如何使用 ApplicationLoadBalancedFargateService cdk 构造为负载均衡器启用删除保护

Question

我使用 ApplicationLoadBalancedFargateService CDK 构造在应用程序负载均衡器前端的 ECS 集群上创建了 Fargate 服务 运行。

  cluster,
  memoryLimitMiB: 1024,
  desiredCount: 1,
  cpu: 512,
  taskImageOptions: {
    image: ecs.ContainerImage.fromRegistry("amazon/amazon-ecs-sample"),
  },
});

没有启用删除保护的道具。谁能说说他的经历？

CDK 提供 Escape Hatches 功能以在任何 High-level 构造没有参数的情况下使用 Clouformation Props。

// Create a load-balanced Fargate service and make it public
    var loadBalancedService = new ecs_patterns.ApplicationLoadBalancedFargateService(this, `${ENV_NAME}-pgadmin4`, {
      cluster: cluster, // Required
      cpu: 512, // Default is 256
      desiredCount: 1, // Default is 1
      taskImageOptions: { 
        image: ecs.ContainerImage.fromRegistry('image'),
        environment: {}
        },
      memoryLimitMiB: 1024, // Default is 512
      assignPublicIp: true
    });
  
    // Get the CloudFormation resource
    const cfnLB = loadBalancedService.loadBalancer.node.defaultChild as elbv2.CfnLoadBalancer;
    cfnLB.loadBalancerAttributes = [{
      key: 'deletion_protection.enabled',
      value: 'true',
    },
   ];
