作用主要目的用于批量镜像导入;
实例:
sh import.sh "pause_3.1.tar etcd_3.3.10.tar"
注意:多个tar文件使用空格分隔;
实例:
vi import.sh
STATE="ImgName1 ImgName2 ImgName3 ...."
sh import.s
实例:
vi import.sh
TARDIR="/usr/local/bak"
sh import.sh
sh import.sh
Whether to backup the current images[y/n]:[y/Y]
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;
