国内用户必看】用Lima在macOS免费搭建Docker环境，彻底解决镜像与收费难题！

为了在不同操作系统有一致操作体验，我选择使用docker技术安装ollama，这样子还有一个好处，即使玩坏了，删除重建即可，所以首先需要在开发机上安装docker，从2024年开始在国内使用docker难度越来越大，主要有2大原因：

docker开始收费了，办公电脑公司不让在安装docker桌面版了
docker国内镜像一夜之间都不能用了，docker官方镜像在国内也是无法访问的

下面是在 macOS 上使用 limactl 安装和配置 Docker 的完整步骤。这个方法比 Docker Desktop 更轻量且完全免费。

准备工作

确保你的 macOS 系统已更新到较新版本
确保已安装 Homebrew（macOS 包管理器）

lima&docker安装步骤

步骤 1: 安装 Lima

打开终端（Terminal），执行以下命令：

# 使用 Homebrew 安装 Lima
brew install lima# 验证安装是否成功
limactl --version

步骤 2: 启动 Docker 实例

Lima 使用模板来创建预配置的虚拟机。我们将使用官方提供的 Docker 模板：

# 创建并启动一个名为 "docker" 的实例（使用非root用户模式，推荐）
limactl start --name=docker template://docker

注：除了可以使用官方模板也可以自定义配置文件，启动命令&配置文件&执行过程日志示例如下

# 与上面的命令 limactl start --name=docker template://docker 二选一执行即可
limactl start  ~/work/docker/lima-default.yaml

这个过程会：

下载 Ubuntu 基础镜像
在虚拟机内自动安装 Docker、Docker Compose 和其他相关工具
配置文件共享和端口转发
可能需要几分钟时间，取决于你的网络速度

步骤 3: 配置 Shell 环境

安装完成后，需要设置环境变量，让 macOS 上的 Docker CLI 能够与 Lima 虚拟机中的 Docker 引擎通信：

# 将以下行添加到你的 shell 配置文件（~/.zshrc 或 ~/.bash_profile）
echo 'export DOCKER_HOST="unix://${HOME}/.lima/docker/sock/docker.sock"' >> ~/.bash_profile# 使配置生效
source ~/.bash_profile

步骤 4: 验证安装

测试 Docker 是否正常工作：


# 检查 Docker 版本
docker --version# 运行测试容器
docker run --rm hello-world# 查看 Docker 系统信息
docker info

如果这些命令都能正常执行并返回信息，而没有报错说无法连接到 Docker 守护进程，那么就说明您的 Shell 环境已经配置成功！
