AWS ECS / FARGATE-服务任务正在运行，但没有容器实例

Question

我正在尝试使用ECS / FARGATE将具有API的docker容器映像部署到AWS上，并且服务任务似乎似乎正在运行时，它没有容器实例关联，因此我无法与我的API通信。一般来说，我对AWS的经验不是很丰富，所以如果我犯了一个菜鸟错误，我会提前道歉。

我尝试过的

1. 创建了ECR，推送了我的docker映像
2. 创建集群
3. 创建任务定义：

1. 使用任务定义创建服务。还将它连接到我的应用程序负载平衡器。

2. 在EC2中，我添加了一个新的ecs-optimized实例，并通过执行以下操作将其连接到集群： ECS_CLUSTER=my-cluster >> /etc/ecs/ecs.config来自实例内部。

3. 我从服务运行任务。

结果

• 我从任务日志中看到正在运行的应用程序：

但是我无法从计算机上的curl得到任何答复。我正在尝试将请求发送到我的负载均衡器，甚至发送到任务提供的公共IP 地址：

• 从集群视图中，我看到正在运行的任务，其中没有容器实例：

• 在“ ECS实例”任务中，我看到分配有没有正在运行的任务的EC2：

• 运行状况检查似乎失败，因为任务每隔几分钟停止并重新启动。

我已关注此问题的多个教程，但似乎都没有解决该问题的方法。欢迎提供任何提示，如果缺少某些信息，我会很乐意添加。
