&lt;h2 id="简要概述">简要概述&lt;/h2>
&lt;p>Envoy 是为面向服务架构（SOA）设计的 L7 层代理，主要围绕解决以下核心思想：&lt;/p>
&lt;blockquote>
&lt;p>&lt;strong>网络应对应用程序透明，当网络和应用程序发生问题时，应该很容易确定问题的根源。&lt;/strong>&lt;/p>
&lt;/blockquote>
&lt;h2 id="功能特点">功能特点&lt;/h2>
&lt;p>实现上述的目标非常困难，在设计上试图通过提供以下高级功能来实现这一目标：&lt;/p>
&lt;ul>
&lt;li>独立进程架构&lt;/li>
&lt;/ul>
&lt;p>相比传统的 sdk 方式，部署升级更加简单方便；&lt;/p>
&lt;ul>
&lt;li>L3/L4 过滤器架构&lt;/li>
&lt;/ul>
&lt;p>可插拔的过滤器链机制，可方便为 TCP/UDP 代理编译各自自定义任务；&lt;/p>
&lt;ul>
&lt;li>HTTP L7 过滤器架构&lt;/li>
&lt;/ul>
&lt;p>方便为 HTTP 协议添加执行不同的任务，如缓冲、速率限制、路由/转发；&lt;/p>
&lt;ul>
&lt;li>优先支持 HTTP/2&lt;/li>
&lt;/ul>
&lt;p>推荐服务使用 h2 以创建持久连接的网格，使得请求和响应可以通过多路复用；&lt;/p>
&lt;ul>
&lt;li>HTTP/3 支持&lt;/li>
&lt;/ul>
&lt;p>支持上行和下行的HTTP/3，并能够在任何方向上进行HTTP/1.1、HTTP/2和HTTP/3的相互转换；&lt;/p>
&lt;ul>
&lt;li>HTTP L7 路由&lt;/li>
&lt;/ul>
&lt;p>支持一个路由子系统，能够根据路径、权限、内容类型、运行时值等路由和重定向请求；&lt;/p>
&lt;ul>
&lt;li>gRPC 支持&lt;/li>
&lt;/ul>
&lt;p>支持为 gRPC 请求和响应的路由和负载均衡；&lt;/p>
&lt;ul>
&lt;li>服务发现和动态配置&lt;/li>
&lt;/ul>
&lt;p>支持 API 以及可动态更新集群本身能力；&lt;/p>
&lt;ul>
&lt;li>健康检查&lt;/li>
&lt;/ul>
&lt;p>内置健康检查子系统，可以选择对上游服务集群执行主动的健康检查；&lt;/p>
&lt;ul>
&lt;li>高级负载均衡&lt;/li>
&lt;/ul>
&lt;p>原生提供诸如自动重试、断路器、限速、异常检查等功能，并使其对任何应用程序都可使用；&lt;/p>
&lt;ul>
&lt;li>前/边缘代理支持&lt;/li>
&lt;/ul>
&lt;p>原先提供了可观察性、管理、服务发现和负载均衡等非常易于在边缘端使用；&lt;/p>
&lt;ul>
&lt;li>丰富的可观测性&lt;/li>
&lt;/ul>
&lt;p>为所有子系统提供了统计支持，对外暴露性能数据。&lt;/p>
&lt;h2 id="关键术语">关键术语&lt;/h2>
&lt;table>
&lt;thead>
&lt;tr>
&lt;th>术语&lt;/th>
&lt;th>名称&lt;/th>
&lt;th>说明&lt;/th>
&lt;/tr>
&lt;/thead>
&lt;tbody>
&lt;tr>
&lt;td>Host&lt;/td>
&lt;td>主机&lt;/td>
&lt;td>逻辑网络应用程序&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>Downstream&lt;/td>
&lt;td>下游&lt;/td>
&lt;td>下游客户端主机连接到 Envoy，发送请求并接收响应&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>Upstream&lt;/td>
&lt;td>上游&lt;/td>
&lt;td>上游服务端主机接收来自 Envoy 的连接和请求，并返回响应&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>Listener&lt;/td>
&lt;td>监听器&lt;/td>
&lt;td>提供给下游客户端连接的网络地址&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>Cluster&lt;/td>
&lt;td>集群&lt;/td>
&lt;td>Envoy 连接到逻辑上相同的一组上游主机&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>Mesh&lt;/td>
&lt;td>网格&lt;/td>
&lt;td>一组 Envoy 代理，它们之间互相协调网络拓扑&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>Runtime configuration&lt;/td>
&lt;td>运行时配置&lt;/td>
&lt;td>可以更改配置设置来影响运行，而无需重启 Envoy 或更改主要配置&lt;/td>
&lt;/tr>
&lt;/tbody>
&lt;/table>
&lt;h2 id="xds">xDS&lt;/h2>
&lt;p>Envoy xDS APIs（xDS 协议）使用 proto3 编写定义在官方代码仓库 &lt;a href="https://github.com/envoyproxy/envoy/blob/main/api">api&lt;/a> 中，它们支持：&lt;/p>
&lt;ol>
&lt;li>通过 gRPC 进行 xDS API 更新&lt;/li>
&lt;li>自动通过 proto3 映射为 reset api&lt;/li>
&lt;li>支持本地配置文件、REST 接口 或 gRPC 端点传递更新&lt;/li>
&lt;li>通过扩展的端点分配 API 进行高级负载均衡&lt;/li>
&lt;li>TODO; 在需要时提供更强的一致性和排序特性&lt;/li>
&lt;/ol>
&lt;h2 id="启动配置">启动配置&lt;/h2>
&lt;h3 id="示例配置">示例配置&lt;/h3>
&lt;p>在使用 xDS API，需提供引导配置文件以启动服务，支持两种配置：&lt;/p>
&lt;ol>
&lt;li>静态配置（static_resources），启动前人工已编写好；&lt;/li>
&lt;li>动态配置（dynamic_resources），通过 xDS 服务端自发现；&lt;/li>
&lt;/ol>
&lt;p>以下是静态配置的示例：&lt;/p>
&lt;div class="highlight">&lt;pre tabindex="0" style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-yaml" data-lang="yaml">&lt;span style="display:flex;">&lt;span>&lt;span style="color:#000">cat &amp;gt;&amp;gt; demo.yaml &amp;lt;&amp;lt; EOF&lt;/span>&lt;span style="color:#f8f8f8;text-decoration:underline">

