Question

我们玩的是docker和spring boot，这对我们来说还是个新手..

下面是我们的用例：

* There are three Spring Boot based web applications 
  - web1 = works on port 8010 = exposes API as http://...:8010/web1/rest/someEndPoint_1
  - web2 = works on port 8020 = exposes API as http://...:8020/web2/rest/someEndPoint_2 
  - web3 = works on port 8030 = exposes API as http://...:8030/web3/rest/someEndPoint_3

* All of these should be packaged in single docker image 
* Docker may have apache/haproxy/nginx and it should expose port 8080, which 

将映射到8080处的主机端口

* Here is requirement : 

  - If request will come to Docker as http://DOCKER_HOST_IP:8080/web1/rest/someEndPoint_1 
        ==> host will forward traffic to container 
        ==> Proxy running inside container will see pattern 
        ==> http://...:8010/web1/rest/someEndPoint_1

  - If request will come to Docker as http://DOCKER_HOST_IP:8080/web2/rest/someEndPoint_1 
        ==> host will forward traffic to container 
        ==> Proxy running inside container will see pattern 
        ==> http://...:8020/web2/rest/someEndPoint_1

  - If request will come to Docker as http://DOCKER_HOST_IP:8080/web3/rest/someEndPoint_1 
        ==> host will forward traffic to container 
        ==> Proxy running inside container will see pattern 
        ==> http://...:8030/web3/rest/someEndPoint_1

有可能实现吗？(基本上，我们被要求检查是否可以基于URL模式路由流量？)

请随时添加评论/编辑问题！谢谢你，谢谢你。致敬..

您正在寻找API网关，它将把传入的请求路由到一点，以提供不同的服务。您应该查看一下Spring Cloud Gateway，看看它是否能满足您的需求。

配置应该非常简单，您将在端口8080上公开您的网关，并配置到所有服务的正确路由。

之后，您将能够将所有apis聚合到一个ip:port下
