无法运行 GCP 打包程序实例上的 serverspec 测试

Question

我正在努力运行从本地机器对 GCP 打包程序实例进行 serverspec 测试。我创建了一个加壳器 json 配置文件，如下所示，以在 GCP 上创建图像：

{
"variables": {
    "project": "gcp-project",
    "image_family": "centos-7",
    "username": "centos",
    "zone": "us-central1-c",
    "version": "latest"
},

"builders": [
    {
        "type": "googlecompute",
        "account_file": "account.json",
        "project_id": "{{user `project`}}",
        "zone": "{{user `zone`}}",
        "source_image":"centos-7-v20171025",
        "image_name": "sftp-{{user `image_family`}}-{{user `version`}}-{{timestamp}}",
        "image_family": "{{user `image_family`}}",
        "image_description": "sftp - from packer",
        "ssh_username": "{{user `username`}}",
        "machine_type": "g1-small"
    }
],

"provisioners": [
    {
        "type": "shell-local",
        "command": "rake spec TARGET_HOST=remotehost"
    }
]

}

我正在从本地计算机执行 rake spec TARGET_HOST=(ip of packer instance) 到运行 serverspec 测试，并且 spec_helper.rb 配置了 ssh 登录，如下所示：

host = ENV['TARGET_HOST']
options = Net::SSH::Config.for(host)
options[:user] = 'centos'
set :host,        options[:host_name] || host
set :ssh_options, options

并且 Rakefile 配置为运行从特定文件夹进行测试。

在运行ning 打包程序构建命令之后 packer build -var-file=variables.json sftp.json| tee build.log

失败

Net::SSH::AuthenticationFailed:
Authentication failed for user centos@1.2.3.4

Packer 构建日志

    googlecompute:   end
    googlecompute: Net::SSH::AuthenticationFailed:
    googlecompute:   Authentication failed for user centos@1.2.3.4

由于这个错误，我无法运行在远程打包程序实例上使用 ssh 从本地计算机进行 serverspec 测试。

任何答案将不胜感激。非常感谢。

您似乎忘记了 centos 用户的密码。

将此添加到 spec_helper.rb：

options[:password] = ENV['LOGIN_PASSWORD']

并将您的 shell-local 调整为：

{
    "type": "shell-local",
    "command": "LOGIN_PASSWORD='{{ user `sftp_password` }}' rake spec TARGET_HOST=remotehost"
}
