AWS Opsworks 未能添加 EC2 实例答案

【问题标题】：AWS Opsworks failed to add EC2 instanceAWS Opsworks 未能添加 EC2 实例
【发布时间】：2020-04-11 20:57:19
【问题描述】：

我创建了新的 EC2 实例，并在 Opsworks 上创建了新层。我运行了一个显示在 Opsworks 面板上的命令，但它一直无法在 Opsworks 上注册。

命令

aws opsworks register --use-instance-profile --infrastructure-class ec2 --region us-east-1 --stack-id [stack id] --local

我在实例中运行命令时的错误日志

aws opsworks register --use-instance-profile --infrastructure-class ec2 --region us-east-1 --stack-id 50aebe6e-5aa1-4d2e-801c-b50ff1f22884 --local

Missing Credentials.

上面写着missing credentials，但我已经配置了凭据。 aws-cli 版本是

aws-cli/1.16.306 Python/2.7.6 Linux/3.13.0-137-generic botocore/1.13.42

另外，这个实例和其他实例不同，在不同的VPC中，所以我想知道是否只能注册同一VPC中的实例。

【问题讨论】：

这个运气好吗？你设法解决了这个问题吗？
@vargen_ 好吧，我无法解决问题。

【解决方案1】：

我遇到了同样的问题，但无法真正弄清楚原因。

还有另一种安装 OpsWorks 的方法，即在管理控制台中将角色附加到 EC2 实例，然后在实例上运行安装程序。这样就不用跑aws configure
