Re: [atomic-devel] forbidden base package replacement

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)

the same way atomic host is running etcd and flanneld without docker daemon

here is a session

[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#

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

In order to create a Kubernetes cluster, I want to downgrade docker to docker-ce-17.03.

I uninstalled successfully current docker version with some dependencies with the following command:

------------------------------
# rpm-ostree override remove cockpit-docker docker docker-common
------------------------------

Now i want to install two rpm files for docker:

-------------------------------
# rpm-ostree 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

The above command returned:

Googling, it seems this is a common issue, but I didn't find any solution. How can I solve this issue and install docker-ce & dependencies?

Regards.
