What's the difference when installing docker with 2 of these following command? -

when comes install docker on centos, found 2 different ways it.

the first 1 : yum install docker-engine

the second 1 is: yum install docker-io

and in case installed docker using first one, continue second 1 error appeared, this:

error: docker-engine conflicts docker-1.8.2-10.el7.centos.x86_64 error: docker-engine-selinux conflicts docker-selinux-1.8.2-10.el7.centos.x86_64

so can tell me what's difference between them?

this dates from june 2015, when docker announced "new apt , yum repos"

that when new packages (like 1 centos) named docker-engine (initially replace lxc-docker*)
