Replace Ali Cloud Mirror Source

Wget-O / etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

Or use the NetEase mirror source (this is recommended. Recently, the Ali image source has been extracted and often cannot be accessed)

Wget-O / etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

Run yum makecache to generate cache

Solution: systemctl stop docker / / stop the docker service

Vi / etc/sysconfig/docker-storage / / change the overlay2 in the file to overlay

DOCKER_STORAGE_OPTIONS= "--storage-driver overlay"

Vi / etc/sysconfig/docker / / remove the selinux-enabled after option
