Docker for better file systems like OVERLAYFS

Content excerpted from: http://www.projectatomic.io/blog/2015/06/notes-on-fedora-centos-and-docker-storage-drivers/

Docker sometimes reports

Either use '--storage-opt dm.thinpooldev ' or use '--storage-opt dm.no_warn_on_loop_devices=true ' to suppress this warning .

This is the file system, it's not very good.

# systemctl stop docker# rm -rf /var/lib/docker //注意好像 images可能会被清空
编辑/etc/sysconfig/docker-storage

DOCKER_STORAGE_OPTIONS= -s overlay

systemctl start docker

docker info  就可以看到改变了


备注：

overlay有较高的内核版本要求哦  反正忘4.x以上升就对了 哈
