Kubernetes installation on fedora meets a package conflict

Question

When I follow the kubernetes guide to install kubernetes on my local machine which runs fedora 27. I have already installed docker-ce 17.12(followed the Docker CE documentation).

bellow is the install output. is there any body can figure out what should I do to make kubernetes installed but also keep my docker-ce?

[ian@thinkpad ~]$ sudo LANG=en_US.UTF-8 dnf install kubernetes

Looks like the `kubernetes` package has a dependency over the `docker` package provided by fedora default repositories, while you installed docker-ce from an external repository. Try removing docker-ce and installing `docker` — whites11, Jan 13 '18 at 13:28
but I want to keep my docker-ce and use it with kubernetes, that is why I add this question? — Ian Hu, Jan 14 '18 at 01:18

Just requested for push of f27 update of kubernetes-1.9.1 [1] to the stable repository that allows to install either docker or docker-ce. It should take day or 2 to transit. Meantime you can install the kubernetes-node rpm from the update [1]. Tested that locally. Let me know if it does not work for you.

This is a known issue and an update is pending. Eventually, that will be in the updates set for F27 proper. In the meantime, you can get it from updates-testing, by doing:

sudo dnf --enablerepo=updates-testing install kubernetes

... and if that works for you, please add feedback on the pending update.
