Is it possible port forwarding with spring cloud starter zuul?

In respect of spring cloud starter zuul we could route request path by following configuration:

application.yml

server:
  port: 80
zuul:
  routes:
    amqp:
      url: http://127.0.0.1:8010/amqp
    astm:
      url: http://127.0.0.1:8011/astm
    mllp:
      url: http://127.0.0.1:8012/mllp
    labs:
      url: http://127.0.0.1:8013/labs

Using this configuration request from http://127.0.0.1/mllp routed to http://127.0.0.1:8012/mllp. But I would like to use it for port-forwarding, Is it possible? lets say for :

============================================
  request                 forwarded
tcp ip:port              tcp ip:port
============================================
0.0.0.0:22210            192.168.0.10:22210
0.0.0.0:55510            192.168.0.11:55510
============================================

If possible how to configure it? Or any easy mechanism in spring boot application for port-forwarding?

Solution

  • You mean as some kind of HAProxy replacement which runs service agnostic? Then the answer is: no! As you can see from the Zuul Wiki its only purpose is to filter and route HttpRequests and HttpResponses. You'll also find out the same by checking the code of ZuulServlet which just handles HttpServletRequests and HttpServletResponses.
