amazon-web-services - 如何使用 CloudFormation 设置 EC2 实例连接？

Question

我正在尝试为 EC2 实例设置 EC2 Instance Connect：

AWSTemplateFormatVersion: 2010-09-09
Description: Part 1 - Spawn Ec2 instance with CloudFormation

Resources:
  WebAppInstance:
    Type: AWS::EC2::Instance
    Properties:
      AvailabilityZone: us-east-2a
      ImageId: ami-074cce78125f09d61
      InstanceType: t2.micro

尽管上面的模板允许我创建一个 EC2 实例，但它不允许我使用 EC2 Instance Connect 访问它。

如何在 CloudFormation 模板中配置 EC2 Instance Connect？

Answer 1

OnAmazon Linux 2 (any version)并且Ubuntu 16.04 or laterEC2 Instance Connect 已安装并 默认运行。所以你不必做任何事情。

对于其他 AMI，您必须使用 user_data自行安装和设置 连接。
