instead of modifying the host to add/remove the packages you want,
you can create a docker image containing whatever you want to run (even if it's the docker daemon itself)
then run that container using atomic tool with ostree/runc backend (without docker daemon)
[root laptop ~]# docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
[root laptop ~]#
[root laptop ~]# atomic run --storage ostree registry.fedoraproject.org/fedora-minimal /bin/bash
bash-4.4#
OK, I see. It is really very very powerful. I choose the other solution, running rebase, as I needed to do it anyway. Plus, all this is quite new to me (especially the Kubernetes stuff) and asks a lot of reading and work from myself. I am afraid being lost if I go too deep in the containerize affair.
TY anyway as your method will help in other situations I guess.

Not sure to fully understand. Here what I did:
------------------------
# atomic host install docker-ce-17.03.2.ce-1.el7.centos.x86_64.rpm docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm

Is it what you were talking about?
