https://account.aliyun.com/login/login.htm?oauth_callback=https%3A%2F%2Fcr.console.aliyun.com%2F&lang=zh#/accelerator

vim /etc/docker/daemon.json

}

6.harbor 删除镜像及资源回收

$ docker-compose stop
$ docker run -it --name gc --rm --volumes-from deploy_registry_1 registry:2.5.0 garbage-collect --dry-run /etc/registry/config.yml
