1. 前言

Envoy应该说是云原生这个概念起来之后的代理应用No.1。在当前的发展趋势下,使用Envoy来解决代理需求应该是最佳方案。

中文手册:Envoy 官方文档中文版。当前(2019-05-07)Envoy的最新版本是1.10,和中文的文档之间有几个小版本的跨度,需要注意。

2. 选型 & 比较

作为新生代的代理应用,在使用之前必然会有一个为什么的疑问,为什么需要使用Envoy,它和Nginx以及HAProxy这类老牌代理应用相比,好在哪里。

有一篇不错的博文可以阅读下:Envoy vs NGINX vs HAProxy: Why the open source Ambassador API Gateway chose Envoy。作者最主要的Concern在于两点:

  • Nginx之类的其他软件,部分有商业版本和社区版本的区分,而社区版本普遍功能较为简陋,不能完全满足需求
  • HAProxy之类的老牌软件,因为各种原因,功能演进都非常缓慢,不能跟上日益高速发展的云原生技术

说穿了就是功能不足,无论是商业原因还是研发原因还是资源原因。

那么Envoy能提供什么功能:Envoy 是什么?。可以看到Envoy提供的功能实在是太强大了,基本上现在主流的Proxy需求在Envoy身上都能得到满足。

官方也有一篇横向比较:与类似系统比较

3. Benchmark

功能之后就是性能,那么和老牌的Nginx以及HAProxy等比较起来,Envoy的性能又如何呢。这里可以看下:Benchmarking 5 Popular Load Balancers: Nginx, HAProxy, Envoy, Traefik, and ALB

Envoy came out as the overall winner in this benchmark. It had the highest throughput in terms of requests per second.

文章发布时间是:10 Dec 2018,应该说还是非常具有时效性的。

4. 架构

除了在Nginx中比较常见的作为流量入口的代理模式之外,Envoy还介绍了一种作为服务网格总线的架构模式:

这种设计将Envoy作为面向服务架构(SOA)内部的所有流量的通信总线来使用。此设计将服务和服务之间的关系遮蔽了起来,服务集群只需要知道自己的Envoy在哪里即可,后续的流量就全部交给Envoy,而Envoy之间则通过服务发现将整个服务网格链接起来。

5. 使用

5.1 镜像

一般使用镜像的方式进行安装:

docker pull envoyproxy/envoy:v1.10.0

启动:

docker run --rm -it -d \
    --name envoy-test \
    --network=envoy-test-net \
    -p 9901:9901 \
    -p 9988:9988 \
    -v ${PATH}/conf:/etc/envoy \
    -v ${PATH}/log:/tmp \
    envoyproxy/envoy:v1.10.0

镜像中配置文件的位置为:

/etc/envoy/envoy.yaml

可以通过volume进行对应的配置文件覆盖。

5.2 配置

因功能实在是太强大,Envoy的配置也就比较复杂,官方文档配置方面的总纲在:配置参考

此外,因Envoy的消息都是通过Protobuf来进行设计的,因此可以查看源代码来阅读配置项:envoy/api/envoy/config/

另外,官方代码库也给了很多配置范例:envoy/examples/。以及:几个sandbox范例:Sandbox。最适合新手查看的应该是:前端代理

有一篇Migrating from NGINX to Envoy Proxy by envoyproxy相当不错。以范例的形式讲解了Nginx的配置如何翻译到Envoy。

几个重要的配置项:

细节这里就不展开了,实在是篇幅太大。简单的范例可以直接看官方给的例子。

5.3 负载均衡Front Proxy范例

简单的带负载均衡的Front Proxy范例可以看:dist-system-practice/experiment/envoy/

踩过的几个坑:

  • 监听端的地址都必须是0.0.0.0,不能是127.0.0.1,否则在容器里收不到外部请求
  • 将其他的网络服务作为upstream使用时,必须与envoy连接在同一个docker network中
  • clusters配置中的端点地址可以使用其他docker容器的名字作为address

6. Admin

在Envoy的配置中有一个admin节点可以用来配置admin功能访问:

admin:
  access_log_path: "/tmp/admin_access.log"
  profile_path: "/tmp/envoy.prof"
  address:
    socket_address:
      address: 127.0.0.1
      port_value: 9901

提供一些admin相关功能,文档可以看:Administration interface。功能列表东西还真不少。

需要注意:

All mutations must be sent as HTTP POST operations. When a mutation is requested via GET, the request has no effect, and an HTTP 400 (Invalid Request) response is returned.

7. 监控

监控一样可以使用Prometheus进行Metrics采集。Envoy在启动的时候必须配置6. Admin,然后就可以在http://127.0.0.1:9901/stats/prometheus获取到Metrics。

本文在最后的附录部分留了一份样例:stats prometheus

8. TODO

  • Envoy的内部架构
  • Envoy的高可用设计
  • Envoy热加载的设计原理
  • Envoy的集群使用
  • Envoy的其他高级功能使用范例
  • Envoy的Metrics理解
