#要启用垃圾回收（GC），首先要关闭Harbor服务，然后再执行清理命令

#停止Harbor相关服务

cd ./harbor
docker-compose stop

#使用–dry-run参数运行容器，预览运行效果，但不删除任何数据

docker run -it --name gc --rm --volumes-from registry vmware/registry:2.6.2-photon garbage-collect --dry-run /etc/registry/config.yml

#NOTE: The above option “–dry-run” will print the progress without removing any data.

Verify the result of the above test, then use the below commands to perform garbage collection and restart Harbor.

#不使用–dry-run参数，将删除相关的文件和镜像，

docker run -it --name gc --rm --volumes-from registry vmware/registry:2.6.2-photon garbage-collect  /etc/registry/config.yml

#重新启动Harbor相关服务

docker-compose start
