AWS目标组无法检测ECS的临时端口是因为ECS任务在启动时会随机分配一个临时端口，而目标组只能监听固定的端口。解决这个问题的方法是使用ECS Service Discovery。

下面是一个使用AWS CLI创建ECS任务和目标组，并解决临时端口问题的示例：

1. 创建ECS任务定义（task-definition.json）：

{
  "family": "my-task",
  "networkMode": "awsvpc",
  "containerDefinitions": [
    {
      "name": "my-container",
      "image": "my-image",
      "portMappings": [
        {
          "containerPort": 8080,
          "hostPort": 0,
          "protocol": "tcp"
        }
      ],
      "essential": true
    }
  ]
}

2. 创建ECS服务（service.json）：

{
  "cluster": "my-cluster",
  "serviceName": "my-service",
  "taskDefinition": "my-task",
  "launchType": "FARGATE",
  "networkConfiguration": {
    "awsvpcConfiguration": {
      "subnets": ["subnet-abc123"],
      "securityGroups": ["sg-abc123"],
      "assignPublicIp": "ENABLED"
    }
  }
}

3. 创建目标组（target-group.json）：

{
  "Name": "my-target-group",
  "Protocol": "HTTP",
  "Port": 80,
  "TargetType": "ip",
  "HealthCheckProtocol": "HTTP",
  "HealthCheckPort": "traffic-port",
  "HealthCheckPath": "/",
  "Matcher": {
    "HttpCode": "200"
  },
  "VpcId": "vpc-abc123"
}

4. 使用AWS CLI创建ECS任务和目标组：

# 创建ECS任务定义
aws ecs register-task-definition --cli-input-json file://task-definition.json

# 创建ECS服务
aws ecs create-service --cli-input-json file://service.json

# 创建目标组
aws elbv2 create-target-group --cli-input-json file://target-group.json

5. 更新ECS任务定义，使用Service Discovery：

{
  "family": "my-task",
  "networkMode": "awsvpc",
  "containerDefinitions": [
    {
      "name": "my-container",
      "image": "my-image",
      "portMappings": [
        {
          "containerPort": 8080,
          "hostPort": 0,
          "protocol": "tcp"
        }
      ],
      "essential": true,
      "logConfiguration": {
        "logDriver": "awslogs",
        "options": {
          "awslogs-group": "my-log-group",
          "awslogs-region": "us-west-2",
          "awslogs-stream-prefix": "my-container"
        }
      },
      "healthCheck": {
        "command": [
          "CMD-SHELL",
          "curl -f http://localhost:8080/ || exit 1"
        ],
        "interval": 30,
        "timeout": 5,
        "retries": 3
      },
      "secrets": [
        {
          "name": "DB_PASSWORD",
          "valueFrom": "arn:aws:ssm:us-west-2:1234567890:parameter/DB_PASSWORD"
        }
      ]
    }
  ],
  "serviceRegistries": [
    {
      "registryArn": "arn:aws:servicediscovery:us-west-2:1234567890:service/srv-abc123",
      "port": 8080,
      "containerPort": 8080
    }
  ]
}

6. 更新ECS服务，使用Service Discovery：

{
  "cluster": "my-cluster",
  "serviceName": "my-service",
  "taskDefinition": "my-task",
  "launchType": "FARGATE",
  "networkConfiguration": {
    "awsvpcConfiguration": {
      "subnets": ["subnet-abc123"],
      "securityGroups": ["sg-abc123"],
      "assignPublicIp": "ENABLED"
    }
  },
  "serviceRegistries": [
    {
      "registryArn": "arn:aws:servicediscovery:us-west-2:1234567890:service/srv-abc123",
      "port": 8080
    }
  ]
}

通过使用ECS Service Discovery，目标组将
