Mastering Kubernetes - Second Edition

Creating the etcd cluster

Save the following to etcd-cluster.yaml:

apiVersion: "etcd.database.coreos.com/v1beta2" 
kind: "EtcdCluster" 
metadata: 
  name: "etcd-cluster" 
spec: 
  size: 3 
  version: "3.2.13" 

To create the cluster type:

> k create -f etcd-cluster.yaml
etcdcluster "etcd-cluster" created
    
Let's verify the cluster pods were created properly:
> k get pods | grep etcd-cluster
etcd-cluster-0000                         1/1       Running   0          4m
etcd-cluster-0001                         1/1       Running   0          4m
etcd-cluster-0002                         1/1       Running   0          4m
