AppHost 无法在容器内工作，因为它需要能够与 Docker/Podman 通信来创建共享资源。

例如，如果您添加 Redis 作为 Aspire 组件（在 API 和 Web 前端之间共享），如果该组件已经在容器内运行，AppHost 将如何在容器中创建该组件？

我查看了您的堆栈跟踪，并注意到一些提示，表明 Aspire 正在尝试创建容器/k8s 集群。

在/

/src/Aspire.Hosting/Dcp/KubernetesService.cs中的Aspire.Hosting.Dcp.KubernetesService.ExecuteWithRetry [TResult]（DcpApiOperationType操作类型，字符串资源类型，Func
2 operation, CancellationToken cancellationToken) in /_/src/Aspire.Hosting/Dcp/KubernetesService.cs:line 198 at Aspire.Hosting.Dcp.KubernetesService.ExecuteWithRetry[TResult](DcpApiOperationType operationType, String resourceType, Func2操作，CancellationToken取消令牌）：第205行 在 //src/Aspire.Hosting/Dcp/ApplicationExecutor.cs 中的 Aspire.Hosting.Dcp.ApplicationExecutor.CreateResourcesAsync[RT](CancellationToken CancellationToken)：第 683 行 在 //src/Aspire.Hosting/Dcp/ApplicationExecutor.cs 中的 Aspire.Hosting.Dcp.ApplicationExecutor.CreateServicesAsync(CancellationToken CancellationToken)：第 124 行 在 //src/Aspire.Hosting/Dcp/ApplicationExecutor.cs 中的 Aspire.Hosting.Dcp.ApplicationExecutor.RunApplicationAsync(CancellationToken CancellationToken)：第 81 行 在 /_/src/Aspire.Hosting/Dcp/DcpHostService.cs 中的 Aspire.Hosting.Dcp.DcpHostService.StartAsync(CancellationToken CancellationToken)：第 83 行 在 Microsoft.Extensions.Hosting.Internal.Host.b__15_1（IHostedService 服务，CancellationToken 令牌） 在 Microsoft.Extensions.Hosting.Internal.Host.ForeachService[T]（IEnumerable
1 services, CancellationToken token, Boolean concurrent, Boolean abortOnFirstException, List
1 个例外，Func`3 操作）

我不确定这是否可行，因为 Aspire 始终需要容器主机外部的编排器来创建这些容器。 asAppHost 已经是那个协调器，创建另一个供 AppHost 与之对话就意味着创建一个不必要的中间人。
