[英]How to loop correctly in terraform for_each?
Objective : Loop through azure subnets via terraform.目标:通过 terraform 遍历 azure 子网。
Code That I use:我使用的代码:
Main.tf:
resource "azurerm_network_security_group" "nsg" {
name = "nsg-vnet-hub-${var.env}-indoundDNS"
location = azurerm_resource_group.rg[0].location
resource_group_name = azurerm_resource_group.rg[0].name
tags = {
environment = "${var.env}"
costcentre = "12345"
}
}
resource "azurerm_monitor_diagnostic_setting" "nsg" {
for_each = var.subnets
name = lower("${each.key}-diag")
target_resource_id = azurerm_network_security_group.nsg[each.key].id
storage_account_id = azurerm_storage_account.storeacc.id
log_analytics_workspace_id = azurerm_log_analytics_workspace.logws.id
dynamic "log" {
for_each = var.nsg_diag_logs
content {
category = log.value
enabled = true
retention_policy {
enabled = false
}
}
}
}
My root module variable.tf
:我的根模块
variable.tf
:
variable "subnets" {
type = map(object({
name = string
}))
default = {
"s1" = { name = "dns_snet"},
"s2" = { name = "common_snet"},
"s3" = { name = "gw_snet"},
"s4" = { name = "data_snet"}
}
}
Problem I am facing:我面临的问题:
Error:错误:
network_security_group_id = azurerm_network_security_group.nsg[each.key].id
│ ├────────────────
│ │ azurerm_network_security_group.nsg is object with 7 attributes
│ │ each.key is "s3"
│
│ The given key does not identify an element in this collection value
Just updated this post, now I get error as above.刚刚更新了这篇文章,现在我得到了上面的错误。 I am referring to below documentation
我指的是以下文档
https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/network_security_group https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/network_security_group
You have only a single instance of azurerm_network_security_group.nsg
.您只有一个
azurerm_network_security_group.nsg
实例。 Thus there is nothing to iterate over.因此没有什么可以迭代的。 To fix your error, it should be:
要修复您的错误,它应该是:
target_resource_id = azurerm_network_security_group.nsg.id
