Docker中有哪些常用命令

引言

Docker 是一种开源的容器化平台，允许开发者将应用程序及其依赖项打包到一个轻量级、可移植的容器中。Docker 容器可以在任何支持 Docker 的环境中运行，确保了应用程序在不同环境中的一致性。Docker 提供了丰富的命令行工具，使得开发者可以方便地管理容器、镜像、网络、数据卷等资源。

本文将详细介绍 Docker 中常用的命令，帮助读者更好地理解和使用 Docker。我们将从基础命令开始，逐步深入到镜像管理、容器管理、网络管理、数据卷管理、Docker Compose、Docker Swarm、Docker Registry、Docker 安全、Docker 系统管理、Docker 插件管理以及实验性命令等方面。
