一、Redis集群一键扩容

无论数据是否持久化，操作步骤基本上是查不多的

1.1 方式一

1.修改配置文件

如果是数据持久化，需要修改persistent.yaml,将masterSize数修改为4

$ cd /root/operator-redis/deploy/example
$ vim persistent.yaml

如果是数据非持久化，需要修改persistent.yaml,将masterSize数修改为4

$ cd /root/operator-redis/deploy/example
$ vim redis.kun_v1alpha1_distributedrediscluster_cr.yaml

2.重新更新配置文件

如果是数据持久化，执行以下命令

$ cd /root/operator-redis/deploy/example
$ kubectl apply -f persistent.yaml

如果是数据非持久化，执行以下命令

$ cd /root/operator-redis/deploy/example
$ kubectl apply -f redis.kun_v1alpha1_distributedrediscluster_cr.yaml

1.2 方式二

方式二就是edit进行在线编辑

[root@k8s-master01 example]# kubectl edit  distributedrediscluster example-distributedrediscluster   -n redis-cluster

再次查看Pod，会发现创建了两个新的Pod

[root@k8s-master01 example]# kubectl get po -n redis-cluster
NAME                                      READY   STATUS    RESTARTS        AGE
drc-example-distributedrediscluster-0-0   1/1     Running   0               4h16m
drc-example-distributedrediscluster-0-1   1/1     Running   0               4h12m
drc-example-distributedrediscluster-1-0   1/1     Running   0               4h16m
drc-example-distributedrediscluster-1-1   1/1     Running   0               4h15m
drc-example-distributedrediscluster-2-0   1/1     Running   0               4h16m
drc-example-distributedrediscluster-2-1   1/1     Running   0               4h15m
drc-example-distributedrediscluster-3-0   1/1     Running   0               14m
drc-example-distributedrediscluster-3-1   1/1     Running   0               13m
redis-cluster-operator-6684799bb6-75b9l   1/1     Running   3 (4h19m ago)   4h20m

再次查看集群状态

[root@k8s-master01 example]# kubectl get distributedrediscluster -n redis-cluster
NAME                              MASTERSIZE   STATUS   AGE
example-distributedrediscluster   4                     4h22m

二、Redis集群删除

删除配置

$ cd /root/operator-redis/deploy/example
$ kubectl delete -f redis.kun_v1alpha1_distributedrediscluster_cr.yaml -n redis-cluster
$ cd /root/operator-redis/deploy/namespace
$ kubectl delete -f operator.yaml -n redis-cluster
$ kubectl delete -f role.yaml -n redis-cluster
$ kubectl delete -f role_binding.yaml -n redis-cluster
$ cd /root/operator-redis/deploy
$ kubectl delete -f service_account.yaml -n redis-cluster
$ cd /root/operator-redis/deploy/crds
$ kubectl delete -f ./

说明:上面是删除非持久化数据，如果删除持久化数据需要修改redis.kun_v1alpha1_distributedrediscluster_cr.yaml为persistent.yaml

删除命名空间

$ kubectl delete ns redis-cluster
