欢迎来到这门专为初学者和开发者设计的 Docker 完整教程!无论你是想简化开发环境、部署AI应用,还是希望系统性地掌握容器化技术,这个视频都将是你最好的向导。 本教程将从最基础的概念讲起,通过通俗易懂的比喻和层层递进的实战操作,带你一步步征服 Docker。我们将从安装配置开始,到运行第一个 Nginx 容器,再到使用 Docker Compose 编排复杂的 AI 应用(Ollama + Open WebUI),最后亲手构建一个高效、精简的自定义镜像。 你将在这门课程中学到: ✅ Docker 核心概念: 什么是容器、镜像、容器化,以及它们如何解决跨平台和环境依赖的痛点。 ✅ Docker 安装与配置: 在 Windows 系统下(基于WSL2)的完整安装流程,包括汉化、配置镜像加速器/代理。 ✅ 容器全生命周期管理: 掌握 run, ps, stop, start, rm 等核心命令,轻松管理你的容器。 ✅ 容器数据持久化: 深入理解并实战两种最重要的数据存储方式:目录挂载 (Bind Mounts) 和数据卷 (Volume),确保你的数据安全不丢失。 ✅ 多容器协同工作: 学习 Docker 网络,让不同容器(如前端和后端AI服务)之间可以高效通信。 ✅ Docker Compose: 告别繁琐的命令行!使用 compose.yaml 文件一键启动、管理和编排复杂的多容器应用。 ✅ Dockerfile 与镜像构建: 从零开始编写 Dockerfile,学习镜像分层与缓存机制,并利用多阶段构建(Multi-stage Builds)打造出属于你自己的、轻量化的生产级镜像。 无论你是后端开发者、数据科学家,还是运维工程师,掌握 Docker 都将是提升你工作效率和技术深度的关键一步。准备好进入容器化的世界了吗?让我们开始吧! 00:00:00 - P1: Docker 介绍与安装 Docker 是什么?核心优势:跨平台与隔离性 在 Windows 上安装 Docker Desktop 配置汉化包与国内镜像源 00:06:27 - P2: 运行你的第一个容器 (Nginx) 使用命令行搜索、拉取、管理镜像 (search, pull, rmi) docker run 详解:端口映射、后台运行、容器命名 查看、停止、启动和删除容器 (ps, stop, start, rm) 00:14:40 - P3: 进入容器内部:交互与调试 docker exec 命令:在运行中的容器内执行命令 进入容器交互式终端 (-it) 实战:修改 Nginx 欢迎页面 00:22:23 - P4: 数据持久化:卷(Volume)与目录挂载 为何需要数据持久化? 目录挂载 (Bind Mounts) 的使用与特性 数据卷 (Volume) 的优势与使用场景 两种方式的核心区别与选择建议 00:29:14 - P5: 更强大的挂载方式 --mount --mount 参数的清晰语法 了解 tmpfs 内存挂载 00:33:27 - P6: 容器网络与多容器协作 实战场景:部署 Ollama + Open WebUI (AI应用) 创建自定义网络 (docker network) 使用容器名进行内部服务通信 通过环境变量 (-e) 配置容器间依赖关系 00:45:11 - P7: Docker Compose - 多容器编排神器 什么是 Docker Compose? 编写 compose.yaml 配置文件 核心指令详解:services, networks, volumes, depends_on 一键启停应用 (up, down, ps, logs) 使用 .env 文件管理环境变量 00:57:43 - P8: 容器的生命周期:ENTRYPOINT 与 CMD 揭秘容器启动时执行的命令 ENTRYPOINT 与 CMD 的区别与组合使用方式 如何在启动时覆盖默认命令 01:05:24 - P9: 终极奥义:构建自己的镜像 (Dockerfile) 方法一:docker commit (快速但不推荐) 方法二:使用 Dockerfile (专业、可复现) Dockerfile 核心指令 (FROM, RUN, COPY, WORKDIR 等) 理解镜像分层与缓存机制,优化构建速度 多阶段构建 (Multi-stage Builds):打造极致精简的生产镜像
