云原生webassembly容器 (云原生编译)

envoy 配置http下游与http上游演示如下：

static_resources:

  listeners:
  - name: listener_0
    address:
      socket_address:
        address: 0.0.0.0
        port_value: 10000 #envoy流量监听端口，类似nginx的虚拟server
    filter_chains:
    - filters:
      - name: envoy.filters.network.http_connection_manager
        typed_config:
          "@type": type.googleapis.com/envoy.extensions.filters.network.http_connection_manager.v3.HttpConnectionManager
          stat_prefix: ingress_http
          access_log:
          - name: envoy.access_loggers.stdout #日志输出配置
            typed_config:
              "@type": type.googleapis.com/envoy.extensions.access_loggers.stream.v3.StdoutAccessLog
          http_filters:
          - name: envoy.filters.http.router #路由配置(必须)
            typed_config:
              "@type": type.googleapis.com/envoy.extensions.filters.http.router.v3.Router
          route_config:
            name: local_route # 路由规则配置（类似nginx的location）
            virtual_hosts:
            - name: local_service
              domains: ["*"]
              routes:
              - match:
                  prefix: "/"
                route:
                  cluster: nginx_http

  clusters: #后端集群配置(类似nginx的upstream)
  - name: nginx_http
    load_assignment:
      cluster_name: nginx_http
      endpoints:
      - lb_endpoints:
        - endpoint:
            address:
              socket_address:
                address: 192.168.18.132 #被代理的后端服务地址
                port_value: 8000

作为后端的nginx服务配置：

    server {
        listen       8000;
        client_header_buffer_size 1k;
        large_client_header_buffers 1 2k;

        location /test {
            content_by_lua_block {
                ngx.say("你好哈")
            }
        }
   }

验证结果如下：
