shell批量导出镜像的一个例子

目标：导出文本中的镜像，并以后缀+tar命名保存镜像，比如emqttd:v1.4.1.tar

1.txt

    image: registry.cn-hangzhou.aliyuncs.com/elements/captcha:v1.3.7
    image: registry.cn-hangzhou.aliyuncs.com/elements/statistic:v1.3.7
    image: registry.cn-hangzhou.aliyuncs.com/elements/report:v1.3.7
    image: registry.cn-hangzhou.aliyuncs.com/elements/kv:v1.3.7

执行下面命令得到镜像名文件

for x in `cat 1.txt`; do echo $x | awk -F "image:" '{print $1}' >> 2.txt; done

 

2.txt

1.sh

#/bin/bash

for x in `cat 2.txt`
do
    version_name=`echo ${x} | awk -F '/' '{print $3}'`
    tar_name=$version_name".tar"
    echo $x
    echo $tar_name
    docker save `echo $x` > `echo ${tar_name}`
done
