求问 这个提示怎么破 Usage of loopback devices is strongly discouraged for produc

docker run learn/tutorial  echo "hello"
Usage of loopback devices is strongly discouraged for production use. Either use `--storage-opt dm.thinpooldev` or use `--storage-opt dm.no_warn_on_loop_devices=true` to suppress this warning.
hello


求解释这是什么意思啊 并且怎么破

设置一下 /etc/sysconfig/docker-storage 中的参数：
DOCKER_STORAGE_OPTIONS="--storage-opt dm.no_warn_on_loop_devices=true"

也可能是docker 镜像有问题。