&lt;p>Envoy 支持在单个进程中使用任意数量的监听器配置，一般我们建议一台主机仅运行一个进程，而不管监听器数量。&lt;/p>
&lt;p>支持 TCP 与 UDP 监听器。&lt;/p>
&lt;h2 id="tcp-监听器">TCP 监听器&lt;/h2>
&lt;p>每个监听器都配置了独立的网络层过滤器链（filter_chains），它由一个或多个网络层（L3/L4）过滤器组成，常见的有：&lt;/p>
&lt;table>
&lt;thead>
&lt;tr>
&lt;th>名称&lt;/th>
&lt;th>描述&lt;/th>
&lt;th>类型&lt;/th>
&lt;/tr>
&lt;/thead>
&lt;tbody>
&lt;tr>
&lt;td>rate limiting&lt;/td>
&lt;td>限速&lt;/td>
&lt;td>x&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>TLS client authentication&lt;/td>
&lt;td>TLS 客户端身份验证&lt;/td>
&lt;td>x&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>HTTP connection management&lt;/td>
&lt;td>HTTP 连接管理&lt;/td>
&lt;td>x&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>MongoDB sniffing&lt;/td>
&lt;td>mongodb 嗅探&lt;/td>
&lt;td>x&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>raw TCP proxy&lt;/td>
&lt;td>原始 TCP 代理&lt;/td>
&lt;td>x&lt;/td>
&lt;/tr>
&lt;/tbody>
&lt;/table>
&lt;p>当在监听器上接收到新连接时，根据配置的 &amp;ldquo;filter_chain_match&amp;rdquo; 条件选择适当的过滤器（filter_chain）然后开始处理后续事件。&lt;/p>
&lt;p>监听器也可以选择配置监听器过滤器（listener filters），这些过滤器在网络层过滤器之前进行处理，并有机会操作连接元数据，通常是为了影响后续过滤器或集群如何处理连接。&lt;/p>

