使用 AWS SDK for .NET 的 Amazon ECS 示例

以下代码示例演示如何将 AWS SDK for .NET 与 Amazon ECS 结合使用来执行操作和实现常见场景。

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和跨服务示例的上下文查看操作。

场景是指显示如何通过在同一服务中调用多个函数来完成特定任务的代码示例。

每个示例都包含一个指向的链接 GitHub,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(); } } }
