解决 error creating overlay mount to /var/lib/docker/overlay2

最近在centos7.1使用docker运行redis镜像，出现下面的错误：

ERROR: for ddns  Cannot start service ddns: error creating overlay mount to /var/lib/docker/overlay2/f861b6ba19002faade18e4c75c3772ccafcd09696acf969fab17f005cc7a6eed/merged: invalid argument

停止docker服务

systemctl stop docker

清理镜像

rm -rf /var/lib/docker

修改存储类型

vi /etc/sysconfig/docker-storage

把空的DOCKER_STORAGE_OPTIONS参数改为overlay:

DOCKER_STORAGE_OPTIONS="--storage-driver overlay"

vi /etc/sysconfig/docker

禁用selinux

方法1：

去掉option的–selinux-enabled

方法2：

永久关闭：输入命令vi /etc/selinux/config，将SELINUX=enforcing改为SELINUX=disabled，然后保存退出。

启动docker应该就可以了

systemctl start docker
