在实例上设置 aws opsworks 的凭据错误

Question

我正在尝试在 Ubuntu EC2 实例上设置 opsworks 以监控日志。我正在向 Opsworks 注册我的实例。我得到的注册命令是（插入 x 以保护信息）

aws opsworks register --use-instance-profile --infrastructure-class ec2 --region xx-west-xx --stack-id xxxxxxx-fe9c-xxxxx-99f8-xxxxxxx --local

但是当我运行这个命令时安装失败并出现错误

/opt/aws/opsworks/local/lib/ruby/gems/2.2.0/gems/aws-sdk-core-2.2.26/lib/aws-sdk-core/plugins/request_signer.rb:100:in `require_credentials': unable to sign request without credentials set (Aws::Errors::MissingCredentialsError)

这表明我没有设置我的 aws 凭据，但我在 ~/.aws/credentials 中同时设置了 ACCESS_KEY_ID 和 SECRET_ACCESS_KEY，我也尝试过导出两者这些变量作为环境变量，但我仍然收到相同的错误。知道为什么会这样吗？

这是完整的输出

你可以查看这个错误

/opt/aws/opsworks/local/lib/ruby/gems/2.2.0/gems/aws-sdk-core-2.2.26/lib/aws-sdk-core/plugins/request_signer.rb:100:in `require_credentials': unable to sign request without credentials set (Aws::Errors::MissingCredentialsError)

This would suggest I do not have my aws credentials set, but I have both my ACCESS_KEY_ID and SECRET_ACCESS_KEY set in ~/.aws/credentials, I have also tried exporting both of these variables as environment variables but I still receive the same error. Any idea why this could be happening?

首先，您在 AWS 中工作时不应使用 ACCESS_KEY_ID，最好使用 EC2 instance role。

其次，这意味着上述密钥没有向 AWS opswork 堆栈注册实例的权限。

您需要添加所需的权限才能在 ops 工作中添加实例 stack.you 可以使用以下权限使其工作。

{
      "Version": "2012-10-17",
      "Statement": [
        {
          "Effect": "Allow",
          "Action": [
            "opsworks:RegisterInstance", 
            "opsworks:DeregisterInstance",
            "opsworks:DescribeInstances"
          ],
          "Resource": [
            "*"
          ]
        }
      ]
    }
