| Provisioning to use Calico | |
| 1/20/2017 | |
| First, tearing down the cluster, by doing this on each node: | |
| kubeadm reset | |
| rm -rf .kube | |
| systemctl start kubelet.service | |
| Did yum -y update on all nodes as well. Downloaded http://docs.projectcalico.org/v1.6/getting-started/kubernetes/installation/hosted/kubeadm/calico.yaml and then ran "kubectl create -f calico.yaml". | |
| Starting up cluster (with just the master node). |
