Well, got hit by this too. Ironically, I don't use docker, I think I had it installed being pulled in for something else.

So, tried the yum remove docker* but no go. When I do semanage port -a -t ssh_port_t -p tcp <port> I get an error

Bad type declaration at /etc/selinux/targeted/tmp/modules/100/docker/cil:1

which is something that doesn't exist. Tried installing container-selinux, but so far, the only way to get SSH to work on a default port is to setenforce 0.

This isn't a really important machine, but it is certainly annoying.
