在實例上設置 aws opsworks 時出現憑證錯誤

Question

我正在嘗試在 Ubuntu EC2 實例上設置 opsworks 以監控日志。 我正在向 Opsworks 注冊我的實例。 我得到的注冊命令是（插入 x 以保護信息）

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

但是，當我運行此命令時，安裝失敗並出現錯誤

/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)

這表明我沒有設置我的 aws 憑據，但我在 ~/.aws/credentials 中設置了我的 ACCESS_KEY_ID 和 SECRET_ACCESS_KEY，我也嘗試將這兩個變量導出為環境變量，但我仍然收到相同的錯誤。 知道為什么會發生這種情況嗎？

這是完整的 output

Answer 1

您可以查看此錯誤

/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)

這表明我沒有設置我的 aws 憑據，但我在 ~/.aws/credentials 中設置了我的ACCESS_KEY_ID和SECRET_ACCESS_KEY ，我也嘗試將這兩個變量導出為環境變量，但我仍然收到相同的錯誤。 知道為什么會發生這種情況嗎？

首先，在 AWS 中工作時不應該使用ACCESS_KEY_ID ，最好使用EC2 instance role 。

第二件事，這意味着上述密鑰沒有向 AWS opswork 堆棧注冊實例的權限。

您需要添加所需的權限才能在 ops 工作堆棧中添加實例。您可以使用以下權限使其工作。

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

使用 opswork 注冊的實例