&lt;p>与网络级别过滤器一样，HTTP过滤器可以停止并继续迭代到后续过滤器。这允许更复杂的场景，如处理健康检查、调用速率限制服务、缓冲、路由、为应用程序流量生成DynamoDB等的统计信息。&lt;/p>
&lt;p>编写过滤器无需过多底层协议知识，主要有三种类型：&lt;/p>
&lt;ol>
&lt;li>Decoder（解码器）&lt;/li>
&lt;/ol>
&lt;p>当连接管理器解码请求流的部分（请求头、请求体和尾部）时，将调用解码器过滤器。&lt;/p>
&lt;ol start="2">
&lt;li>Encoder（编码器）&lt;/li>
&lt;/ol>
&lt;p>当连接管理器即将对部分响应流（响应头、响应体和尾部）进行编码时，将调用编码器过滤器。&lt;/p>
&lt;ol start="3">
&lt;li>Decoder/Encoder （解码器/编码器）&lt;/li>
&lt;/ol>
&lt;p>当连接管理器解码请求流的部分以及当连接管理器即将编码响应流的部分时，将同时调用解码器/编码器过滤器。&lt;/p>
&lt;h3 id="过滤器执行顺序">过滤器执行顺序&lt;/h3>
&lt;p>假设以下三个过滤器均是 &amp;ldquo;Decoder/Encoder&amp;rdquo; 类型：&lt;/p>

&lt;p>路由作用域（Route Scope）用于将特定路由规则与某个作用域（scope）相关联，每个请求都会计算一个作用域键（scope key），并根据这个键来选择相应的路由规则，涉及以下两个概念：&lt;/p>
&lt;ol>
&lt;li>Scope Key（作用域键）： 对于每个请求，HTTP 连接管理器会动态计算一个作用域键，这个键用于决定选择哪个路由表。作用域键的计算可能基于请求的某些属性或上下文信息。&lt;/li>
&lt;li>Route Table（路由表）： 路由表是一组与特定作用域键相关联的路由规则。每个路由表定义了一组路由规则，当请求的作用域键与路由表相关联时，Envoy 将使用这个路由表来确定请求的最终路由。&lt;/li>

&lt;p>在配置中定义上游集群时，Envoy需要知道如何解析集群的成员。这被称为服务发现。&lt;/p>
&lt;p>在 envoy 上最佳案例是使用最终一致的服务发现以及主动健康检查（Envoy 显式地对上游集群成员进行健康检查）来确定集群健康，而不是类似其他Zookeeper、etcd、Consul 等做一致性协调。&lt;/p>
&lt;h3 id="static">STATIC&lt;/h3>
&lt;p>静态是最简单的服务发现类型。配置明确指定了每个上游主机的解析网络名称（IP地址/端口、Unix域套接字等）。&lt;/p>

&lt;p>在大规模网络中，如果上游服务对外提供 HTTP 健康检查地址（如：&amp;quot;/ping&amp;quot;），下游探测器（如：prometheus）请求这类地址可能会产生较大的健康检查流量，你可以通过 &lt;a href="https://www.envoyproxy.io/docs/envoy/latest/configuration/http/http_filters/health_check_filter">HTTP 健康检查过滤器&lt;/a>（配置在 http_filters 中）适当缓存以降低这种流量回到上游服务中，支持以下几种模式：&lt;/p>
&lt;ol>
&lt;li>不透传（No pass through）&lt;/li>
&lt;/ol>
&lt;p>下游请求这类健康检查 URL 地址永远不会传递到上游服务，根据服务器当前的状态，Envoy 将回复 200 或 503。&lt;/p>

