# Init cluster
## For Master Node

# sudo kubeadm init --service-cidr=10.96.0.0/12 --pod-network-cidr=10.244.0.0/16 --v=6

### Copy Config
# mkdir -p $HOME/.kube
# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
# sudo chown $(id -u):$(id -g) $HOME/.kube/config

### Flannel CNI
# kubectl apply -f https://raw.githubusercontent.com/flannel-io/flannel/master/Documentation/kube-flannel.yml
### calico CNI
#kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.24.1/manifests/tigera-operator.yaml
#kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.24.1/manifests/custom-resources.yaml


### Waiting until Ready
# kubectl cluster-info
#watch -n 1 kubectl get nodes
#watch kubectl get pods -n calico-system

### Taint(if needed)
#kubectl taint nodes --all node-role.kubernetes.io/master-
# kubectl taint nodes --all node-role.kubernetes.io/control-plane- node-role.kubernetes.io/master-

# kubectl get nodes -o wide
