POST EDITED in 2019 to reflect the current situation.

In 2018, According to the K8S documentation here.

The cluster created here has a single master, with a single etcd database running on it. This means that if the master fails, your cluster may lose data and may need to be recreated from scratch. Adding HA support (multiple etcd servers, multiple API servers, etc) to kubeadm is still a work-in-progress.

Whereas in novembr 2019 :

The cluster created here has a single control-plane node, with a single etcd database running on it. This means that if the control-plane node fails, your cluster may lose data and may need to be recreated from scratch.

Workarounds:

Regularly back up etcd. The etcd data directory configured by kubeadm is at /var/lib/etcd on the control-plane node.

Use multiple control-plane nodes by completing the HA setup instead

So, kubeadm is in 2018, kubernetes was WIP and not production ready yet. For development and testing, kubeadm should be good enough. Look here for other solutions.

In 2019, this availability issue is fixed.