&lt;h2 id="异常值检测">异常值检测&lt;/h2>
&lt;p>它也称为被动健康检查，在 &lt;a href="https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/cluster/v3/outlier_detection.proto#">config.cluster.v3.OutlierDetection&lt;/a> 配置，区别于主动健康检查，在 &lt;a href="https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/core/v3/health_check.proto#config-core-v3-healthcheck">config.core.v3.HealthCheck&lt;/a>，它们可以配合使用也可以单独使用。&lt;/p>
&lt;p>异常值检测是动态确定上游集群中某些主机的性能是否与其他主机不同，并将其从健康负载均衡集中移除的过程。常见的异常值包含：连续的故障、时间成功率、时间延迟等，它需要过滤器来报告数据，当前仅以下过滤器支持：[http router]，[tcp proxy]，[redis proxy]，[thrift proxy]&lt;/p>
&lt;p>检测错误分为两类：&lt;/p>
&lt;ol>
&lt;li>外部生成的错误&lt;/li>
&lt;/ol>
&lt;p>外部生成的错误是事务特定的，发生在上游服务器对接收到的请求做出响应时。例如，HTTP服务器返回错误代码500或者redis服务器返回无法解码的有效负载。这些错误是在Envoy成功连接到上游主机之后由上游主机生成的。&lt;/p>
&lt;ol start="2">
&lt;li>本地生成的错误&lt;/li>
&lt;/ol>
&lt;p>由 Envoy 生成的，响应于中断或阻止与上游主机通信的事件。本地生成错误的例子包括超时、TCP复位、无法连接到指定端口等。&lt;/p>
&lt;h3 id="连续的-5xx-错误">连续的 5xx 错误&lt;/h3>
&lt;p>TODO;&lt;/p>
&lt;h3 id="网关连续故障">网关连续故障&lt;/h3>
&lt;p>TODO;&lt;/p>
&lt;h3 id="连续本地起源失败">连续本地起源失败&lt;/h3>
&lt;p>TODO;&lt;/p>
&lt;h3 id="成功率">成功率&lt;/h3>
&lt;p>TODO;&lt;/p>
&lt;h3 id="失败率">失败率&lt;/h3>
&lt;p>TODO;&lt;/p>
&lt;h3 id="异常检测日志">异常检测日志&lt;/h3>
&lt;p>TODO;&lt;/p>
&lt;h2 id="负载均衡">负载均衡&lt;/h2>
&lt;p>TODO;&lt;/p>
&lt;h3 id="支持的类型">支持的类型&lt;/h3>
&lt;p>在单个上游集群中存在多个主机，需要把下游客户端请求负载均衡至各个主机，以有效的利用资源，envoy 这里分为两类：全局负载均衡和分布式负载均衡。&lt;/p>
&lt;ul>
&lt;li>分布式负载均衡&lt;/li>
&lt;/ul>
&lt;p>是指 Envoy 根据上游主机的位置来确定如何将负载分配给端点。&lt;/p>
&lt;p>在这种策略下，Envoy 可以根据上游主机的位置信息做出更智能的负载均衡决策。&lt;/p>
&lt;p>这通常包括考虑主机的地理位置、网络延迟等因素，以优化流量的分发。这种方式使Envoy能够更好地适应不同主机之间的差异，提高系统的性能和稳定性。&lt;/p>
&lt;p>激活的健康检查（Active health checking）：通过对上游主机进行健康检查，Envoy可以调整优先级和本地性的权重，以适应不可用主机。&lt;/p>
&lt;p>区域感知路由（Zone aware routing）：这可以使Envoy在不需要在控制平面中明确配置优先级的情况下，更喜欢较近的端点。&lt;/p>
&lt;p>负载均衡算法：Envoy可以使用多种不同的算法，利用提供的权重来确定选择哪个主机。这些算法有助于更精细地控制流量的分发，以满足系统的性能和可靠性需求。&lt;/p>
&lt;ul>
&lt;li>全局负载均衡&lt;/li>
&lt;/ul>
&lt;p>是指有一个单一权威的数据来决定如何在主机之间分配负载，既控制平面完成，它可以通过指定各种参数（如优先级、本地性权重、端点权重和端点健康状况）来调整应用于单个端点的负载。&lt;/p>
&lt;p>大多数复杂的部署都会同时使用这两类特性。例如，可以使用全局负载均衡来定义高级别的路由优先级和权重，同时使用分布式负载均衡来响应系统的变化（例如，使用主动健康检查）。通过结合使用这两种方式，可以充分发挥两者的优势：在宏观层面上，可以通过一个全局意识的权威来控制流量的流向，同时在微观层面上，个体代理可以对系统变化做出反应。&lt;/p>
&lt;h3 id="策略加权轮询">策略：加权轮询&lt;/h3>
&lt;p>加权轮询（Weighted Round Robin）是一种简单的策略，它按照轮询的顺序选择每个可用的上游主机，如果在某个地区给端点分配了权重，那么将使用加权轮询的调度表，其中具有较高权重的端点将更频繁地出现在轮换中，以实现有效的加权。&lt;/p>

