基本操作
Kubeadm 初期化
kubeadm init --api-advertise-addresses 192.168.1.177 --use-kubernetes-version v1.5.1
織り方を適用
kubectl apply -f https://git.io/weave-kube
Kubeadm リセット
kubeadm reset docker rm `docker ps -a -q` find /var/lib/kubelet | xargs -n 1 findmnt -n -t tmpfs -o TARGET -T | uniq | xargs -r umount -v rm -r -f /etc/kubernetes /var/lib/kubelet /var/lib/etcd
