Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
You should now deploy a pod network to the cluster. Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at: https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
#查看是否运行： root@k8s-master:~# kubectl get pods -n tigera-operator NAME READY STATUS RESTARTS AGE tigera-operator-89c775547-xmrnt 0/1 ContainerCreating 0 20s
wget https://raw.githubusercontent.com/projectcalico/calico/v3.28.2/manifests/custom-resources.yaml # 注我们在kubeadm-config.yaml文件中添加的pod网段是10.244.0.0/16所以我们要修改为一样的 vim custom-resources.yaml
#应用配置 kubectl create -f custom-resources.yaml
