注意：NginxIngress 扩展组件已停止更新，详情请参见 NginxIngress 扩展组件停止更新公告。
一、前言
这篇示例使用的环境信息如下：
·TKE 集群 Kubernetes 版本：v1.26.1
·安装 Nginx 插件版本：v1.4.1
·安装 Nginx 实例版本：v1.6.4
二、步骤1：安装 Terraform
v1.4.6版本 Release 地址为 https://releases.hashicorp.com/terraform/1.6.6/，你可以根据系统选择对应安装包。
三、步骤2：在集群中安装 Nginx Addon
Nginx Addon 插件是一个 Nginx 的安装管理工具。首先安装 Addon 插件，然后再使用插件安装 Nginx 实例，具体操作请参见 腾讯云Terraform 应用指南。
provider.tf 示例文件如下：
# 腾讯云 providerterraform { required_providers { tencentcloud = { source = "tencentcloudstack/tencentcloud" version = "1.81.61" } }}# 腾讯云 相关信息（更换密钥对 "secret_id"、"secret_key"）provider "tencentcloud" { secret_id = "********" secret_key = "********" region = "ap-shanghai"}# 安装Nginx插件（更换集群ID "cluster_id"）resource "tencentcloud_kubernetes_addon_attachment" "addon_ingressnginx" { cluster_id = "cls-xxxxxxxx" name = "ingressnginx" request_body = "{\\"kind\\":\\"App\\",\\"spec\\":{\\"chart\\":{\\"chartName\\":\\"ingressnginx\\",\\"chartVersion\\":\\"1.4.1\\"}}}"}
四、步骤3：声明式安装 Nginx 实例
有关 Kubernetes Provider 的更多配置信息，请参见 产品文档。
Nginx 实例的相关配置可以根据需要进行修改。
·IngressClass 配置（示例中使用的是 demo）
·HPA 配置
·requests/limits 配置
provider.tf 示例文件如下：
provider "kubernetes" { config_path = "~/.kube/config"}resource "kubernetes_manifest" "nginxingress_demo" { manifest = { "apiVersion" = "cloud.tencent.com/v1alpha1" "kind" = "NginxIngress" "metadata" = { "name" = "demo" } "spec" = { "ingressClass" = "demo" "service" = { "annotation" = { "service.kubernetes.io/service.extensiveParameters" = "{\\"InternetAccessible\\":{\\"InternetChargeType\\":\\"TRAFFIC_POSTPAID_BY_HOUR\\",\\"InternetMaxBandwidthOut\\":10}}" } "type" = "LoadBalancer" } "workLoad" = { "hpa" = { "enable" = true "maxReplicas" = 2 "metrics" = [ { "pods" = { "metricName" = "k8s_pod_rate_cpu_core_used_limit" "targetAverageValue" = "80" } "type" = "Pods" }, ] "minReplicas" = 1 } "template" = { "affinity" = {} "container" = { "image" = "ccr.ccs.tencentyun.com/tkeimages/nginx-ingress-controller:v1.6.4" "resources" = { "limits" = { "cpu" = "0.5" "memory" = "1024Mi" } "requests" = { "cpu" = "0.25" "memory" = "256Mi" } } } } "type" = "deployment" } } }}
