Packer構建無法SSH到AWS實例

Question

以下配置將啟動實例，但無法連接該實例...但是相同的密鑰，vpc-id，子網ID和安全組ID在測試廚房中可以正常工作。

{
  "variables": {
  "aws_access_key": "xxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "aws_secret_key": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
},
    "builders": [{
        "type": "amazon-ebs",
        "access_key": "{{user `aws_access_key`}}",
        "secret_key": "{{user `aws_secret_key`}}",
        "region": "us-east-1",
        "source_ami": "ami-146e2a7c",
        "instance_type": "t2.micro",
        "ssh_username": "ubuntu",
        "ami_name": "packer-example {{timestamp}}",
        "ssh_keypair_name": "xxx",
        "ssh_private_key_file": "xxx.pem",
        "vpc_id": "vpc-xxxxxxx",
        "subnet_id": "subnet-xxxxxxx",
        "security_group_id": "sg-xxxxxxx",
        "associate_public_ip_address": "true"

    }]
}

我收到以下調試錯誤：

2016/12/17 20:10:50 packer: 2016/12/17 20:10:50 [DEBUG] SSH handshake err: ssh: handshake failed: ssh: unable to authenticate, attempted methods [publickey none], no supported methods remain

鑒於這可以在沒有額外變量的測試廚房中正常工作，我想知道我缺少什么？ 有任何想法嗎？

Answer 1

問題是默認用戶名錯誤。

Answer 2

我通過忘記添加（aws帳戶的）public_key_pair來解決了這一問題，我收到了相同的錯誤消息“ amazon-ebs：等待SSH時出錯：ssh：握手失敗：ssh：無法驗證，嘗試的方法[none publickey]，仍然沒有受支持的方法”，問題是我忘記向dockerized Packer提供SSH_KEYPAIR_NAME。 添加kaypair名稱后，即可使用！
