由route定义的路由目标必须是cluster(上游集群名称)、cluster_header(根据请求标头中的cluster_header的值确定目标集群)或weighted_clusters(路由目标有多个集群,每个集群拥有一定的权重)其中之一; redirect则返回一个重定向。 direct_response直接返回任意HTTP响应,无需代理。 routes:-name:...# 此路由条目的名称;match:...

direct_response直接应答 route路由 route: image 1、管理接口admin的介绍 Envoy内建了一个管理服务(administration server ),它支持查询和修改操作,甚至有可能暴 露私有数据(例如统计数据、集群名称和证书信息等),因此非常有必要精心编排其访问控 制机制以避免非授权访问。
