[英]Nginx Ingress controller- Path based routing
我正在运行 Nginx 入口 controller 并希望只允许用户连接的少数路径和 rest 所有我想阻止或提供 403 错误。 我怎样才能做到这一点?
我只希望用户允许连接/example
和 rest 都应该被阻止。
kind: Ingress
metadata:
name: ingress1
annotations:
kubernetes.io/ingress.class: nginx
spec:
rules:
- host: ingress.example.com
http:
paths:
- path: /example
backend:
serviceName: ingress-svc
servicePort: 80
我可以添加 nginx 服务器片段吗?
location path {
"if the path is not matching then deny"
deny all;
}```
使用下面的自定义后端
apiVersion: apps/v1
kind: Deployment
metadata:
name: custom-http-backend
spec:
selector:
matchLabels:
app: custom-http-backend
template:
metadata:
labels:
app: custom-http-backend
spec:
containers:
- name: custom-http-backend
image: inanimate/echo-server
ports:
- name: http
containerPort: 8080
imagePullPolicy: IfNotPresent
---
apiVersion: v1
kind: Service
metadata:
name: custom-http-backend
spec:
selector:
app: custom-http-backend
ports:
- protocol: TCP
port: 80
targetPort: 8080
然后在您的入口添加此规则
- host: ingress.example.com
http:
paths:
- path: /
backend:
serviceName: custom-http-backend
servicePort: 80
除了@Tarun Khosla 提到的正确之外,还有另一个带有示例的stackoverflow 问题可能会有所帮助。 我将其发布为社区 wiki 答案,以便为社区提供更好的可见性,请随时对其进行扩展。
@Nick Rak 提供了 2 个示例
我遇到了同样的问题,并在github上找到了解决方案。 为了实现你的目标,你需要先默认创建两个 Ingress,没有任何限制:
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,按照文档中的描述为身份验证创建一个secret
:
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
对于您需要限制的路径,具有身份验证的第二个 Ingress:
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
