I used a init.iso to set a initial password. After basic configuration is done I moved the fedora atomic vm to a live server and removed the init.iso.

1) With cloud init active boot up needs some minutes

2) Cloud init disabled kube-controller-manager won't work

Mar 02 10:59:32 atomic01 kube-controller-manager[3925]: I0302 10:59:32.103392    3925 plugins.go:70] No cloud provider specified.

Kubernetes doesn't have a cloud-init dependency, that error is an internal Kubernetes concept of cloud provider from the plugin architecture.

Fedora Atomic does have a boot "dependency" on cloud-init, meaning that having no datasource for configuration might cause longer boot times as the services run on boot.

Is the apiserver running correctly from your other question? When you moved the VM, are you setting the same IP address via DHCP in the new environment as the config files expect? How did you go about moving the VM?

So I have to mount the cloud init iso also after Fedora Atomic is configured and go live? I only need cloud init to set a password or pubkey, because there is no other way to log in... After initial config (password / pubkey, WAN network config with a static ip and default route) the atomic host was moved to production environment.

Once the host is configured there's no need for a cloud-init source, but you may see longer boot times as cloud-init still runs. The "waiting" error from kubernetes is unfortunately generic and points to something blocking before whatever kube-controller is trying to do. It could be connectivity?
