docker 手动清理私有仓库的方法
1.关于删除私有仓库的镜像，官网说明如下：
官网上注明可以通过name和digest删除image。name我们是知道的。我们只要获取digest就可以了！
查看所有镜像：
查看指定镜像：
2.registry启动依赖config.yml配置文件：在默认文件的storage区域中添加delete_enable_ture配置项（默认不添加）。也可以在启动时候指定-e添加。允许删除镜像：
下图是仓库磁盘使用情况：
3.获取某个镜像（如api-service服务）的digest(需要进入私有仓库容器，参考上一步)(没有清理的仓库，历史镜像有很多)：
4.删除镜像（接上一步）（用awk拼接出删除镜像的URL，然后批量执行）：
/var/lib/registry/docker/registry/v2 # ls -l repositories/api-service/_manifests/tags/0.0.1-SNAPSHOT/index/sha256/|grep -v "total 0"|awk '{print"curl -I -X DELETE https://sxxh-docker001.lo:5000/v2/api-service/manifests/sha256:"$9}'
curl -I -X DELETE https://sxxh-docker001.lo:5000/v2/api-service/manifests/sha256:001b7aac44f7879861eaa310375d339ae28801e8c3784ab229a04880789b3030
curl -I -X DELETE https://sxxh-docker001.lo:5000/v2/api-service/manifests/sha256:008e0311afc9842aa5968c309fade709f84f19e1e1b4f740679fbc2c0f07a422
curl -I -X DELETE https://sxxh-docker001.lo:5000/v2/api-service/manifests/sha256:04b41e1d6af713ebc13f219c39ba8e9c6c10896e7f80ce33301ee58152019aa7
curl -I -X DELETE https://sxxh-docker001.lo:5000/v2/api-service/manifests/sha256:04b6e9563f6b2f0acd337c2c2baf1a068eaadaf0dcfae77a1779ee8ed47da3d4
curl -I -X DELETE https://sxxh-docker001.lo:5000/v2/api-service/manifests/sha256:04efcac51201b2d5d2fda9fbac5e4865662495bbe7ac10d3056d0102a4cfa78a
curl -I -X DELETE https://sxxh-docker001.lo:5000/v2/api-service/manifests/sha256:06c019b03712670db4943a20a4b765de0d99002193c4160550ceca64d6333c72
curl -I -X DELETE https://scxxh-docker001.lo:5000/v2/api-service/manifests/sha256:085bca22b063f7ac0615f6c6154f960da35d4ceb5236f74e741271f3288d73a7
如上图，删除成功！
5.上面步骤只是删除了image的元数据信息（索引）。现在进入registry中进行垃圾回收命令如下：
registry garbage-collect /etc/docker/registry/config.yml
删除结果如下（部分）：
6.其他：获取digest也可以使用其他方法（但是如果历史镜像很多，显示貌似有问题，没仔细研究）。如下：
