(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
Examination revealed containerd.io this package is installed, but is version 1.2.0; it is the cause of this failure is containerd.io installation package version is too low
Solution:
1. Check Docker version, low installation version, without installing a new version Docker (this is not to introduce cumbersome installation process of a lower version)
[Root @ localhost ~] # yum list docker-ce --showduplicates | sort -r // Check the appropriate package version
[Root @ localhost ~] # yum -y install docker-ce-18.06.0.ce-3.el7 // install a lower version of the package
2. Install the new version of the package containerd.io

[Root @ localhost ~] #wget https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm // download software package
[Root @ localhost ~] # yum -y install containerd.io-1.2.6-3.3.el7.x86_64.rpm // upgrade package containerd.io
After the installation is complete reinstall Docker
[Root @ localhost ~] # yum -y install docker-ce // package mounting Docker
After the installation is complete, start Docker
[Root @ localhost ~] # systemctl start docker // CentOS7 start method
[Root @ localhost ~] #server docker start // CentOS6 start method
