解决docker启动错误 error creating overlay mount to /var/lib/docker/overlay2

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"

禁用selinux

vi /etc/sysconfig/docker

去掉option的–selinux-enabled

启动docker应该就可以了

systemctl start docker
