I can install Kubernetes successfully on a Ubuntu 16 server, and get the master node into a Ready status. But if I reboot/restart, I get the error message in the title when I try to use KUBECTL.
Do I need to put the following commands given when I originally ran KUBEADM INIT into my profile to persist?
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
I was following the recipe in the O'Reilly Kubernetes Cookbook, together with using Google's K8S docs and Serverfault.
I can successfully get all the system pods running, and I can successfully get both a master and a single worker running as Ready. But they don't persist over a reboot.
