terraform - 如何根据 if else 条件 terraform 过滤来自当地人的数据？

Question

主文件

locals {
    location_mapping = [
    {
        "url": "L1.tfe.com"
        "location": "L1"
        "resource_group_name": "R1"
        "name_log_workspace_name": "W1"
    },
    {
        "url": "L2.tfe.com"
        "location": "L2"
        "resource_group_name": "R2"
        "name_log_workspace_name": "W2"
    },
    {
        "url": "L3.tfe.com"
        "location": "L3"
        "resource_group_name": "R3"
        "name_log_workspace_name": "W3"
    }
    ]
}

data "azurerm_log_analytics_workspace" "example" {
    # Populate name and resource group based on var.location(L2) condition if location matches in locals
    name                = "W2"
    resource_group_name = "R2"
}

我想根据本地数据块中的条件动态填充名称和资源组名称。location and url

例子

如果我通过location value L2然后url value L2.tfe.com我会name=W2得到resource_group_name=R2

Answer 1

我认为以下内容应该是合适的，假设只能有一场比赛：

variable "location" {
  default = "L2"
}

variable "url" {
  default = "L2.tfe.com"
}

locals {
    location_mapping = [
    {
        "url": "L1.tfe.com"
        "location": "L1"
        "resource_group_name": "R1"
        "name_log_workspace_name": "W1"
    },
    {
        "url": "L2.tfe.com"
        "location": "L2"
        "resource_group_name": "R2"
        "name_log_workspace_name": "W2"
    },
    {name_log_workspace_name
        "url": "L3.tfe.com"
        "location": "L3"
        "resource_group_name": "R3"
        "name_log_workspace_name": "W3"
    }
    ]
    
   selected_mapping = lookup({for val in local.location_mapping:
                           0 => val if val.location == var.location  &&
                          val.url == var.url}, 0,
                       {
                            "url": "default"
                            "location": "default_L"
                            "resource_group_name": "default_R"
                            "name_log_workspace_name": "default_W"
                       })
    
}

data "azurerm_log_analytics_workspace" "example" {    
    name                = local.selected_mapping.name_log_workspace_name
    resource_group_name = local.selected_mapping.resource_group_name
}
