自动清理harbor镜像仓库脚本

自动清理harbor镜像仓库脚本

请看说明再执行，出现删除过多概不负责。

网上找的版本删除有点问题，做了一定的修改。
我这里的镜像都是依照数字正常排序构建的。例如

v:1.0.1
v:1.0.2
v:1.0.3
v:1.0.4
OLD_VERSION_NUM设置为3的话 会把v:1.0.1删除。只保留后3个。

执行前须安装jq

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum install jq -y

shell（须放到harbor主机执行）

#!/bin/bash
set -e
HARBOR_URL=harbor.test.com
HARBOR_PASSWD=123456
#最大保留镜像个数。超过后的删除。
OLD_VERSION_NUM=20
