## 根据镜像列表文件，自动到harbor拉取镜像，并根据给出的前缀自动打tag，最后自动保存镜像为tgz文件
## 参数说明：$1表示镜像列表文件名，其组织的格式如下所示，$2表示目标tag的前缀，即repositry名，默认：registry.cluster.local:30443
## 如想将registry.dongge.cn/amd64/zookeeper:3.5.8拉下来并打上tag为registry.cluster.local:30443/zookeeper/zookeeper:3.5.8，最后保存为zookeeper_3.5.8.tgz步骤如下：
## 1. 新建一个文本文件，如repo.txt
## 2. 向新建的repo.txt文件中写入内容为：registry.dongge.cn/amd64/zookeeper:3.5.8->registry.cluster.local:30443/zookeeper/zookeeper:3.5.8
## 3. 注意：1)如果有多组镜像，每组镜像需另起一行; 2)每一组的"->"符号前后无空格；3)如果仅需要从harbor拉镜像，并使用registry.cluster.local:30443为前缀打tag，如:
## 将registry.dongge.cn/amd64/jdk:1.8.0拉下来，并打上：registry.cluster.local:30443/amd64/jdk:1.8.0，则只需在repo.txt中写registry.dongge.cn/amd64/jdk:1.8.0
## 对于第 "3)" 注意：多个镜像，每个镜像需要另起一行。4)示例文件参考repo_sample.txt


splitor='->'
repo_prefix=$2

if [ -z "$repo_prefix" ];then
  repo_prefix='registry.cluster.local:30443'
fi

while read line

do
  if [[ $line =~ $splitor && $line != \#* ]];then
    a=${line%->*}
    b=${line##*->}
    docker pull $a
    docker tag $a $b
    c=${b##*/}
    d=${c/:/_}
    docker save -o $d.tgz $b
  elif [[ $line && $line != \#* ]];then
    suffix=${line#*/}
    docker pull $line
    docker tag $line $repo_prefix/$suffix
    c=${line##*/}
    d=${c/:/_}
    docker save -o $d.tgz $line
  fi

done < $1

镜像列表文件：repo_sample.txt

##目标tag后缀与源部分一致，部分不一致的情况
## 说明：直接使用此文件经过测试可以直接在docker_pull_tag_save.sh执行
