kubeadm

问题 I have a K8s cluster created with kubeadm that consists of a master node and two workers. I am following this documentation article regarding the etcd backup: https://kubernetes.io/docs/tasks/administer-cluster/configure-upgrade-etcd/#backing-up-an-etcd-cluster I have to use etcdctl to backup the etcd db so I sh into the etcd pod running on the master node to do it from there: kubectl exec -it -n kube-system etcd-ip-x-x-x-x sh NOTE: The master node hosts the etcd database in this path /var

问题 We currently have 2 Kubernetes clusters: One setup with Kops running on AWS One setup with Kubeadm running on our own hardware We want to combine them to only have a single cluster to manage. The master could end up being on AWS or on our servers, both are fine.

I have initialized the cluster using 'kubeadm init --apiserver-advertise-address=172.16.100.6 --pod-network-cidr=10.244.0.0/16' and deployed the flannel network to the cluster. But when I do 'kubectl get nodes', I get the following output ---- [root@kubernetus ~]# kubectl get nodes NAME STATUS ROLES AGE VERSION kubernetus NotReady master 57m v1.12.0 Following is
