使用亚马逊的ECS示例 Amazon SDK for .NET

以下代码示例向您展示如何在 Amazon 中使用来执行操作和实现常见场景ECS。 Amazon SDK for .NET

操作是大型程序的代码摘录,必须在上下文中运行。您可以通过操作了解如何调用单个服务函数,还可以通过函数相关场景的上下文查看操作。

场景是向您展示如何通过在一个服务中调用多个函数或与其他 Amazon Web Services 服务结合来完成特定任务的代码示例。

每个示例都包含一个指向完整源代码的链接,您可以在其中找到有关如何在上下文中设置和运行代码的说明。

using Amazon.ECS; using Amazon.ECS.Model; using Microsoft.Extensions.Hosting; namespace ECSActions; public class HelloECS { static async System.Threading.Tasks.Task Main(string[] args) { // Use the AWS .NET Core Setup package to set up dependency injection for the Amazon ECS domain registration service. // Use your AWS profile name, or leave it blank to use the default profile. using var host = Host.CreateDefaultBuilder(args).Build(); // Now the client is available for injection. var amazonECSClient = new AmazonECSClient(); // You can use await and any of the async methods to get a response. var response = await amazonECSClient.ListClustersAsync(new ListClustersRequest { }); Console.WriteLine($"Hello Amazon ECS! Following are some cluster ARNS available in the your aws account"); Console.WriteLine(); foreach (var arn in response.ClusterArns.Take(5)) { Console.WriteLine($"\tARN: {arn}"); Console.WriteLine($"Cluster Name: {arn.Split("/").Last()}"); Console.WriteLine(); } } }
