Unlike C, MATLAB, Perl, Python, and Ruby - but like Java, and a few other stricter, typed languages - it is an error if the value of a conditional expression

卸方式，换一种运输工具就要重新装卸。集装箱的出现改变了这一切：无论里面装的是什么，集装箱的外形是标准的，可以用同样的方式装卸、堆放和运输。 Docker做的事情类似：无论你的应用是用Python、Java、Node.js还是其他语言写的，无论它需要什么样的依赖库和环境，一旦被打包成Docker镜像，就可以用同样的方式在任何支持Docker的机器上运行。 1.2.2 Docker的核心价值 笔者认为 开发者：代码写完了，本地测试通过，提交！ 周一早上 9:00 测试：“这个功能在测试环境跑不起来” 开发者：“不可能，在我电脑上明明能跑啊…” 笔者统计过，这个问题通常由以下原因导致： Python/Node/Java 版本不一致 依赖库版本不一致 操作系统配置不一致 某些环境变量没有设置 “哦，忘了说我本地装了个 XXX” 场景二：环境配置的噩梦 新同事入职 Day1：领电脑，配环境 Day dockerignore、 compose.yaml 和 README.Docker.md 等文件： $ docker init 该命令会交互式地询问项目类型（支持 Go、Node.js、Python、Rust、Java、ASP.NET Core、 PHP with Apache等），并生成可作为起点的配置文件。对于新项目，这是一个很好的起步方式，但生成后的内容仍应结合项目实际情况继续调整。 4.5.2 手动创建
