kubernetes-1.35.3的Ingress-nginx-1.5.1安装

 

 

案例：基于 YAML 部署 ingress-nginx

范例: 基于 kubectl apply 部署

#指定版本下载

VERSION=1.15.1

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v${VERSION}/deploy/static/provider/cloud/deploy.yaml

 

#修改三处image 地址指向国内镜像地址

[root@master1 ~]#vim deploy.yaml

默认ingress-nginx-controller只有一个Pod副本的,可选
#方法1: 指定2个副本实现高可用（此步可选）

spec:
 replicas: 2

 

 

ingress-nginx 底层基于nginx

[root@master1 ingress-nginx]# kubectl exec -it ingress-nginx-controller-65c7957ccd-75n8f -n ingress-nginx -- bash
