ingress-nginx安装

1.通过helm安装

1.添加仓库
[root@master01 ~]# helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
2.更新
[root@master01 ~]# helm repo update
3.拉取ingress
[root@master01 ~]# mkdir -p ingress && cd ingress && helm fetch ingress-nginx/ingress-nginx
4.解压
[root@master01 ~]# tar -xvf ingress-nginx-3.15.2.tgz

2.更改模板

[root@master01 ingress-nginx]# pwd
/root/ingress/ingress-nginx
[root@master01 ingress-nginx]# cat values-prod.yaml 
controller:
  name: controller
  image:
    repository: cnych/ingress-nginx
    tag: "v0.41.2"
    digest: 

  dnsPolicy: ClusterFirstWithHostNet
   
  hostNetwork: true

  publishService:  # hostNetwork 模式下设置为false，通过节点IP地址上报ingress status数据
    enabled: false

  kind: DaemonSet

  nodeSelector: 
    kubernetes.io/os: linux
    ingress: "true"
  service:  # HostNetwork 模式不需要创建service
    enabled: false

defaultBackend:
  enabled: true
  name: defaultbackend
  image:
    repository: cnych/ingress-nginx-defaultbackend
    tag: "1.5"

3.创建命名空间,安装ingress-nginx

1.创建命名空间
[root@master01 ~]# kubectl create ns ingress-nginx 
2.指定节点打标签，指定调度
[root@master01 ~]#  kubectl label node node01 ingress=true
3.安装ingress
[root@master01 ingress]# pwd
/root/ingress
[root@master01 ~]# helm install --namespace ingress-nginx ingress-nginx ./ingress-nginx -f ./ingress-nginx/values-prod.yaml
4.查看ingress pod是否成功
[root@master01 ingress]# kubectl get pod -n ingress-nginx  -owide
NAME                                            READY   STATUS    RESTARTS   AGE   IP              NODE     NOMINATED NODE   READINESS GATES
ingress-nginx-controller-nzl8h                  1/1     Running   0          16m   192.168.0.121   node01   <none>           <none>
ingress-nginx-defaultbackend-796bdb7766-p4qj8   1/1     Running   0          16m   10.244.2.158    node02   <none>           <none>
[root@master01 ingress]# kubectl get svc -n ingress-nginx 
NAME                                 TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)   AGE
ingress-nginx-controller-admission   ClusterIP   10.100.115.15   <none>        443/TCP   17m
ingress-nginx-defaultbackend         ClusterIP   10.108.152.89   <none>        80/TCP    17m

4.简单测试下
