1 Ingress 进行 BasicAuth 认证

借用 http 的 htpasswd 模块，创建auth文件

yum -y install httpd
mkdir basic-auth
cd basic-auth/
htpasswd -c auth admin    #admin是认证的用户
New password: 123.com    #123.com 是 admin认证的密码
Re-type new password:123.com

在k8s集群中创建secret

kubectl create secret generic basic-auth --from-file=auth

在ingress.yaml中添加配置

apiVersion: extensions/v1beta1
kind: Ingress
metadata: 
  name: ingress-with-auth
  annotations: 
    nginx.ingress.kubernetes.io/auth-type: basic
    nginx.ingress.kubernetes.io/auth-secret: basic-auth
    nginx.ingress.kubernetes.io/auth-realm: 'Authentication Required - admin'
spec:
 rules:
   - host: auth.ng.com
     http:
      paths:
        - path: /
          backend: 
            serviceName: ng-svc
            servicePort: 80
