初始化
kubeadm init --kubernetes-version=1.18.0  --apiserver-advertise-address=0.0.0.0   --image-repository registry.aliyuncs.com/google_containers  --service-cidr=10.10.0.0/16 --pod-network-cidr=10.122.0.0/16 --ignore-preflight-errors=all
复制

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
 sudo chown $(id -u):$(id -g) $HOME/.kube/config
source <(kubectl completion bash)
kubectl get node

1.4安装网络插件

kubectl apply -f https://docs.projectcalico.org/manifests/calico.yaml

1.5安装kubernetes-dashboard

kubectl create -f recommended.yaml

1.6获取到token进行登陆

创建 token
kubectl create sa dashboard-admin -n kube-system
授权token 访问权限
kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
获取token
ADMIN_SECRET=$(kubectl get secrets -n kube-system | grep dashboard-admin | awk ‘{print $1}‘)
获取dashboard.kubeconfig 使用token 值
DASHBOARD_LOGIN_TOKEN=$(kubectl describe secret -n kube-system ${ADMIN_SECRET} | grep -E ‘^token‘ | awk ‘{print $2}‘)
echo ${DASHBOARD_LOGIN_TOKEN}
