kubernetes集群-02部署Master Node

部署Kubernetes Master

在172.16.10.11（Master）执行。

kubeadm init \
  --apiserver-advertise-address=172.16.10.11 \
  --image-repository registry.aliyuncs.com/google_containers \
  --kubernetes-version v1.18.0 \
  --service-cidr=10.96.0.0/12 \
  --pod-network-cidr=10.244.0.0/16 \
  --ignore-preflight-errors=all

由于默认拉取镜像地址k8s.gcr.io国内无法访问，这里指定阿里云镜像仓库地址。

或者使用配置文件引导：

# vim kubeadm.conf
apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: v1.18.0
imageRepository: registry.aliyuncs.com/google_containers 
networking:
  podSubnet: 10.244.0.0/16 
  serviceSubnet: 10.96.0.0/12 

# kubeadm init --config kubeadm.conf --ignore-preflight-errors=all 

To start using your cluster, you need to run the following as a regular user:

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

把node节点加入集群

把下面命令复制到node1和node2上面执行

kubeadm join 172.16.10.11:6443 --token 9neow7.n8nignhkvrfnljca \
    --discovery-token-ca-cert-hash sha256:395522c4985bc296352c74632057d3ddd2d5cf75eed1266e11e780be2ea7fd31 

Master节点查看

kubectl get node
NAME         STATUS     ROLES    AGE     VERSION
k8s-master   NotReady   master   7m21s   v1.18.0
k8s-node1    NotReady   <none>   18s     v1.18.0
k8s-node2    NotReady   <none>   6s      v1.18.0
