Kubernetes Ingress网络拒绝某些路径 [英] Kubernetes Ingress network deny some paths

问题描述

我有一个简单的kubernetes入口网络.

I've a simple kubernetes ingress network.

我需要拒绝访问一些关键路径，例如/admin等.

I need deny the access some critical paths like /admin or etc.

我的入口网络文件如下所示.

My ingress network file shown as below.

 apiVersion: extensions/v1beta1
 kind: Ingress
 metadata:
 name: ingress-test
 spec:
   rules:
   - host: host.host.com
   http:
      paths:
        - path: /service-mapping
      backend:
         serviceName: /service-mapping
         servicePort: 9042

如何使用kubernetes入口网络，nginx注释或其他方法拒绝自定义路径.

How I can deny the custom path with kubernetes ingress network, with nginx annonations or another methods .

我通过如下所示的注释来处理此问题.

I handle this issue with annotations shown as below .

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
   name: nginx-configuration-snippet
   annotations:
      nginx.ingress.kubernetes.io/configuration-snippet: |

     server_tokens off;
     location DANGER-PATH {
    deny all;
    return 403;
  }

spec:
  rules:
   - host: api.myhost.com
   http:
  paths:
  - backend:
      serviceName: bookapi-2
      servicePort: 8080
    path: PATH 

推荐答案

我遇到了同样的问题，并在

I’ve faced the same issue and found the solution on github. To achieve your goal, you need to create two Ingresses first by default without any restriction:

apiVersion: extensions/v1beta1
 kind: Ingress
 metadata:
 name: ingress-test
 spec:
   rules:
   - host: host.host.com
   http:
      paths:
        - path: /service-mapping
      backend:
         serviceName: /service-mapping
         servicePort: 9042

然后，按照

Then, create a secret for auth as described in the doc:

创建htpasswd

$ htpasswd -c auth foo
New password: <bar>
New password:
Re-type new password:
Adding password for user foo

创建secret:

$ kubectl create secret generic basic-auth --from-file=auth
secret "basic-auth" created

具有auth的第二个入口，用于您需要限制的路径:

Second Ingress with auth for paths which you need to restrict:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-with-auth
  annotations:
    # type of authentication
    nginx.ingress.kubernetes.io/auth-type: basic
    # name of the secret that contains the user/password definitions
    nginx.ingress.kubernetes.io/auth-secret: basic-auth
    # message to display with an appropiate context why the authentication is required
    nginx.ingress.kubernetes.io/auth-realm: "Authentication Required - foo"
spec:
  rules:
  - host: host.host.com
    http:
      paths:
      - path: /admin
        backend:
          serviceName: service_name
          servicePort: 80
