如何使用 Packer vSphere-ISO HCL2JSON 语法映射网络适配器和存储块

如何解决如何使用 Packer vSphere-ISO HCL2JSON 语法映射网络适配器和存储块

我正在尝试使用 HCL2 JSON 语法构建 VM。如果这是不可能的，这不是交易破坏者。我只是更喜欢使用 JSON 语法，因为我发现以编程方式操作更容易、更清晰。我不断遇到添加存储和网络适配器复杂类型的问题。我相信这两个关键字都是 list(map(string)) 类型。这是我目前拥有的：

var-defs.pkr.json：

{
    "variable": {
        "network_adapters": {
            "description": "List of network adapters to add to the VM.","type": "list(object({ network=string,network_card=string }))","default": [
                {
                    "network": "Infra","network_card": "vmxnet3"
                }
            ]
        },"storage": {
            "description": "List of virtual disks to add to the VM.","type": "list(object({ disk_controller_index=number,disk_size=number,disk_thin_provisioned=bool }))","default": [
                {
                    "disk_controller_index": 0,"disk_size": 65536,"disk_thin_provisioned": true
                }
            ]
        }
    }
}

我也尝试将类型设置为 "list(map(string))"。

var.auto.pkrvars.json：

{
    "network_adapters" : [
        {
            "network": "Infra","network_card": "vmxnet3"
        }
    ],"storage" : [
        {
            "disk_controller_index" : 0,"disk_size" : 65536,"disk_thin_provisioned" : true
        },{
            "disk_controller_index" : 0,"disk_thin_provisioned" : true
        }
    ]
}

我尝试了以下方法但没有成功：

source.pkr.json（直接赋值）：

{
    "source" : {
        "vsphere-iso" : {
            "hcl2-json-build-vm" : {
                "network_adapters" : "${var.network_adapters}","storage" : "${var.storage}"
            }
        }
    }
}

source.pkr.json（乱码）：

{
    "source" : {
        "vsphere-iso" : {
            "hcl2-json-build-vm" : {
                "network_adapters" : [
                    {
                        "network" : "${var.network_adapters[*].network}","network_card" : "${var.network_adapters[*].network_card}"
                    }
                ],"storage" : [
                    {
                        "disk_controller_index" : "${var.storage[*].disk_controller_index}","disk_size" : "${var.storage[*].disk_size}","disk_thin_provisioned" : "${var.storage[*].disk_thin_provisioned}"
                    }
                ]
            }
        }
    }
}

source.pkr.json（动态块）：

{
    "source" : {
        "vsphere-iso" : {
            "hcl2-json-build-vm" : {
                "dynamic" : {
                    "network_adapters" : {
                        "for_each" : "${var.network_adapters}","content"  : {
                            "network" : "${network_adapters.network}","network_card" : "${network_adapters.network_card}"
                        }
                    },"storage" : {
                        "for_each" : "${var.storage}","content"  : {
                            "disk_controller_index" : "${storage.disk_controller_index}","disk_size" : "${storage.disk_size}","disk_thin_provisioned" : "${storage.disk_thin_provisioned}"
                        }
                    }
                }
            }
        }
    }
}

谁能帮我指出我的错误，或者让我知道目前这是否可行？非常感谢！

编辑： 为了更好地记录（并给线程一个颠簸，老实说）我在尝试在用户变量中定义 network_adapters 和存储并使用 splatting 方法时遇到的错误是：

Error: Incorrect attribute value type
  on source.pkr.json line 39:
  (source code not available)

字符串插值似乎没有按预期工作。我做错了吗？

解决方法

稍加修改后，我让 SwampDragons here 提出的建议生效。最终实现看起来像这样，以防将来有人遇到同样的问题：
