envoy 代理初始化需要 3 多分钟

如何解决envoy 代理初始化需要 3 多分钟

我正在使用 Envoy 代理路由与在 linux docker 容器上运行的多个集群的调用。我在这里观察到的初始化过程需要 3 分钟以上，这通常发生在集群的端点套接字地址错误时（这是套接字地址被标记化并且在特使代理服务器初始化期间未解析的情况）。 有什么建议可以解决这个延迟问题吗？

此外，我正在阅读有关此 initial_fetch_timeout (https://www.envoyproxy.io/docs/envoy/v1.12.0/api-v2/api/v2/core/config_source.proto#envoy-api-field-core-configsource-initial-fetch-timeout) 的信息，但对其实现的线索并不多。
