Docker 镜像批量导入导出脚本
docker 批量导出镜像的sh文件，export-images.sh
#导出全部的镜像；sh export-img.sh#导出部分镜像LIST=“ d235b 201c7a 201c7a”sh export-img.sh注意：LIST赋值Docker Images ID ,多个镜像ID通过空格隔离；执行脚本是只会导出定义ID的镜像

docker 批量导入镜像的sh文件
支持传参数导入# 注意：多个tar文件使用空格分隔;sh import.sh "nacos.tar redis.tar"
支持脚本定义导入镜像名称
vi import.shSTATE="ImgName1 ImgName2 ImgName3 ...."sh import.sh
支持指定目录导入镜像
vi import.shTARDIR="/usr/local/bak"sh import.sh
支持镜像导入前备份当前镜像
# 注意：需要备份时输入字母Y，不区分大小写，不需要备份没有严格的指定，# 只要不是字母Y都可以作为否定备份；# 如果同时在脚本中指定导入镜像，又在指定脚本时指定导入镜像名称，# 默认使用以脚本定义导入镜像名称;sh import.shWhether to backup the current images[y/n]:[y/Y]
