<p>Hey guys.</p> <p>I'm currently learning and applying Go for a new project at my work.</p> <p>I've checked the Trending repositories in Github but I figured it would be worth a shot to ask the Reddit community for any open-source projects that a beginner could get into.</p> <p>Anyone ha...阅读全文
最近发现了一个 golang 开发的 HTTP server，叫做 Caddy，它配置起来十分简便，甚至可以 28 秒配置好一个支持 http2 的 server ，而且对各种 http 新特性都支持的比较早（比如 http2、quic都有支持）。 安装 用过 golang 的应该都知道，golang 程序基本上不会有各种依赖，都是光秃秃一个可执行程序，cp 到 /usr/local/bin就算安装完成了，所以说安装 caddy 是很简单的，我给出三种方法。 脚本安装 curl -s https://getcaddy.com | bash caddy 官方给出了一个安装脚本，执行上面的命令就可以一键安装 caddy，等执行结束后，使用 which caddy，可以看到 caddy 已经被安装...阅读全文

Caddy 源码全解析 Preface Caddy 是 Go 语言构建的轻量配置化服务器。同时代码结构由于 Go 语言的轻便简洁，比较易读，推荐学弟学妹学习 Go 的时候也去查看追一下它的源码。不用怕相信这篇文章能给你很大的信心。 可能会有点多，建议多看几遍。 Overview-CaddyMain 当然，建议看这篇文章的时候，查看上手一下 Caddy 的实际配置操作应用，对理解源码会有好处，如果没有操作过也没有关系。 Package 这是 caddy 包的结构 首先我们从一切的开始讲起，即平时我们程序运行的 main.go 函数。这是 上图 caddy 文件夹下的目录结构。在 caddy 文件夹中的 main 函数启动 caddy 服务器。实际运行的是 run.go 中的文件，这是方便测试使...阅读全文

容器非常适合封装软件，但是有时一味地改造容器镜像以使其尽可能小时，您可能走得太远。我们需要在“简洁”的镜像和无法调试的镜像之间找到很好的平衡。 看到人们调试正在运行的容器的正常方法是docker exec -it $ CONTAINER sh并根据需要在容器中安装调试工具。但是，如果您的容器没有/ bin / sh怎么办？如果没有包管理器怎么办？您可以使用docker cp将实用程序复制到容器中，然后将exec复制到正在运行的容器中，但这也很麻烦。 因此，一个朋友最近没有询问如何从容器中进行调试，而是询问如何从其他容器中进行调试。我没有那么聪明，所以我在网上问了很多聪明的人，并得到了很好的答复。 我们创建一个只有caddy的精简容器。 首先下载/提取caddy二进制文件 $: curl ht...阅读全文

caddy-grpc 为 caddy 添加一个 反向代理插件 项目地址：github.com/yhyddr/cadd… 前言 上一次我们学习了如何在 Caddy 中扩展自己想要的插件。博客中只提供了大致框架。这一次，我们来根据具体插件 caddy-grpc 学习。 选取它的原因是，它本身是一个独立的应用，这里把它做成了一个 Caddy 的插件。或许你有进一步理解到 Caddy 的良好设计。 插件作用 该插件的目的与Improbable-eng/grpc-web/go/grpcwebproxy目的相同，但作为 Caddy 中间件插件而不是独立的Go应用程序。 而这个项目的作用又是什么呢？ 这是一个小型反向代理，可以使用gRPC-Web协议支持现有的gRPC服务器并公开其功能，允许从浏览器中使用...阅读全文

如何为 caddy 添写自定义插件 项目地址：https://github.com/yhyddr/quicksilver/tree/master/gosample/caddy-plugin 前言 Caddy附带一个HTTP服务器，但是你可以实现其他服务器类型并将它们插入Caddy中。其他类型的服务器可以是SSH、SFTP、TCP、内部使用的其他东西等等。对于Caddy来说，服务器的概念是任何可以Listen()和Serve()的东西。这意味着什么、如何运作都取决于你。你可以自由地发挥你的创造力去使用它。那么怎样去扩展 Caddy 呢？不同的服务器类型，可以根据自己的需要定制不同的插件。我们在这里，通过添加最简单的不做任何事的插件，来熟悉如何扩展 Caddy 服务器。 Plugin for H...阅读全文
Caddy源码阅读（三）Caddyfile 解析 by Loader & Parser Preview 前文提到了 Caddy 的启动流程 和 Run 函数，现在我们顺着启动流程的第一步，读取 Caddyfile 的 源码阅读开始。 Loader 概念 可以理解为读取器。 在 caddy 中 由 Loader 执行 装载 配置文件的职能。看一下它的工作流程。 这个图来源于 plugin.go 文件 可以看到这里通过 Loader 解耦了 caddyfile 文件的读取，所以把它放在了 plugin.go 文件中，作为一个插件注册在 caddy app 中。 可以多定义 caddyfileloader 在图中由三个长方形的表示为数组 自定义的 caddyfileloader 会实现 右半部分的...阅读全文
