Azure Resource Manager Redis Dotnet

Azure.ResourceManager.Redis (.NET)

Management plane SDK for provisioning and managing Azure Cache for Redis resources via Azure Resource Manager.

⚠️ Management vs Data Plane

• This SDK (Azure.ResourceManager.Redis): Create caches, configure firewall rules, manage access keys, set up geo-replication
• Data Plane SDK (StackExchange.Redis): Get/set keys, pub/sub, streams, Lua scripts

Installation

dotnet add package Azure.ResourceManager.Redis
dotnet add package Azure.Identity

Current Version: 1.5.1 (Stable)
API Version: 2024-11-01
Target Frameworks: .NET 8.0, .NET Standard 2.0

Environment Variables

AZURE_SUBSCRIPTION_ID=<your-subscription-id>
# For service principal auth (optional)
AZURE_TENANT_ID=<tenant-id>
AZURE_CLIENT_ID=<client-id>
AZURE_CLIENT_SECRET=<client-secret>

Authentication

using Azure.Identity;
using Azure.ResourceManager;
using Azure.ResourceManager.Redis;

// Always use DefaultAzureCredential
var credential = new DefaultAzureCredential();
var armClient = new ArmClient(credential);

// Get subscription
var subscriptionId = Environment.GetEnvironmentVariable("AZURE_SUBSCRIPTION_ID");
var subscription = armClient.GetSubscriptionResource(
    new ResourceIdentifier($"/subscriptions/{subscriptionId}"));

Core Workflows

1. Create Redis Cache

using Azure.ResourceManager.Redis;
using Azure.ResourceManager.Redis.Models;

// Get resource group
var resourceGroup = await subscription
    .GetResourceGroupAsync("my-resource-group");

// Define cache configuration
var cacheData = new RedisCreateOrUpdateContent(
    location: AzureLocation.EastUS,
    sku: new RedisSku(RedisSkuName.Standard, RedisSkuFamily.BasicOrStandard, 1))
{
    EnableNonSslPort = false,
    MinimumTlsVersion = RedisTlsVersion.Tls1_2,
    RedisConfiguration = new RedisCommonConfiguration
    {
        MaxMemoryPolicy = "volatile-lru"
    },
    Tags =
    {
        ["environment"] = "production"
    }
};

// Create cache (long-running operation)
var cacheCollection = resourceGroup.Value.GetAllRedis();
var operation = await cacheCollection.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "my-redis-cache",
    cacheData);

RedisResource cache = operation.Value;
Console.WriteLine($"Cache created: {cache.Data.HostName}");

2. Get Redis Cache

// Get existing cache
var cache = await resourceGroup.Value
    .GetRedisAsync("my-redis-cache");

Console.WriteLine($"Host: {cache.Value.Data.HostName}");
Console.WriteLine($"Port: {cache.Value.Data.Port}");
Console.WriteLine($"SSL Port: {cache.Value.Data.SslPort}");
Console.WriteLine($"Provisioning State: {cache.Value.Data.ProvisioningState}");

3. Update Redis Cache

var patchData = new RedisPatch
{
    Sku = new RedisSku(RedisSkuName.Standard, RedisSkuFamily.BasicOrStandard, 2),
    RedisConfiguration = new RedisCommonConfiguration
    {
        MaxMemoryPolicy = "allkeys-lru"
    }
};

var updateOperation = await cache.Value.UpdateAsync(
    WaitUntil.Completed,
    patchData);

4. Delete Redis Cache

await cache.Value.DeleteAsync(WaitUntil.Completed);

5. Get Access Keys

var keys = await cache.Value.GetKeysAsync();
Console.WriteLine($"Primary Key: {keys.Value.PrimaryKey}");
Console.WriteLine($"Secondary Key: {keys.Value.SecondaryKey}");

6. Regenerate Access Keys

var regenerateContent = new RedisRegenerateKeyContent(RedisRegenerateKeyType.Primary);
var newKeys = await cache.Value.RegenerateKeyAsync(regenerateContent);
Console.WriteLine($"New Primary Key: {newKeys.Value.PrimaryKey}");

7. Manage Firewall Rules

// Create firewall rule
var firewallData = new RedisFirewallRuleData(
    startIP: System.Net.IPAddress.Parse("10.0.0.1"),
    endIP: System.Net.IPAddress.Parse("10.0.0.255"));

var firewallCollection = cache.Value.GetRedisFirewallRules();
var firewallOperation = await firewallCollection.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "allow-internal-network",
    firewallData);

// List all firewall rules
await foreach (var rule in firewallCollection.GetAllAsync())
{
    Console.WriteLine($"Rule: {rule.Data.Name} ({rule.Data.StartIP} - {rule.Data.EndIP})");
}

// Delete firewall rule
var ruleToDelete = await firewallCollection.GetAsync("allow-internal-network");
await ruleToDelete.Value.DeleteAsync(WaitUntil.Completed);

8. Configure Patch Schedule (Premium SKU)

// Patch schedules require Premium SKU
var scheduleData = new RedisPatchScheduleData(
    new[]
    {
        new RedisPatchScheduleSet
