Envoy 作为 unix 套接字的反向代理和负载均衡器答案

【问题标题】：Envoy as a reverse proxy and load balancer for unix socketsEnvoy 作为 unix 套接字的反向代理和负载均衡器
【发布时间】：2020-02-21 09:40:26
【问题描述】：

我有以下问题：envoy 应该对许多 unix 套接字进行反向代理，例如：

/var/run/node1.sock
/var/run/node2.sock
...

等等。我试过的配置都没有工作，特使甚至没有启动。有人能解释一下如何反向代理甚至是单个 unix 套接字吗？

已解决：

     - lb_endpoints:
        - endpoint:
            address:
              pipe:
                path: /var/run/node1.sock
        - endpoint:
            address:
              pipe:
                path: /var/run/node2.sock
