Ingress Nginx基本认证

1.使用htpasswd工具创建生成nginx认证用户

1.安装htpasswd工具

# yum install httpd -y

2.使用htpasswd工具生成测试用户名和密码

# htpasswd -c auth admin
New password: 
Re-type new password: 
Adding password for user admin
​
# ls auth 
auth
# cat auth 
admin:$apr1$GMNGjVIB$TJYrLDghftoZa.fAu9c3Q/
​

2.将创建的密码文件用secrets资源存储

#  kubectl create secret generic nginx-basic-auth --from-file=auth 
secret/nginx-basic-auth created
#  kubectl get secrets nginx-basic-auth 
NAME               TYPE     DATA   AGE
nginx-basic-auth   Opaque   1      81s
​

3.部署测试应用

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  labels:
    app: nginx
  namespace: default
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx
      containers:
        - name: nginx
          image: nginx:1.15.2
          ports:
            - name: nginxprot
              containerPort: 80
              protocol: TCP
              
​
apiVersion: v1
kind: Service
metadata:
  name: nginx
  namespace: default
  labels:
    app: nginx
spec:
  ports:
    - name: nginxprot
      protocol: TCP
      port: 80
      targetPort: 80
  selector:
    app: nginx
  type: ClusterIP
​

4.创建Ingress用于认证信息

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-basic-auth
  namespace: default
  generation: 1
  annotations:
    # 登录的提示信息
    nginx.ingress.kubernetes.io/auth-realm: Please Input Your Username and Passowrd
    # 对应认证信息，也就是我们创建的secrets资源名称，里面保存了我们创建的有效用户
    nginx.ingress.kubernetes.io/auth-secret: nginx-basic-auth
    # 指定认证类型
    nginx.ingress.kubernetes.io/auth-type: basicbernetes.io/auth-type: basic
spec:
  ingressClassName: nginx
  rules:
    - host: ingress.basic.auth
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: nginx
                port:
                  number: 80
​
