Running the command 'kubectl -f create etcd-cluster-cr.yaml' doesn't seem to start up the cluster. Is there a step missing for k8s V1.20? I can see that the operator is running : vagrant@k8s-master:~/op-book/chapters/ch03$ kubectl create -f etcd-cluster-cr.yaml etcdcluster.etcd.database.coreos.com/example-etcd-cluster created vagrant@k8s-master:~/op-book/chapters/ch03$ kubectl get pods NAME READY STATUS RESTARTS AGE etcd-operator-bf56bb648-gq2mp 1/1 Running 0 20m hello-node-7567d9fdc9-5d977 1/1 Running 5 4d22h vagrant@k8s-master:~/op-book/chapters/ch03$ kubectl get pods -A -o wide NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES default etcd-operator-bf56bb648-gq2mp 1/1 Running 0 25m 192.168.84.138 node-1 <none> <none> default hello-node-7567d9fdc9-5d977 1/1 Running 5 4d22h 192.168.247.12 node-2 <none> <none> kube-system calico-kube-controllers-69496d8b75-fz62s 1/1 Running 8 6d19h 192.168.235.223 k8s-master <none> <none> kube-system calico-node-524tn 1/1 Running 15 6d19h 192.168.50.10 k8s-master <none> <none> kube-system calico-node-jgg47 1/1 Running 12 6d18h 192.168.50.11 node-1 <none> <none> kube-system calico-node-mxhtn 1/1 Running 12 6d18h 192.168.50.12 node-2 <none> <none> kube-system coredns-74ff55c5b-5tgw9 1/1 Running 8 6d19h 192.168.235.225 k8s-master <none> <none> kube-system coredns-74ff55c5b-bm9bw 1/1 Running 8 6d19h 192.168.235.224 k8s-master <none> <none> kube-system etcd-k8s-master 1/1 Running 9 6d19h 192.168.50.10 k8s-master <none> <none> kube-system kube-apiserver-k8s-master 1/1 Running 11 6d19h 192.168.50.10 k8s-master <none> <none> kube-system kube-controller-manager-k8s-master 1/1 Running 12 6d19h 192.168.50.10 k8s-master <none> <none> kube-system kube-proxy-ccjj6 1/1 Running 9 6d19h 192.168.50.10 k8s-master <none> <none> kube-system kube-proxy-f2fgn 1/1 Running 8 6d18h 192.168.50.11 node-1 <none> <none> kube-system kube-proxy-lp2j5 1/1 Running 9 6d18h 192.168.50.12 node-2 <none> <none> kube-system kube-scheduler-k8s-master 1/1 Running 12 6d19h 192.168.50.10 k8s-master <none> <none> kubernetes-dashboard dashboard-metrics-scraper-79c5968bdc-4b26w 1/1 Running 3 4d2h 192.168.84.137 node-1 <none> <none> kubernetes-dashboard kubernetes-dashboard-5bf9fcbd4d-cbrn5 1/1 Running 3 4d2h 192.168.235.226 k8s-master <none> <none> vagrant@k8s-master:~/op-book/chapters/ch03$ kubectl version Client Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.4", GitCommit:"e87da0bd6e03ec3fea7933c4b5263d151aafd07c", GitTreeState:"clean", BuildDate:"2021-02-18T16:12:00Z", GoVersion:"go1.15.8", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.4", GitCommit:"e87da0bd6e03ec3fea7933c4b5263d151aafd07c", GitTreeState:"clean", BuildDate:"2021-02-18T16:03:00Z", GoVersion:"go1.15.8", Compiler:"gc", Platform:"linux/amd64"} vagrant@k8s-master:~/op-book/chapters/ch03$
