Packer-Powershell传递变量

如何解决Packer-Powershell传递变量

当前，我们成功在AWS域中使用打包程序（位于Azure DevOps中的构建管道中）部署映像。现在我们想更进一步，我们正在尝试为将来的Ansible维护配置几个用户。因此，我们编写了一个脚本并将其作为内联Powershell脚本进行了尝试，但是这两个选项似乎都无法使用Azure DevOps变量组中设置的变量，所有其他变量都已成功使用。我的代码如下：

{
"variables": {
    "build_version": "{{isotime \"2006.01.02.150405\"}}","aws_access_key": "$(aws_access_key)","aws_secret_key": "$(aws_secret_key)","region": "$(region)","vpc_id": "$(vpc_id)","subnet_id": "$(subnet_id)","security_group_id": "$(security_group_id)","VagrantUserpassword": "$(VagrantUserPassword)"
},"builders": [
    {
        "type": "amazon-ebs","access_key": "{{user `aws_access_key`}}","secret_key": "{{user `aws_secret_key`}}","region": "{{user `region`}}","vpc_id": "{{user `vpc_id`}}","subnet_id": "{{user `subnet_id`}}","security_group_id": "{{user `security_group_id`}}","source_ami_filter": {
            "filters": {
                "name": "Windows_Server-2016-English-Full-Base-*","root-device-type": "ebs","virtualization-type": "hvm"
            },"most_recent": true,"owners": [
                "801119661308"
            ]
        },"ami_name": "WIN2016-CUSTOM-{{user `build_version`}}","instance_type": "t3.xlarge","user_data_file": "userdata.ps1","associate_public_ip_address": true,"communicator": "winrm","winrm_username": "Administrator","winrm_timeout": "15m","winrm_use_ssl": true,"winrm_insecure": true,"ssh_interface": "private_ip"
    }
],"provisioners": [
        {
            "type": "powershell","environment_vars": ["VagrantUserPassword={{user `VagrantUserPassword`}}"],"inline": [
                "Install-WindowsFeature web-server,web-webserver,web-http-logging,web-stat-compression,web-dyn-compression,web-asp-net,web-mgmt-console,web-asp-net45","New-LocalUser -UserName 'Vagrant' -Description 'User is responsible for Ansible connection.' -Password '$(VagrantUserPassword)'"
            ]
        },{
            "type": "powershell","scripts": [
                "scripts/DisableUAC.ps1","scripts/iiscompression.ps1","scripts/ChocoPackages.ps1","scripts/PrepareAnsibleUser.ps1"
            ]
        },{
            "type": "windows-restart","restart_check_command": "powershell -command \"& {Write-Output 'Machine restarted.'}\""
        },"inline": [
                "C:\\ProgramData\\Amazon\\EC2-Windows\\Launch\\Scripts\\InitializeInstance.ps1 -Schedule","C:\\ProgramData\\Amazon\\EC2-Windows\\Launch\\Scripts\\SysprepInstance.ps1 -NoShutdown"
            ]
        }
    ]

}

“ VagrantUserpassword”：“ $（VagrantUserPassword）”不起作用，我们尝试了多个选项，但似乎都不起作用。

有什么主意吗？

亲切的问候，

解决方法

根据我的测试，管道变量确实无法传递给Powershell环境变量。

解决方法：

您可以尝试使用Replace Token task将管道值传递给Json文件。

以下是步骤：

1。在Json文件中设置值。

{
  "variables": {
....
  "VagrantUserpassword": "#{VagrantUserPassword}#"
},

1. 在脚本任务之前使用“替换令牌”任务。

1. 在管道变量中设置值。

然后可以成功设置该值。

另一方面，我还在您的示例文件中发现了一些问题。

1. “ environment_vars”：[“ VagrantUserPassword = {{用户VagrantUserPassword}}”]]，VagrantUserPassword需要替换为VagrantUserpassword（[“ VagrantUserPassword = {{用户{{ 1}}}}“]）。

注意：这是区分大小写的。

1. 您需要使用VagrantUserpassword来替换$Env:VagrantUserPassword

例如：

$(VagrantUserPassword)
