I am trying to setup first master node using K8s 1.10 on RHEL 7.2.
docker is running and no containers are running yet. etcd is not running either in the system. #kubeadm init command hangs. I confirmed that cgroup driver is same as that of Docker 17.06 = systemd. My system ip address is: 10.12.150.63 kubelet is started and kubelet complains where connection is refused to 10.12.150.63:6443. cat /etc/hosts 127.0.0.1 localhost ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 cat /etc/resolv.conf ; generated by /usr/sbin/dhclient-script search domain_bar I see similar symptoms at https://github.com/kubernetes/kubeadm/issues/228 I already read through below similar issues, but no success with it yet. https://github.com/kubernetes/kubernetes/issues/57870 https://github.com/kubernetes/kubernetes/issues/57709 [root@host_foo k8s]# kubeadm init [init] Using Kubernetes version: v1.10.1 [init] Using Authorization modes: [Node RBAC] [preflight] Running pre-flight checks.
