}
EOF
sudo systemctl daemon-reload  // 重新加载配置
sudo systemctl restart docker // 重启docker

docker常用命令

部署前端项目

# build stage
FROM node:18 as build-stage ## 构建阶段 下载node镜像

WORKDIR /app ## 设置工作目录

COPY package.json ./ ## 复制package.json到工作目录

RUN npm config set registry https://registry.npmmirror.com/ ## 设置npm镜像源

RUN npm install ## 安装依赖包

COPY . . ## 复制项目到工作目录

RUN npm run build ## 构建项目

# production stage
FROM nginx:stable as production-stage ## 生产阶段 下载nginx镜像

COPY --from=build-stage /app/dist /usr/share/nginx/html ## 复制构建后的项目到nginx的默认目录

COPY --from=build-stage /app/nginx.conf /etc/nginx/conf.d/default.conf ## 复制nginx配置文件

EXPOSE 80 ## 暴露端口
CMD ["nginx", "-g", "daemon off;"] ## 启动nginx

nginx配置
