article 2025/8/22 0:17:05

前言

本章讲解Docker常用命令之一的镜像命令

方法

1.永远的helloworld

我们知道,任何的语言和技术都有它入门的hello world。就如同我们刚开始学习java那样。

我们在什么也不清楚的时候运行我们的第一个命令：docker run hello-world观察效果如下：

这个画面代表着我们第一个docker学习的命令运行成功啦！Hello from Docker！

每当我们学习一个命令的时候，它的参数很复杂，我们可以使用命令+--help，docker也不例外。

使用命令docker --help观察docker的所有常用命令：

有点多哈，大家不要慌，本章仅仅是将基础的镜像命令哦！

2.docker的镜像命令

1）docker images命令

该命令用于列举出本地所拥有的镜像列表，使用docker images效果如下：
