Docker-ce-selinux and Docker-selinux and Container-selinux.

When installing Dockerce 17.09, it was found that the official provided the Docker-ce-selinux package, prone to confusion, explained here

Dockerce installation Method,

wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-17.09.0.ce-1.el7.centos.x86_ 64.rpmyum localinstall-y docker-ce-17.00.0.ce-1.el7.centos.x86_64.rpm

As above, Yum will automatically install container-selinux.

Docker-ce-selinux and Docker-selinux are different distribution versions of a package.

Container-selinux is the next version of Docker-selinux.

We analyzed the RPM package found in Docker Ce 17, which abolished docker-ce-selinux and relied on container-selinux >= 2.9
