使用 csv 地形化多个 NSG

Question

我正在尝试遵循此处给出的解决方案

这是我的模块：Module-Azure-Nsg-V3/main.tf

locals {
  # read csv file
  list_of_csv_lines = csvdecode(file(var.csv_file_name))
  # collect all nsg names , (Unique)
  all_nsg_names = distinct([for item in local.list_of_csv_lines : item.nsg_name])
  # collect all nsg names other syntax , (Unique)
  all_nsg_names_again = distinct(local.list_of_csv_lines[*].nsg_name)


  # Loop over all unique names ---> for item in local.all_nsg_names : 
  # create a key of nsg name item ----> "${item}" =>
  # And to now fill value in that dictionary item key, 
  # Loop over list of csv lines  
  # pick the line 
  # if nsg_name matches item
  combine = {
      for item in local.all_nsg_names : 
        "${item}" => [
          for line in local.list_of_csv_lines : line 
          if item == line.nsg_name
        ]
  }
  


}

resource "azurerm_network_security_group" "this" {
  for_each = local.combine

  name                = each.key
  location            = var.location
  resource_group_name = var.resource_group_name
  dynamic "security_rule" {
     for_each = each.value
    
        content {
                name                        = security_rule.value["nsg_name"]
                priority                    = security_rule.value["priority"]
                direction                   = security_rule.value["direction"]
                access                      = security_rule.value["access"]
                protocol                    = security_rule.value["protocol"]
                source_port_range           = security_rule.value["source_port_range"]
                destination_port_range      = security_rule.value["destination_port_range"]
                source_address_prefix       = security_rule.value["source_address_prefix"]
                destination_address_prefix  = security_rule.value["destination_address_prefix"]
          }
  }

}



output "all-nsg-names-in-output" {
 value = local.all_nsg_names
}
output "all-nsg-names-in-output-again" {
 value = local.all_nsg_names_again
}
output "combine-output"{
  value = local.combine
}

这是我的模块：Module-Azure-Nsg-V3/variables.tf

variable "csv_file_name" {
  type = string
  default = null
}

variable "resource_group_name" {
  description = "Name of the resource Group"
  type = string
  default = null
}

variable "location" {
   description = "enviroment in which you are working"
   type = string
   default = null
}

现在我正在使用上面提到的模块来创建 NSG。

这是我的 nsg_rules.csv

nsg_name,rulename,priority,direction,access,protocol,source_port_range,destination_port_range,source_address_prefix,destination_address_prefix 
nsg01,Rule01,100,Inbound,Allow,Tcp,80,*,*,*
nsg01,Rule02,110,Inbound,Allow,Tcp,443,*,*,*
nsg02,Rule01,100,Inbound,Allow,Tcp,80,*,*,*
nsg02,Rule02,110,Inbound,Allow,Tcp,443,*,*,*
nsg03,Rule01,100,Inbound,Allow,Tcp,80,*,*,*

这是variables.tf文件

variable "csv_file_name" {
  type = string
  default = "nsg_rules.csv"
}

variable "location" {
   description = "enviroment in which you are working"
   type = string
   default = "eastus"
}


variable "resource_group_name" {
  description = "Name of the resource Group"
  type = string
  default = "terraform_rg"
}

和main.tf

module "Module-Azure-Nsg-V3" {
  source  = "./Module-Azure-Nsg-V3"
  csv_file_name = var.csv_file_name
  location = var.location
  resource_group_name = var.resource_group_name
 }

output "display_this" {
   value = module.Module-Azure-Nsg-V3.all-nsg-names-in-output
}

output "display_this_again" {
   value = module.Module-Azure-Nsg-V3.all-nsg-names-in-output-again
}
output "all-nsg-rules" {
   value = module.Module-Azure-Nsg-V3.combine-output
}

但我收到错误。

Answer 1

destination_address_prefix 实际上是 "destination_address_prefix " - 在 destination_address_prefix.[=13 之后，您的 csv 文件中有 额外的 space =]

使用 csv 地形化多个 NSG

terraform multiple NSG using csv
