我正在尝试为AWS EKS托管节点组构建自定义映像，注意：我的自定义映像(ubuntu(已经启用了MFA和基于私钥的身份验证。
我从下面的url克隆了github存储库来构建与eks相关的更改。
git clone https://github.com/awslabs/amazon-eks-ami && cd amazon-eks-ami
接下来，我做了一些更改来运行make文件
cat eks-worker-al2.json

添加用户和私钥后，生成失败，出现以下错误。
记录
amazon-ebs: Error waiting for SSH: Packer experienced an authentication error when trying to connect via SSH. This can happen if your username/password are wrong. You may want to double-check your credentials as part of your debugging process. original error: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain.
对我来说，只需更改aws的区域，就可以删除packer中的aws区域。
