我想在路由配置中设置一些元数据，并将它们放在访问日志中。我知道该功能是https://github.com/envoyproxy/envoy/pull/4862。
但是，我无法弄清楚如何编写yaml文件，我尝试了很多次，但它不起作用。
admin:
access_log_path: /tmp/admin_access.log
address:
socket_address: { address: 0.0.0.0, port_value: 9901 }
static_resources:
listeners:
- name: listener_0
address:
socket_address: { address: 0.0.0.0, port_value: 10000 }
filter_chains:
- filters:
- name: envoy.http_connection_manager
config:
tracing:
operation_name: ingress
use_remote_address: true
add_user_agent: true
generate_request_id: true
stat_prefix: ingress_http

route_config:

virtual_hosts:

route: { cluster: some_serviceA }

hosts: [{ socket_address: { address: 127.0.0.1, port_value: 5001 }}]
- name: accesslog_cluster
connect_timeout: 2s
hosts:
- socket_address:
address: 127.0.0.1
port_value: 18090
http2_protocol_options: {}
但是我从通用元数据中一无所获。
是否有将元数据设置为访问日志的示例？
