DaemonSets are special cased during host shutdown and don't get a chance to gracefully fail over. This can cause problems with both connectivity on a kill (non-grace shutdown) and sudden loss of etcd connection. Switching to a deployment will alleviate symptoms. We original chose a daemonset for spreading and for scaling. For spreading, we now have anti-affinity rules. For scaling, we should wire into something like an HPA anyway. The migration will require PRs back to 4.3 which remove the deployment on downgrade and in 4.4 to remove the daemonset.
