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
步骤2:在集群中安装 Nginx Addon
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\\"}}}"}
步骤3:声明式安装 Nginx 实例
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"}}}}
