云应用 系统变量手册

一、描述

系统变量是由云应用平台注入的变量，应用开发无需关注。

·变量名都是以 cloudapp_ 开头。

·使用时需要在 tf 中声明 variable。

·系统变量名是固定的，用户无法变更。

二、使用示例

声明变量

# 系统变量variable "cloudapp_cam_role" {}variable "cloudapp_spec" {}variable "cloudapp_repo_server" {}variable "cloudapp_repo_username" {}variable "cloudapp_repo_password" {}variable "cloudapp_id" {}variable "cloudapp_name" {}variable "cloudapp_tags" {}variable "cloudapp_installer_uin" {}variable "cloudapp_owner_uin" {}variable "cloudapp_owner_appid" {}# 应用内变量variable "app_network_vpc" { type = object({ region = string availability_zone = string region_id = string vpc = object({ id = string cidr_block = string }) subnet = object({ id = string cidr_block = string zone = string }) })}variable "app_cvm" { type = object({ instance_type = string })}
variable "app_cvm_image" { type = object({ image_id = string })}variable "charge_type" { type = string default = "POSTPAID"}
variable "charge_perpaid_period" { type = number default = 1}

使用变量

resource "random_password" "password_for_cvm" { length = 16 override_special = "_+-&=!@#$%^*()"}resource "tencentcloud_instance" "main" { instance_name = "main_instance" availability_zone = var.app_network_vpc.availability_zone image_id = var.app_cvm_image.image_id #"img-mmytdhbn" instance_type = var.app_cvm.instance_type password = random_password.password_for_cvm.result vpc_id = var.app_network_vpc.vpc.id subnet_id = var.app_network_vpc.subnet.id instance_charge_type = var.charge_type == "PREPAID" ? "PREPAID" : "POSTPAID_BY_HOUR" instance_charge_type_prepaid_period = var.charge_perpaid_period cam_role_name = var.cloudapp_cam_role}

三、变量说明

当前支持的系统变量如下：
