• helm v3 部署 ingressnginx


    1、部署 helm v3 略...(https://www.cnblogs.com/lfl17718347843/p/15709353.html)
    2、添加源并更新

    [root@master1 ingress]# helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
    
    [root@master1 ingress]# helm repo update
    

    3、拉取镜像

    [root@master1 ingress]# helm pull ingress-nginx/ingress-nginx
    

    4、解压并修改 value.yaml 文件

    [root@master1 ~]# cat /root/ingress/ingress-nginx/values.yaml

    5、选择节点打 label

    kubectl label node xxx ingress=true     (xxx是节点,根据自己要部署的节点打标签)
    

    6、创建一个ingress的namespace

    kubectl create ns ingress-nginx
    

    7、安装 ingress-nginx

    helm install nginx-ingress -n ingress-nginx .
    出现以下提示:代表成功
    NAME: ingress-nginx
    .......
    .......
    .......
     data:
        tls.crt: <base64 encoded cert>
        tls.key: <base64 encoded key>
