一、自定义custom-resources形式创建集群 
### --- 自定义custom-resources的形式创建集群
~~~     查看配置文件[root@k8s-master01 redis-cluster-operator]# more deploy/example/custom-resources.yaml
apiVersion: redis.kun/v1alpha1
kind: DistributedRedisCluster
metadata:annotations:# if your operator run as cluster-scoped, add this annotationsredis.kun/scope: cluster-scopedname: example-distributedrediscluster
spec:                           // 资源请求image: redis:5.0.4-alpinemasterSize: 3clusterReplicas: 1resources:limits:cpu: 100mmemory: 100Mirequests:cpu: 100mmemory: 100Mi
二、通过custom-resources的形式创建集群 
### --- 通过custom-resources的形式创建集群[root@k8s-master01 redis-cluster-operator]# kubectl create -f deploy/example/custom-resources.yaml
distributedrediscluster.redis.kun/example-distributedrediscluster created
三、查看service 
### --- 查看service
~~~     程序连接的redis；可以在集群的内部去路由，这个集群的片在哪个位置，是可以去路由的
~~~     所以应用程序写的地址就是这个地址[root@k8s-master01 redis-cluster-operator]# kubectl get svc
NAME                                TYPE           CLUSTER-IP       EXTERNAL-IP     PORT(S)                      AGE
example-distributedrediscluster     ClusterIP      10.100.56.42     <none>          6379/TCP,16379/TCP           27s
example-distributedrediscluster-0   ClusterIP      None             <none>          6379/TCP,16379/TCP           27s
example-distributedrediscluster-1   ClusterIP      None             <none>          6379/TCP,16379/TCP           27s
example-distributedrediscluster-2   ClusterIP      None             <none>          6379/TCP,16379/TCP           27s
example-distributedrediscluster     ClusterIP      10.100.56.42     <none>          6379/TCP,16379/TCP           62s
四、查看这个地址指向的是谁 
### --- 查看这个地址指向的是谁
~~~     可以看到这6个实例已经启动完成
~~~     -0-0：表示主节点，-0-1：表示从节点[root@k8s-master01 redis-cluster-operator]# kubectl get svc example-distributedrediscluster -oyamlredis.kun/name: example-distributedrediscluster
[root@k8s-master01 redis-cluster-operator]#  kubectl get po -l redis.kun/name=example-distributedrediscluster -owide
NAME                                      READY   STATUS    RESTARTS   AGE     IP               NODE           NOMINATED NODE   READINESS GATES
