Fedora Atomic Host 25 Getting Started Docs

[ashcrow]

The current Getting Started documentation seems like it will become out of date with upcoming changes in Fedora Atomic Host 25.

• Move towards "system containers" (or layered packages) for flannel/etcd
• Move towards containers (system, or Docker) for kubernetes-master
• Move towards layered packages for kubernetes-node and storage (ceph/gluster)

I agree. Want to start writing a replacement?

Looks like 1.3.2 at https://access.redhat.com/documentation/en/red-hat-enterprise-linux-atomic-host/7/paged/getting-started-with-kubernetes/chapter-1-get-started-orchestrating-containers-with-kubernetes is a good starting place. (noted by @miabbott)

at the very beginning of the guide, I need to run this command:

[fedora@atomic-master ~]$ sudo atomic host upgrade --reboot

but in fact I got an error:

atomic: invalid choice: 'host' (choose from 'containers', 'diff', 'help', 'images', 'in fo', 'install', 'mount', 'pull', 'push', 'upload', 'run', 'scan', 'sign', 'stop', 'stor age', 'migrate', 'top', 'trust', 'uninstall', 'unmount', 'umount', 'update', 'verify', 'version')
Try 'atomic --help' for more information.

@GongT That usually indicates you are not using Atomic Host. Can you try running rpm-ostree status and see if that works for you?
