Which problems did you encounter? Can you be more specific? Can we solve them
for everyone else?

Since Pike, magnum is running kubernetes in containers on fedora 26.
In fedora atomic 27 kubernetes etcd and flannel are removed from the
base image so running them in containers is the only way.

For RBAC, you need 1.8 and with Pike you can get it. just by changing
one parameter.

In our private cloud at CERN we have ~120 clusters with ~450 vms, we are running
Pike and we use only the fedora atomic drivers.

Atomic is maintained and supported much more than CoreOS in magnum.
There wasn't much interest from developers for CoreOS.

Magnum Ocata is not too old but it will eventually be since it misses the
capability of running kubernetes on containers. Pike allows this option and can
keep up with kubernetes easily.

I did the project update presentation for magnum at the Sydney summit.
