Docker Registry（包括 Harbor）默認(rèn)沒有可以直觀查看使用空間的工具，registry-du 這個工具就可以用來統(tǒng)計 Registry 的 Project 空間占用。例如：

安裝

pip3 install registry-du

用法

registry-du /path/to/registry/docker/registry/v2

示例

?  registry-du /home/X/du-demo/registry/data/docker/registry/v2

Registry Path is: /home/X/du-demo/registry/data/docker/registry/v2