&lt;p>加权最小请求数（Weighted Least Request）取决于主机是否具有相同的权重，有以下区别：&lt;/p>
&lt;ol>
&lt;li>所有权重相等&lt;/li>
&lt;/ol>
&lt;p>这是一种O(1)算法，根据配置选择 N 个随机的可用主机（默认为2），然后选择具有最少活动请求的主机，权重会随着这些主机上的活动请求数量的增加而减小。&lt;/p>
&lt;ol start="2">
&lt;li>所有权重不相等&lt;/li>
&lt;/ol>
&lt;p>如果集群中多个主机具有不同的权重，负载均衡器将使用加权轮询调度表，在请求时动态调整权重，权重是在选择主机时使用以下公式计算的：&lt;/p>

&lt;h3 id="策略环形哈希">策略：环形哈希&lt;/h3>
&lt;p>环形哈希（Ring hash）实现了一致性哈希到上游主机，每个主机通过对其地址进行哈希映射到一个圆上（即由哈希组成的&amp;quot;环&amp;quot;），然后通过对请求的某个属性进行哈希，找到顺时针方向上最近的相应主机来路由每个请求。&lt;/p>
&lt;p>如果希望使用主机地址以外的其他内容作为哈希键去组成圆环，则可以在 &amp;ldquo;envoy.lb&amp;rdquo; 的 LbEndpoint.Metadata 中指定，例如：&lt;/p>

&lt;h2 id="简要概述">简要概述&lt;/h2>
&lt;p>Envoy 支持静态与动态两种配置方式，具体使用哪种根据实际情况而定。&lt;/p>
&lt;ol>
&lt;li>静态方式：由管理员预先编写好 &amp;ldquo;yaml&amp;rdquo; 文件启动；&lt;/li>
&lt;li>动态方式：由外部的 grpc 或 http 服务提供 API 接口，这些接口称为 xDS（发现服务）。&lt;/li>
&lt;/ol>
&lt;table>
&lt;thead>
&lt;tr>
&lt;th>xDS&lt;/th>
&lt;th>类型&lt;/th>
&lt;/tr>
&lt;/thead>
&lt;tbody>
&lt;tr>
&lt;td>LDS&lt;/td>
&lt;td>envoy.config.listener.v3.Listener&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>RDS&lt;/td>
&lt;td>envoy.config.route.v3.RouteConfiguration&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>x&lt;/td>
&lt;td>envoy.config.route.v3.ScopedRouteConfiguration&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>VHDS&lt;/td>
&lt;td>envoy.config.route.v3.VirtualHost&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>CDS&lt;/td>
&lt;td>[]envoy.config.cluster.v3.Cluster&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>EDS&lt;/td>
&lt;td>envoy.config.endpoint.v3.ClusterLoadAssignment&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>x&lt;/td>
&lt;td>envoy.extensions.transport_sockets.tls.v3.Secret&lt;/td>
&lt;/tr>
&lt;tr>
&lt;td>x&lt;/td>
&lt;td>envoy.service.runtime.v3.Runtime&lt;/td>
&lt;/tr>
&lt;/tbody>
&lt;/table>
&lt;h2 id="静态方式">静态方式&lt;/h2>
&lt;p>在完全静态的配置中，实施者提供一组监听器（和过滤器链）、集群等。动态主机发现仅通过基于DNS的服务发现实现。配置重载必须通过内置的热重启机制进行。&lt;/p>
&lt;p>尽管这种方式相对简单，但可以使用静态配置和优雅的热重启创建相当复杂的部署。这种方法适用于一些场景，尤其是在环境相对静态、变化不频繁的情况下。&lt;/p>
&lt;h2 id="动态方式">动态方式&lt;/h2>
&lt;h3 id="端点发现服务eds">端点发现服务(EDS)&lt;/h3>
&lt;p>端点发现服务（Endpoint Discovery Service (EDS) API），相比在静态配置中使用 DNS 实现动态主机发现，但 EDS 更灵活可自定义性强。&lt;/p>

&lt;p>基于角色的访问控制过滤器 &lt;a href="https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/security/rbac_filter">(RBAC Filter)&lt;/a> 负责验证传入请求的授权状态。该过滤器在 Envoy 进程中执行，根据预先配置的策略列表对每个请求进行检查。&lt;/p>
&lt;p>可以在以下两个地方配置过滤器：&lt;/p>
&lt;ol>
&lt;li>Network filter，当鉴权不通过则直接关闭连接；&lt;/li>
&lt;li>HTTP filter，当鉴权不通过则以 403 返回。&lt;/li>
&lt;/ol>
