【问题描述】：
我正在一个模块上尝试新的for_each 函数，它本身会输出一些我需要传递给另一个资源的值。
module "vnets" {
source = "../caf-virtual-network"
for_each = var.vnet_list
ARM_ENVIRONMENT = var.ARM_ENVIRONMENT
ARM_LOCATION = var.ARM_LOCATION
ARM_SUBSCRIPTION_ID = var.ARM_SUBSCRIPTION_ID
diagnostics_map = local.diagnostics_map
location = var.ARM_LOCATION
netwatcher = local.netwatcher
networking_object = each.value
tags = var.global_settings.tags
virtual_network_rg = "${module.names.standard["resource-group"]}-${each.value.vnet.resource_group_name}"
depends_on = [
module.resource_groups_networking
]
}
我可以通过指定类似这样的内容来获取一个或多个对象的模块输出
output "subnets" { value = module.vnets["vnet_shared_services_object"].vnet_subnets } ，它又看起来像这样：
"vnet_shared_services_object" = {
"sn-dev-uks-asdf-app-dynamic" = "/subscriptions/asdf/resourceGroups/asdf/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-shared-services/subnets/sn-dev-uks-asdf-app-dynamic"
"sn-dev-uks-asdf-artifactory" = "/subscriptions/asdf/resourceGroups/asdf/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-shared-services/subnets/sn-dev-uks-asdf-artifactory"
}
这里我指定了 ONE 对象的输出，但我想一键动态指定两个对象的输出。
所以我想要这个；
"vnet_shared_services_object" = {
"sn-dev-uks-asdf-app-dynamic" = "/subscriptions/asdf/resourceGroups/asdf/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-shared-services/subnets/sn-dev-uks-asdf-app-dynamic"
"sn-dev-uks-asdf-artifactory" = "/subscriptions/asdf/resourceGroups/asdf/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-shared-services/subnets/sn-dev-uks-asdf-artifactory"
}
"vnet_transit_object" = {
"AzureFirewallSubnet" = "/subscriptions/asdf/resourceGroups/qwer/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-transit/subnets/AzureFirewallSubnet"
"GatewaySubnet" = "/subscriptions/asdf/resourceGroups/qwer/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-transit/subnets/GatewaySubnet"
"sn-dev-uks-asdf-bind-dns" = "/subscriptions/asdf/resourceGroups/qwer/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-transit/subnets/sn-dev-uks-asdf-bind-dns"
}
...输出如下所示：
subnets = {
"sn-dev-uks-asdf-app-dynamic" = "/subscriptions/asdf/resourceGroups/asdf/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-shared-services/subnets/sn-dev-uks-asdf-app-dynamic"
"sn-dev-uks-asdf-artifactory" = "/subscriptions/asdf/resourceGroups/asdf/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-shared-services/subnets/sn-dev-uks-asdf-artifactory"
"AzureFirewallSubnet" = "/subscriptions/asdf/resourceGroups/qwer/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-transit/subnets/AzureFirewallSubnet"
"GatewaySubnet" = "/subscriptions/asdf/resourceGroups/qwer/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-transit/subnets/GatewaySubnet"
"sn-dev-uks-asdf-bind-dns" = "/subscriptions/asdf/resourceGroups/qwer/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-transit/subnets/sn-dev-uks-asdf-bind-dns"
}
所以我知道执行以下操作会起作用，但我想说的是我不知道要生成多少个 vnet 模块，因此我需要使这个动态化：
output merge{
value = merge({
for key, value in module.vnets["vnet_shared_services_object"].vnet_subnets:
key => value
},
{
for key, value in module.vnets["vnet_transit_object"].vnet_subnets:
key => value
})
}
使用 Terraform 上的指南来展平 (https://www.terraform.io/docs/configuration/functions/flatten.html) 输出对象有效，但这不是我希望的那样：
output stuff {
value = flatten([
for key, value in module.vnets: [
for subnet, id in value.vnet_subnets: {
"${subnet}" = id
}
]
])
}
...等同于：
stuff = [
{
"sn-dev-uks-asdf-app-dynamic" = "/subscriptions/asdf/resourceGroups/rg-dev-uks-asdf-vnet-shared-services/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-shared-services/subnets/sn-dev-uks-asdf-app-dynamic"
},
{
"sn-dev-uks-asdf-artifactory" = "/subscriptions/asdf/resourceGroups/rg-dev-uks-asdf-vnet-shared-services/providers/Microsoft.Network/virtualNetworks/vnet-dev-uks-asdf-shared-services/subnets/sn-dev-uks-asdf-artifactory"
},
...and so on
]
仅供参考，这对我没有帮助:(
output {
value = merge(
for key, value in module.vnets:
key => value.vnets_subnets
)
}
对此的任何帮助将不胜感激！
