开启envoy 访问日志

1、静态配置文件

设置静态配置文件中

access_log:
            name: envoy.file_access_log
            typed_config:
              "@type": type.googleapis.com/envoy.config.accesslog.v2.FileAccessLog
              path: /dev/stdout

配置文件整体内容

static_resources:
  listeners:

  - address:
    socket_address:
      address: 0.0.0.0
      port_value: 82
    listener_filters:
      - name: "envoy.filters.listener.tls_inspector"
        typed_config: {}
        filter_chains:
    - filters:
      - name: envoy.filters.network.http_connection_manager
        typed_config:
          "@type": type.googleapis.com/envoy.config.filter.network.http_connection_manager.v2.HttpConnectionManager
          codec_type: auto
          stat_prefix: ingress_http
          access_log:
            name: envoy.file_access_log
            typed_config:
              "@type": type.googleapis.com/envoy.config.accesslog.v2.FileAccessLog
              path: /dev/stdout
          route_config:
            name: local_route
            virtual_hosts:
            - name: service
              domains:
              - "*"
              routes:
              - match:
                  prefix: "/"
                route:
                  cluster: ping-service
          http_filters:
            - name: envoy.filters.http.router

xds服务 数据结构makeAccessLog

manager := &hcm.HttpConnectionManager{
		CodecType:  hcm.HttpConnectionManager_AUTO,
		StatPrefix: "ingress_http",
		RouteSpecifier: &hcm.HttpConnectionManager_RouteConfig{
			RouteConfig: &v2.RouteConfiguration{
				Name:         routeConfigName,
				VirtualHosts: []*v2route.VirtualHost{&virtualHost},
			},
		},
		HttpFilters: []*hcm.HttpFilter{{
			Name: "envoy.filters.http.router",
		}},
		AccessLog: []*v21.AccessLog{
			{
				Name: "envoy.file_access_log",
				ConfigType: &v21.AccessLog_TypedConfig{
					TypedConfig: makeAccessLog(),
				},
			},
		},
	}
	
	
func makeAccessLog() *any.Any {

	acclogCfg := &acclog.FileAccessLog{
		Path: "/dev/stdout",
		/*AccessLogFormat: &acclog.FileAccessLog_Format{
			Format: "",
		},*/
	}

	pbst, err := ptypes.MarshalAny(acclogCfg)
	if err != nil {

	return pbst
