Question

此问题中的问题类似于SSH failed when building RancherOS with Packer

然而，我的Packer的行为是不同的。我得到了

==> virtualbox-iso: Error waiting for SSH: ssh: handshake failed: ssh:
unable to authenticate, attempted methods [none password keyboard-
interactive], no supported methods remain

我不确定为什么Packer无法进入虚拟机。我可以看到VirtualBox Console Screen位于登录输入上。然后它超时并被包装工的过程丢弃。

packer.json

      ]
   }
 ]
}

云config.yml

#cloud-config
rancher:
  ssh_authorized_keys:
    - ssh-rsa AAA ... some VALID RSA email@email.com
  network:
  interfaces:
    eth0:
      dhcp: true
    dns:
      nameservers:
        -8.8.8.8
        -8.8.4.4

编辑：在构建器中添加了这些行，并从供应商中删除了它们的等价物。这仍然无法解决我想要的其他步骤，但至少上传了cloud-config并且可以进行配置。

      "http_directory":"http",
      "boot_command":[
          "<esc><esc><enter><wait>",
          "wget http://{{ .HTTPIP }}:{{ .HTTPPort }}/cloud-config.yml <enter>",
          "sudo ros install -d /dev/sda -f -c cloud-config.yml -i rancher/os:{{ user `ros_version` }}",
          "<enter>"],

Answer 1

RancherOS默认情况下没有启用ssh密码。见issue #1467

这对我有用。
