解决registry私有仓库空间清理问题
作者：楠奕
Docker Registry因历史镜像堆积导致磁盘空间不足,需定期清理,通过执行registry_garbage_collect.sh脚本及查看config.yml配置文件,可管理存储策略,释放占用空间
registry私有仓库空间清理
docker registry中堆积的历史镜像数量极多，磁盘空间告急，为此，有必要定期做镜像的清理，并释放镜像占用的存储空间。
查看脚本registry_garbage_collect.sh
# cat registry_garbage_collect.sh
#!/bin/bash
set -e
#v2仓库镜像名称
dockerConfPath=/data/install/app/registry/configyml
configFile=${dockerConfPath}/config.yml
#修改仓库属性设置为只读
ansible registry192.168.246.10 -m shell -a "sed -i '14s/enabled: false/enabled: true/' ${configFile}"
ansible registry192.168.246.11 -m shell -a "sed -i '14s/enabled: false/enabled: true/' ${configFile}"
#重启仓库组件
ansible registry192.168.246.10 -m shell -a "docker restart pro-registry"
ansible registry192.168.246.11 -m shell -a "docker restart pro-registry"
#执行仓库垃圾回收
ansible registry192.168.246.10 -m shell -a "docker exec pro-registry registry garbage-collect /etc/docker/registry/config.yml"
#修改仓库属性设置为可写
ansible registry192.168.246.10 -m shell -a "sed -i '14s/enabled: true/enabled: false/' ${configFile}"
ansible registry192.168.246.11 -m shell -a "sed -i '14s/enabled: true/enabled: false/' ${configFile}"
#重启仓库组件
ansible registry192.168.246.10 -m shell -a "docker restart pro-registry"
ansible registry192.168.246.11 -m shell -a "docker restart pro-registry"其中，246.10-11为仓库所在的主机
仓库名
pro-registry，即docker启动registry镜像时的镜像名
