| 基本内容完成，可以尝试 npm start | |
| http://127.0.0.1:8080 可以正常访问 ”docker iamges inner html“ 继续 | |
| **开始构建镜像** | |
| docker build -t node-web-app:v1.0 . | |
| docker images | |
| **基本运行容器， 主要测试是否正确** | |
| sudo docker run --name test001 -d -p 3007:8080 node-web-app:v1.0 | |
| docker ps | |
| http://127.0.0.1:3007 可以正常访问 ”docker iamges inner html“ 继续 | |
| **映射宿主机运行容器** | |
| sudo docker run --name test002 -v /Users/wuxh/Documents/coder/github/example/Docker/public/build:/usr/src/app/public -d -p 3008:8080 | |
| http://127.0.0.1:3007 可以正常访问 /Users/wuxh/Documents/coder/github/example/Docker/public/build | |
| 最终目录结构 | |
|  | |
| **命令参考** | |
| // 开始构建镜像 | |
| docker build -t node-web-app:v1.0 . | |
| // 查看镜像列表 | |
| docker images | |
| // 删除不需要的镜像 | |
| docker rmi IMAGE_ID | |
| // 运行一个容器<可能需要登录 或者 sudo> | |
| sudo docker run --name test001 -d -p 6060:8080 node-web-app:v1.2 | |
| // 运行一个容器, 并将容器内部与外部映射 <可能需要登录 或者 sudo> | |
| sudo docker run --name test002 -v :/usr/src/app/public -d -p 3008:8080 node-web-app:v1.2 | |
| // 停止一个容器 | |
| docker stop IMAGE_ID | |
| // 删除不需要的容器 | |
| docker rm psname | |
| // 进入容器 | |
| docker exec -it d0ed56c70a40 /bin/bash | |
| // 导出镜像 | |
| docker save -o node-web-app.tar node-web-app:v1.2 | |
| // 导入镜像 | |
| docker load < node-web-app.tar | |
| // 查看磁盘空间 | |
| df -h | |
