容器服务通过 Terraform 安装 Nginx 插件和实例-TKE 标准集群指南-文档中心-腾讯云

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。
前言
本文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
步骤1：安装 Terraform
您可以通过以下命令下载并安装 Terraform：
wget https://releases.hashicorp.com/terraform/1.6.6/terraform_1.6.6_linux_amd64.zip
v1.4.6版本 Release 地址为 https://releases.hashicorp.com/terraform/1.6.6/，您可以根据系统选择对应安装包。
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 provider
terraform {
  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\\"}}}"
}
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 官方文档。
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"
      }
    }
  }
}
