Check your current kernel version with the uname-r command

$uname-r

2. Log in to Centos with root permission. Make sure the yum package is up to date.

$sudo yum update

3. Uninstall the old version (if the old version is installed)

$sudo yum remove docker docker-common docker-selinux docker-engine

$yum list docker-ce-- showduplicates | sort-r
