AWS Opsworks未能添加EC2实例。

Question

我制作了新的EC2实例，并在Opsworks上创建了新的层。我运行了一个命令，显示在Opsworks面板上，但它一直不能在Opsworks上注册。

命令如下

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

当我在实例中运行命令时的错误记录

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

Missing Credentials.

它说 missing credentials但我已经配置了证书。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，是在不同的VPC，不知道是不是只有在同一个VPC的实例才能注册。

Answer 1

我也遇到了非常相同的问题，但实在想不出原因。

不过还有一种安装OpsWorks的方法，就是在管理控制台中给EC2实例附加一个角色，然后在实例上运行安装程序。这样一来，就不需要运行 aws configure
