3.镜像搜索

选择镜像建议：
1.优先选择官方的
2.选择星星多的

docker search centos

4.获取镜像

####语法：docker pull +镜像名称：版本（默认最新版本）
docker pull centos
docker pull busybox
docker pull busybox:1.29

5.查看镜像

docker images
docker image ls --no-trunc    ---查看镜像ID详细信息
docker image inspect nginx:latest 
docker image inspect bc9a0695f571（镜像ID）  --镜像详细信息查看

只查看镜像ID号：
docker images -q

6.删除镜像

docker rmi centos

7.导出镜像

docker save -o centos.tar centos:latest

8.导入镜像

docker load  < centos.tar   (#推荐使用绝对路径)
