快速入門:使用 Azure Container Registry 用戶端程式庫

使用此文章開始使用 Azure Container Registry 的用戶端程式庫。 請遵循下列步驟,在映像和成品上試用資料平面作業的範例程式碼。

使用 Azure Container Registry 的用戶端程式庫來:

  • 列出登錄中的映像或成品
  • 取得映像和成品、存放庫和標籤的中繼資料
  • 在登錄項目上設定讀取/寫入/刪除屬性
  • 刪除映像和成品、存放庫和標籤

Azure Container Registry 也有控制平面作業的管理程式庫,包括登錄建立和更新。

必要條件

重要概念

  • Azure 容器登錄會儲存容器映像OCI 成品
  • 映像或成品是由資訊清單圖層所組成。
  • 資訊清單描述構成映像或成品的圖層。 透過其摘要唯一識別。
  • 也可以標記映像或成品,以提供人類可讀取的別名。 映像或成品可以有零或多個與其相關聯的標籤,而且每個標籤可以唯一識別映像。
  • 共用相同名稱但具有不同標籤的映像或成品集合是存放庫

如需詳細資訊,請參閱關於登錄、存放庫和成品

開始使用

原始程式碼 | 套件 (NuGet) | API 參考 | 範例

若要開發可連線到 Azure Container Registry 執行個體的 .NET 應用程式程式碼,您需要 Azure.Containers.ContainerRegistry 程式庫。

Install the package

使用 NuGet 安裝適用於 .NET 的 Azure Container Registry 用戶端程式庫:

dotnet add package Azure.Containers.ContainerRegistry --prerelease

驗證用戶端

若要讓應用程式連線到您的登錄,您必須建立 ContainerRegistryClient,可以向其進行驗證。 使用 Azure 身分識別程式庫新增 Microsoft Entra ID 支援,以使用其對應的 Azure 服務來驗證 Azure SDK 用戶端。

當您在本機開發和偵錯應用程式時,您可以使用自己的使用者向登錄進行驗證。 完成此作業的其中一種方式是使用 Azure CLI 驗證使用者,並從此環境執行您的應用程式。 如果您的應用程式使用已建構的用戶端向 DefaultAzureCredential 進行驗證,會在指定的端點正確地向登錄進行驗證。

// Create a ContainerRegistryClient that will authenticate to your registry through Azure Active Directory
Uri endpoint = new Uri("https://myregistry.azurecr.io");
ContainerRegistryClient client = new ContainerRegistryClient(endpoint, new DefaultAzureCredential(),
    new ContainerRegistryClientOptions()
    {
        Audience = ContainerRegistryAudience.AzureResourceManagerPublicCloud
    });

如需在本機和部署環境中向 DefaultAzureCredential 進行驗證的詳細資訊,請參閱 Azure 身分識別讀我檔案。 若要連線到非公用 Azure 雲端中的登錄,請參閱 API 參考

如需有關搭配 Azure Container Registry 使用 Microsoft Entra ID 的詳細資訊,請參閱驗證概觀 (部分機器翻譯)。

範例

每個範例假設有一個 REGISTRY_ENDPOINT 環境變數設定為字串,其中包含 https:// 前置詞和登入伺服器的名稱,例如「https://myregistry.azurecr.io"」。

下列範例會使用傳回工作的非同步 API。 您也可以使用同步 API。

以非同步方式列出存放庫

逐一查看登錄中的存放庫集合。

// Get the service endpoint from the environment
Uri endpoint = new Uri(Environment.GetEnvironmentVariable("REGISTRY_ENDPOINT"));

// Create a new ContainerRegistryClient
ContainerRegistryClient client = new ContainerRegistryClient(endpoint, new DefaultAzureCredential(),
    new ContainerRegistryClientOptions()
    {
        Audience = ContainerRegistryAudience.AzureResourceManagerPublicCloud
    });

// Get the collection of repository names from the registry
AsyncPageable<string> repositories = client.GetRepositoryNamesAsync();
await foreach (string repository in repositories)
{
    Console.WriteLine(repository);
}

以非同步方式設定成品屬性

// Get the service endpoint from the environment
Uri endpoint = new Uri(Environment.GetEnvironmentVariable("REGISTRY_ENDPOINT"));

// Create a new ContainerRegistryClient
ContainerRegistryClient client = new ContainerRegistryClient(endpoint, new DefaultAzureCredential(),
    new ContainerRegistryClientOptions()
    {
        Audience = ContainerRegistryAudience.AzureResourceManagerPublicCloud
    });

// Get the collection of repository names from the registry
AsyncPageable<string> repositories = client.GetRepositoryNamesAsync();
await foreach (string repository in repositories)
{
    Console.WriteLine(repository);
}

以非同步方式刪除映像

using System.Linq;
using Azure.Containers.ContainerRegistry;
using Azure.Identity;

// Get the service endpoint from the environment
Uri endpoint = new Uri(Environment.GetEnvironmentVariable("REGISTRY_ENDPOINT"));

// Create a new ContainerRegistryClient
ContainerRegistryClient client = new ContainerRegistryClient(endpoint, new DefaultAzureCredential(),
    new ContainerRegistryClientOptions()
    {
        Audience = ContainerRegistryAudience.AzureResourceManagerPublicCloud
    });

// Iterate through repositories
AsyncPageable<string> repositoryNames = client.GetRepositoryNamesAsync();
await foreach (string repositoryName in repositoryNames)
{
    ContainerRepository repository = client.GetRepository(repositoryName);

    // Obtain the images ordered from newest to oldest
    AsyncPageable<ArtifactManifestProperties> imageManifests =
        repository.GetManifestPropertiesCollectionAsync(orderBy: ArtifactManifestOrderBy.LastUpdatedOnDescending);

    // Delete images older than the first three.
    await foreach (ArtifactManifestProperties imageManifest in imageManifests.Skip(3))
    {
        RegistryArtifact image = repository.GetArtifact(imageManifest.Digest);
        Console.WriteLine($"Deleting image with digest {imageManifest.Digest}.");
        Console.WriteLine($"   Deleting the following tags from the image: ");
        foreach (var tagName in imageManifest.Tags)
        {
            Console.WriteLine($"        {imageManifest.RepositoryName}:{tagName}");
            await image.DeleteTagAsync(tagName);
        }
        await image.DeleteAsync();
    }
}
