本文介绍如何在k8s集群中使用helm来创建redis集群，供大家参考学习。
准备
- 阿里云K8S集群
- 安装helm
安装redis集群
我们首先添加一下helm库，并且搜索到redis
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm search repo redis

- 配置一：选择集群模式
通过bitnami/redis官方文档了解到，安装模式分为Master-Replicas(主副本)和Standalone(独立)，这里我们使用默认的主副本模式即可。
- 配置二：选择Service类型
bitnami/redis默认使用clusterIP模式，我们选择NodePort，为什么使用NodePort而不是clusterIP或者LoadBalance呢？因为我们本地开发环境要通过ip的方式来访问并且我们不需要负载均衡(实际上是花销太大)，另外clusterIP不支持外界访问，所以权衡之下，我们主副本都选择NodePort模式。
master:
service:
type: NodePort
replica:
service:
type: NodePort- 配置三：选择StorageClass
因为我们使用的是阿里云，所以这里我们只能使用阿里云存储，另外阿里云存储分为云盘和NAS、OSS等，因为云盘最低要20Gi我们用不到这么大的，所以我们使用NAS即可，而NAS服务要开通和创建StorageClass，这里前期我写了一篇如何创建阿里云NAS的StorageClass文章，参考上面的来操作即可创建名为alicloud-nas-fs的StorageClass，这样系统就会自动通过PVC(存储卷声明)绑定择StorageClass动态创建出PV(存储卷)。
- 配置四(可选)：配置密码
这里选择自己想要的密码即可，也可以等待创建之后，自动生成密码。
auth:
password: xxxxx配置完成之后，完整的values.yaml文件如下所示 ：
values.yaml
auth:
password: xxxxx
master:
service:
type: NodePort

type: NodePort
persistence:
storageClass: "alicloud-nas-fs"
size: 8Gi接着，我们来通过如下helm命令来创建redis集群，
$ kubectl create namespace redis
$ helm install -f values.yaml test-redis bitnami/redis --namespace redis创建成功之后，会有如下输出，
NAME: test-redis
LAST DEPLOYED: Sat Jul 17 21:56:12 2021
NAMESPACE: redis
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
** Please be patient while the chart is being deployed **
Redis(TM) can be accessed on the following DNS names from within your cluster:
test-redis-master.redis.svc.cluster.local for read/write operations (port 6379)
test-redis-replicas.redis.svc.cluster.local for read-only operations (port 6379)
To get your password run:
export REDIS_PASSWORD=$(kubectl get secret --namespace redis test-redis -o jsonpath="{.data.redis-password}" | base64 --decode)
To connect to your Redis(TM) server:
1. Run a Redis(TM) pod that you can use as a client:
kubectl run --namespace redis redis-client --restart='Never' --env REDIS_PASSWORD=$REDIS_PASSWORD --image docker.io/bitnami/redis:6.2.4-debian-10-r13 --command -- sleep infinity
Use the following command to attach to the pod:
kubectl exec --tty -i redis-client \
--namespace redis -- bash
2. Connect using the Redis(TM) CLI:
redis-cli -h test-redis-master -a $REDIS_PASSWORD
redis-cli -h test-redis-replicas -a $REDIS_PASSWORD
To connect to your database from outside the cluster execute the following commands:
export NODE_IP=$(kubectl get nodes --namespace redis -o jsonpath="{.items[0].status.addresses[0].address}")
export NODE_PORT=$(kubectl get --namespace redis -o jsonpath="{.spec.ports[0].nodePort}" services test-redis-master)
redis-cli -h $NODE_IP -p $NODE_PORT -a $REDIS_PASSWORD
这样等待redis集群的创建了，我们也可以通过命令查看是否创建成功：
$ kubectl get all -n redis
NAME READY STATUS RESTARTS AGE
pod/test-redis-master-0 1/1 Running 0 24h
pod/test-redis-replicas-0 1/1 Running 1 24h
pod/test-redis-replicas-1 1/1 Running 0 24h
pod/test-redis-replicas-2 1/1 Running 0 23h
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/test-redis-headless ClusterIP None <none> 6379/TCP 24h
service/test-redis-master NodePort 172.21.0.201 <none> 6379:30676/TCP 24h
service/test-redis-replicas NodePort 172.21.6.241 <none> 6379:32112/TCP 24h
NAME READY AGE
statefulset.apps/test-redis-master 1/1 24h
statefulset.apps/test-redis-replicas 3/3 24h这样创建全部成功，接下来就是使用redis了。
使用Redis集群
- 1、客户端访问redis
如果外界想访问redis必须通过上面的命令获取到redis所在节点ip和NodePort对应的端口，
获取IP地址：
kubectl get nodes --namespace redis -o jsonpath="{.items[0].status.addresses[0].address}"获取端口：
kubectl get --namespace redis -o jsonpath="{.spec.ports[0].nodePort}" services test-redis-master获取取ip和port之后，我们通过redis客户端即可创建新连接，如下所示：
- 2、springboot访问redis
springboot访问redis也是跟上面一样获取到ip和port，在application.yml文件中配置如下：
application.yml
spring:
redis:
database: 0
host: xx.xx.xx.xx
port: xxxxx
password: xxxxxxxx
timeout: 1000
jedis:
pool:
max-active: 8
max-wait: -1
max-idle: 8
min-idle: 0删除
如果想删除，直接到阿里云的后台选择helm应用点击删除即可
记得还要把PVC也要删除，否则一直在记费。
总结
1、使用helm安装redis集群非常方便
2、如果想开发本地访问，可以配置service使用NodePort类型，如果是生产首选默认的ClusterIP模式
3、因为阿里云云盘最低要求20G，而我们不需要这么大的，所以使用NAS更划算(有钱当我没说)
