泊坞窗垃圾收集器不能做任何事情找到要删除

Question

我一直使用reg，以纪念我想从注册表中删除的斑点：

docker run --rm reg/delete -u username -p password --registry 
myregistry.com rm image 

我没有得到任何输出回来，所以我想我的标记图像删除它。

然后我跑在我的服务器的命令，我的搬运工注册表容器运行垃圾收集器，如：

 sudo docker exec -it registry bin/registry garbage- 
collect --dry-run /config/config.yml 

而且我得到了很多的输出回去就好：

，并在最后我得到这样的回顾：

12530 blobs marked, 0 blobs eligible for deletion 

因此，根据输出没有图像从我的注册表中。我通过运行df -h进行了确认，而且我仍然使用相同数量的磁盘空间。

因此，我不知道我在做什么错误，我已经按照泊坞窗文档中关于Garbage Collector的所有说明进行操作，我不知道该怎么做才能获得空间。

Answer 1

同样的问题在这里使用registry v2。

最后，我能够使用docker-distribution-pruner释放大约500GB。

只要看看注册表中的配置在容器内的

/etc/docker/registry/config.yml 

制作该文件的一个副本在主机和变化的rootdirectory路径属性为卷路径其中注册表存储图像数据。这应该是这个样子：

version: 0.1 
log: 
    fields: 
    service: registry 
storage: 
    cache: 
    blobdescriptor: inmemory 
    filesystem: 
    rootdirectory: /data/docker-registry-data/ 

然后（显然在安装该工具后）运行删减

$ sudo /home/user/bin/docker-distribution-pruner \ 
    -config=/home/user/registry-config.yml 

默认情况下，在运行模式（没有变化）上运行。当使用-delete运行时，它将通过将它们移动到 docker-backup文件夹来软删除所有数据。如有任何问题，您可以将数据移回并恢复以前的注册表状态。

如果您运行-delete -soft-delete=false，您将永远删除数据。
