class="warning"><p> <strong>相似指令区分</strong><br> 1️⃣ <strong>COPY和ADD：</strong> COPY用于将宿主机文件拷贝至容器，或者在多阶段构建时用于将上一构建阶段的文件拷贝至本阶段构建。ADD指令同样可用于拷贝文件，但是该指令可以自动解压tar包，并删除源文件。</p><p> 2️⃣ <strong>ARG和ENV：</strong> ARG指令和ENV指令的作用域不同，ARG指令指定的便令仅在镜像构建时起作用，镜像构建完成生命周期即结束。ENV指令将环境变量 <code><key></code> 设置为值 <code><value></code>将在构建阶段的所有后续指令的环境中，并且也可以在许多指令中内联替换。</p><p> 3️⃣ <strong>CMD和ENTRYPOINT：</strong> CMD指令设置从镜像运行容器时固定要执行的命令。Dockerfile中只能有一条 <code>CMD</code> 指令。如果您列出多个 <code>CMD</code> ，则只有最后一个生效。如果用户为 <code>docker run</code> 指定参数，那么他们将覆盖 <code>CMD</code> 中指定的默认值。ENTRYPOINT指令设置从镜像运行容器时要执行的命令，但用户可以为该指令传递参数，若CMD指令和ENTRYPOINT指令同时使用则CMD指令将作为ENTRYPOINT指令的参数传递。</p></div><h2 id="二、Dockerfile制作镜像">二、Dockerfile制作镜像</h2><p>1️⃣ 创建Dockerfile文件。 根据个人习惯而言，一般为了文件的可读性，我们需要先创建一个空目录，并在目录下创建Dockerfile文件，（约定俗成我们一般就以Dockerfile为名，编译时也会自动寻找这个文件，也可自定义文件名，但是我们在编译文件时需用 <code>-f</code> 指定需编译文件的绝对路径，自定义文件名语义混乱容易导致文件错落，不建议！）</p><span id="more"></span><p>2️⃣

将经常修改的指令往后放，如：RUN、COPY、ADD、CMD、ENTRYPOINT…）④ 使用".dockerignore"，忽略我们不需要参与编译的文件（如不忽略，则编译前会当前文件夹所有文件传递给docker deamon进程，但我们真正编译时用不到这些与制作镜像不相关的文件。）</p><h3 id="2、从镜像体积上说">2、从镜像体积上说</h3><p>①

<div class="warning">
<p> <strong>相似指令区分</strong><br>
1️⃣ <strong>COPY和ADD：</strong> COPY用于将宿主机文件拷贝至容器，或者在多阶段构建时用于将上一构建阶段的文件拷贝至本阶段构建。ADD指令同样可用于拷贝文件，但是该指令可以自动解压tar包，并删除源文件。</p>
<p> 2️⃣ <strong>ARG和ENV：</strong> ARG指令和ENV指令的作用域不同，ARG指令指定的便令仅在镜像构建时起作用，镜像构建完成生命周期即结束。ENV指令将环境变量 <code>&lt;key&gt;</code> 设置为值 <code>&lt;value&gt;</code>将在构建阶段的所有后续指令的环境中，并且也可以在许多指令中内联替换。</p>
<p> 3️⃣ <strong>CMD和ENTRYPOINT：</strong> CMD指令设置从镜像运行容器时固定要执行的命令。Dockerfile中只能有一条 <code>CMD</code> 指令。如果您列出多个 <code>CMD</code> ，则只有最后一个生效。如果用户为 <code>docker run</code> 指定参数，那么他们将覆盖 <code>CMD</code> 中指定的默认值。ENTRYPOINT指令设置从镜像运行容器时要执行的命令，但用户可以为该指令传递参数，若CMD指令和ENTRYPOINT指令同时使用则CMD指令将作为ENTRYPOINT指令的参数传递。</p>
</div>
<h2 id="二、Dockerfile制作镜像">二、Dockerfile制作镜像</h2>
<p>1️⃣ 创建Dockerfile文件。 根据个人习惯而言，一般为了文件的可读性，我们需要先创建一个空目录，并在目录下创建Dockerfile文件，（约定俗成我们一般就以Dockerfile为名，编译时也会自动寻找这个文件，也可自定义文件名，但是我们在编译文件时需用 <code>-f</code> 指定需编译文件的绝对路径，自定义文件名语义混乱容易导致文件错落，不建议！）</p></summary>

<div class="warning">
<p>shell中的普通数组和C的一维数组一样，但是关联数组有所不同，关联数组可以用任意的文本作为数组索引，而普通数组中的索引都是整数，且关联数组使用之前需要声明：<code>declare -A ass_array</code></p>

介绍 ：南汐的云端小铺暂时暂时只写了一个板块（今日上新），其他板块大家可自行拓展，或者南汐改天可以再完善一下，目前实现的功能有：菜单显示、商品购买、用户登录验证与注册、账户余额充值与显示、购物账单打印。细节大家可自行测试，金无足赤，人无完人，如有Bug，欢迎大家在评论区反馈，或者分享建议哦~ヾ(•ω•`)o</font><table><tr><td bgcolor=#000000><font

<blockquote>
<p>🎃 突发奇想，怎么样让大家快速的掌握编程里面的判断和循环呢，理论知识只是基础，关键在于自己的代码手感和编程的思维，无他，学习编程我们只需要记住一点：<font color=red><strong>百炼成神</strong></font>。其余，底层的原理和架构是我们高纬度的空间，天梯是不可僭越的，需要一步一步攀登！</p>

<font color="#fc5531">▚ 介绍 ：南汐的云端小铺暂时暂时只写了一个板块（今日上新），其他板块大家可自行拓展，或者南汐改天可以再完善一下，目前实现的功能有：菜单显示、商品购买、用户登录验证与注册、账户余额充值与显示、购物账单打印。细节大家可自行测试，金无足赤，人无完人，如有Bug，欢迎大家在评论区反馈，或者分享建议哦~ヾ(•ω•`)o</font>

<p>✨ Shell 这个单词的原意是“外壳”，跟 kernel（内核）相对应，比喻内核外面的一层，即用户跟内核交互的对话界面。<br>
🎉 Shell 是一个程序，提供一个与用户对话的环境。这个环境只有一个命令提示符，让用户从键盘输入命令，所以又称为命令行环境（command line interface，简写为 CLI）。<br>
🎁 Shell 是一个命令解释器，解释用户输入的命令。其次，Shell 是一个工具箱，提供了各种小工具，供用户方便地使用操作系统的功能。</p>
