# 第五章 操作容器

容器是 Docker 又一核心概念。

简单的说，容器是独立运行的一个或一组应用，以及它们的运行态环境。对应的，虚拟机可以理解为模拟运行的一整套操作系统 (提供了运行态环境和其他系统环境) 和跑在上面的应用。

本章将具体介绍如何来管理一个容器，包括创建、启动和停止等。

## 版本号说明

本章示例涉及多个 Docker 镜像，遵循以下版本号最佳实践：

* **官方镜像**（如 `ubuntu`、`nginx`、`mysql`）：使用具体大版本号（如 `ubuntu:24.04`、`mysql:8.4`）而非 `latest`，确保示例的可重复性
* **镜像标签约定**：
  * `latest` 或 `v1.0.0` 等：带标签的自定义镜像，示例中指定具体版本
  * `24.04`、`8.4`：官方镜像的稳定版本分支
  * 生产环境建议：指定���确版本号（如 `nginx:1.30.0`、`mysql:8.4.4`）而非仅大版本号
* [启动容器](/docker_practice/di-yi-bu-fen-ru-men-pian/05_container/5.1_run.md)
* [守护态运行](/docker_practice/di-yi-bu-fen-ru-men-pian/05_container/5.2_daemon.md)
* [终止容器](/docker_practice/di-yi-bu-fen-ru-men-pian/05_container/5.3_stop.md)
* [进入容器](/docker_practice/di-yi-bu-fen-ru-men-pian/05_container/5.4_attach_exec.md)
* [导出和导入容器](/docker_practice/di-yi-bu-fen-ru-men-pian/05_container/5.5_import_export.md)
* [删除容器](/docker_practice/di-yi-bu-fen-ru-men-pian/05_container/5.6_rm.md)
