多容器 Azure WebApp 无法与托管身份一起使用

Multicontainer Azure WebApp not working with Managed Identity

Scenario/repro

我有多容器(教程 here)Azure Web 应用程序。我将系统分配的标识分配给了我的网络应用程序。我的 docker compose 中有两个容器:

一切正常(我的 API 正在使用防病毒软件扫描文件),直到我为 Azure 资源添加具有托管身份的密钥保管库配置提供程序 (link)。这与我在 linux.

上的标准 Web 应用程序完美配合
// Program.cs
.ConfigureAppConfiguration((context, config) =>
{
  if (context.HostingEnvironment.IsProduction())
  {
    var builtConfig = config.Build();
    var secretClient = new SecretClient(new Uri($"https://{builtConfig["KeyVaultName"]}.vault.azure.net/"),
    new DefaultAzureCredential());
    config.AddAzureKeyVault(secretClient, new KeyVaultSecretManager());
  }
})

问题 我的 API returns 503 状态码。 看来我需要做一些额外的配置才能使其与 Docker compose 一起使用。

似乎不​​完全支持此功能。知道如何在这种情况下使用密钥保管库提供商吗?
