1、在ACK管理控制台点击如下

应用市场–>筛选(以ack-ingress-nginx-v1为例)–>点击安装–>一键部署–>自己定义集群、命名空间以及ingress名称

1.20以下集群选中ack-ingress-nginx。

1.20及以上集群选中ack-ingress-nginx-v1。

在这里插入图片描述
筛选(以ack-ingress-nginx-v1为例)并点击安装

一键部署

自己定义集群、命名空间以及ingress名称

  ## Improve connection draining when ingress controller pod is deleted using a lifecycle hook:
  ## With this new hook, we increased the default terminationGracePeriodSeconds from 30 seconds
  ## to 300, allowing the draining of connections up to five minutes.
  ## If the active connections end before that, the pod will terminate gracefully at that time.
  ## To effectively take advantage of this feature, the Configmap feature
  ## worker-shutdown-timeout new value is 240s instead of 10s.

同时记得留意以下的值
ack-ingress-nginx-v1主要参数如下表

参数	默认值	描述
controller.image.repository	registry-vpc.cn-hongkong.aliyuncs.com/acs/aliyun-ingress-controller	ingress-nginx镜像地址
controller.image.tag	v1.2.1-aliyun.1	ingress-nginx镜像版本，请参见Nginx Ingress Controller
controller.ingressClassResource.name	ack-nginx	设置Ingress Controller所对应的IngressClass的名称。重要该参数作为1.22以下版本模板中controller.ingressClass参数的替代，可以在kubernetes.io/ingress.class注解中正常使用。同一个集群中不同套Ingress Controller创建的IngressClass名称必须唯一，且不能设置为nginx关键字（nginx是集群默认Ingress Controller的监听标识）。
controller.ingressClassResource.controllerValue	k8s.io/ack-ingress-nginx	设置Ingress Controller所对应的Controller Class。重要同一个集群中不同套Ingress Controller创建的Controller Class必须唯一，且不能设置为k8s.io/ingress-nginx关键字（k8s.io/ingress-nginx是集群默认Ingress Controller的监听标识）。
controller.replicaCount	2	设置该Ingress Controller Pod的副本数。
controller.service.enabled	true	是否启用SLB访问（包括公网和私网）。
controller.service.external.enabled	true	是否开启公网SLB访问，不需要开启则设置为false。
controller.service.internal.enabled	false	是否开启私网SLB访问，需要开启则设置为true。
controller.kind	Deployment	设置IngressController部署形态，可选值：Deployment和DaemonSet。
controller.electionID	ingress-controller-leader	选主时使用的ID，用于更新Ingress端点状态。重要若通过应用市场部署多套Nginx Ingress Controller至同一命名空间下，需要将electionID设置为不同的值，避免选主冲突。
controller.metrics.enabled	false	是否开启ingress-nginx的metrics。
controller.metrics.serviceMonitor.enabled	false	是否开启serviceMonitor，配置抓取规则。说明建议开启ingress-nginx的metrics后，同时开启此选项，以此来自动配置Prometheus的抓取规则。
