Configure TLS version
    account.MinimumTlsVersion = StorageMinimumTlsVersion.Tls1_2;

    // Enable blob encryption
    account.Encryption = new StorageAccountEncryption
    {
        KeySource = StorageAccountKeySource.MicrosoftStorage,
        Services = new StorageAccountEncryptionServices
        {
            Blob = new StorageEncryptionService { Enabled = true },
            File = new StorageEncryptionService { Enabled = true }
        }
    };
});

Working with multiple resources

When an integration creates multiple resources, you can customize each one:

var servicebus = builder.AddAzureServiceBus("messaging");
var queue = servicebus.AddQueue("orders");

servicebus.ConfigureInfrastructure(infra =>
{
    // Customize the namespace
    var ns = infra.GetProvisionableResources()
                  .OfType<ServiceBusNamespace>()
                  .Single();
    ns.Sku = new ServiceBusSku { Name = ServiceBusSkuName.Standard };

    // Customize the queue
    var queueResource = infra.GetProvisionableResources()
                             .OfType<ServiceBusQueue>()
                             .FirstOrDefault(q => q.Name.Contains("orders"));

    if (queueResource != null)
    {
        queueResource.MaxDeliveryCount = 5;
        queueResource.DefaultMessageTimeToLive = TimeSpan.FromHours(24);
    }
});

Adding Azure resources

You can add additional Azure resources to the infrastructure:

storage.ConfigureInfrastructure(infra =>
{
    // Add a private endpoint
    var privateEndpoint = new PrivateEndpoint("storagepe")
    {
        Location = "eastus",
        Subnet = new SubnetReference
        {
            Id = "/subscriptions/.../subnets/mysubnet"
        }
    };

    infra.Add(privateEndpoint);
});

Custom Bicep templates

For more complex scenarios or when you need full control, you can provide custom Bicep templates.

Using custom Bicep files

Create a custom Bicep file in your AppHost project:

@description('Storage account name')
param storageAccountName string

@description('Location')
param location string = resourceGroup().location

resource storageAccount 'Microsoft.Storage/storageAccounts@2023-01-01' = {
  name: storageAccountName
  location: location
  sku: {
    name: 'Premium_LRS'
  }
  kind: 'BlockBlobStorage'
  properties: {
    minimumTlsVersion: 'TLS1_2'
    allowBlobPublicAccess: false
    networkAcls: {
      defaultAction: 'Deny'
      bypass: 'AzureServices'
    }
  }
}

output connectionString string = 'DefaultEndpointsProtocol=https;AccountName=${storageAccount.name};...'

Reference it in your AppHost:

var builder = DistributedApplication.CreateBuilder(args);

var storage = builder.AddAzureBicepResource(
    name: "storage",
    bicepFilePath: "./custom-storage.bicep")
    .WithParameter("storageAccountName", "mystorageaccount");

builder.AddProject<Projects.WebApp>("webapp")
       .WithReference(storage);

Combining approaches

You can combine ConfigureInfrastructure with custom Bicep for maximum flexibility:

// Start with Aspire's default
var storage = builder.AddAzureStorage("storage");

// Customize with ConfigureInfrastructure
storage.ConfigureInfrastructure(infra =>
{
    var account = infra.GetProvisionableResources()
                       .OfType<StorageAccount>()
                       .Single();
    account.Sku = new StorageSku { Name = StorageSkuName.PremiumLRS };
});

// Add custom resources via Bicep
var customResource = builder.AddAzureBicepResource(
    name: "custom",
    bicepFilePath: "./custom-resource.bicep");

Best practices

Use ConfigureInfrastructure for standard customizations

For common property changes like SKUs, tags, and basic configuration, prefer ConfigureInfrastructure:

// ✅ Good - Simple and maintainable
storage.ConfigureInfrastructure(infra =>
{
    var account = infra.GetProvisionableResources()
                       .OfType<StorageAccount>()
                       .Single();
    account.Sku = new StorageSku { Name = StorageSkuName.PremiumLRS };
});

Use custom Bicep for complex scenarios

Use custom Bicep when you need:

Complex networking configurations
Multiple interconnected resources
Custom resource types not in Azure.Provisioning
Advanced policy configurations

Keep infrastructure code close to application code

Define infrastructure customizations in your AppHost alongside resource declarations:

// All storage configuration in one place
var storage = builder.AddAzureStorage("storage")
                     .ConfigureInfrastructure(infra =>
                     {
                         // Customizations here
                     });

Use configuration for environment-specific values

Don’t hard-code environment-specific values:

var skuName = builder.Configuration["Azure:Storage:Sku"] ?? "Standard_LRS";

storage.ConfigureInfrastructure(infra =>
{
    var account = infra.GetProvisionableResources()
                       .OfType<StorageAccount>()
                       .Single();
    account.Sku = new StorageSku { Name = skuName };
});

Generated Bicep inspection

After customization, you can inspect the generated Bicep:

Run your AppHost locally
Check the ./infra directory in your AppHost project
Review the generated .bicep files

The generated files reflect all customizations made via ConfigureInfrastructure.

Troubleshooting

Finding resource types

If you’re unsure what resource type to use:

storage.ConfigureInfrastructure(infra =>
{
    // List all resources
    var resources = infra.GetProvisionableResources();
    foreach (var resource in resources)
    {
        Console.WriteLine($"Type: {resource.GetType().Name}");
    }
});

Property not available

If a property isn’t available in the Azure.Provisioning types, you may need to:

Update to the latest Aspire version
Use custom Bicep for that specific property
File an issue on the Aspire GitHub repository

Validation errors

Azure will validate your configuration during deployment. Common issues:

Invalid SKU names or combinations
Location mismatches
Naming convention violations
Missing required properties
