k8s 的 ingress，似乎没法修改后端 url

Question

如果某的 service 提供的 api 是 /service/v1/module/method/resource
我想让某个地址

https://service.xxx.com/module/method/resource 

直接指向到

/service/v1/module/method/resource， 

如何配置？

Answer 1

App Root

Create an Ingress rule with a app-root annotation:

$ echo "
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/app-root: /app1
  name: approot
  namespace: default
spec:
  rules:
  - host: approot.bar.com
    http:
      paths:
      - backend:
          serviceName: http-svc
          servicePort: 80
        path: /
" | kubectl create -f -

Check the rewrite is working

$ curl -I -k http://approot.bar.com/
HTTP/1.1 302 Moved Temporarily
Server: nginx/1.11.10

Content-Length: 162
Location: http://stickyingress.example.com/app1
Connection: keep-alive

Answer 2

ingress可以监听别的端口吗
比如我有个service端口是8848，我想在公网也通过8848访问
