Helm部署Redis-cluster

本文安装 Redis 3主3

helm包 redis-cluster-7.5.0
镜像版本 redis-cluster:6.2.6-debian-10-r193

[root@k8s-master-node1 redis-cluster]# vim /etc/exports
/redis *(sync,rw,no_root_squash)

[root@k8s-master-node1 redis]# exportfs -r
[root@k8s-master-node1 redis]# systemctl restart nfs
[root@k8s-master-node1 redis]# showmount -e
Export list for k8s-master-node1:
/redis *

创建sc

[root@k8s-master-node1 redis-cluster]# cat sc.yaml 
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: redis
provisioner: redis

创建pv

创建6个文件夹  为创建pv做准备
[root@k8s-master-node1 redis-cluster]#  mkdir -p /resid/redis{1..6}

helm里面写的用户是1001所以要给1001用户权限
[root@k8s-master-node1 redis-cluster]# chown -R 1001:root /redis

[root@k8s-master-node1 redis-cluster]# cat pv.yaml

修改vim values.yaml文件

global:
  imageRegistry: ""
  ## E.g.
  ## imagePullSecrets:
  ##   - myRegistryKeySecretName
  ##
  imagePullSecrets: []
  #设置存储类名字
  storageClass: "redis"
  #设置redis密码
  redis:
    password: "123456"

[root@k8s-master-node1 redis-cluster]# helm install redis ./

等待1分钟检测集群是否正常

[root@k8s-master-node1 redis-cluster]# kubectl exec statefulset/redis-redis-cluster -- redis-cli -h 127.0.0.1 -a 123456 cluster info
