Hi @binary64, in trace I saw that fail appears because of pulling image problem: failed to pull image k8s.gcr.io/etcd:3.4.3-0: output: Error response from daemon: Get https://k8s.gcr.io/v2/etcd/manifests/3.4.3-0: unable to decode token response: invalid character '<' looking for beginning of value Please perform next commands to reset deployment: sudo kubeadm reset rm -rf ~/.kube sudo rm -rf /etc/kubernetes sudo rm -rf /var/lib/etcd/ echo "KUBELET_EXTRA_ARGS=" | sudo tee /etc/default/kubelet and try to execute ansible script again, if problem with pulling images reproduced please try to pull image manually and send us traceback from pull. Also, please, attach command which you use to execute ansible script.
