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
