在没有公共IP的情况下将EC2实例注册到ECS集群 [英] Register EC2 instance to ECS cluster without public ip

问题描述

我很难将在VPC和专用子网（未连接互联网网关）上创建的实例添加到ECS群集。

I'm having hard times adding instances that are created in my VPC and on a private subnet(no internet gateway attached to it) to ECS cluster.

现在，我设法做到这一点的唯一方法是添加公共IP并配置了NAT实例/网关。

Right now the only way I've managed to do this was by adding a public IP and have a NAT instance/gateway configured.

如何将ECS群集与私有子网一起使用？

How do you use ECS clusters with private subnets?

推荐答案

我想我已经在AWS文档中找到了答案，似乎我需要使用NAT实例/网关：（

I guess I've found the answer on the AWS documentation and it seems I need to use a NAT instance/Gateway :(

另一个源以及官方文件

...容器实例需要外部网络访问权限才能与Amazon ECS服务终端节点进行通信，因此，如果您的容器实例运行在私有VPC中，则它们需要一个网络地址转换（NAT）实例来提供此访问权限。有关更多信息，请参阅NAT实例Amazon VPC用户指南。

"...Container instances need external network access to communicate with the Amazon ECS service endpoint, so if your container instances are running in a private VPC, they need a network address translation (NAT) instance to provide this access. For more information, see NAT Instances in the Amazon VPC User Guide."
