参考 github

https://github.com/ucloud/redis-cluster-operator

添加repo仓库，并更新

 

helm repo add ucloud-operator https://ucloud.github.io/redis-cluster-operator/

helm repo update

 拉取redis-cluster配置信息

helm fetch ucloud-operator/redis-cluster-operator

解压 

 tar -zxvf redis-cluster-operator-0.1.0.tgz

查看配置文件所需镜像版本，拉取镜像信息

 docker pull fishu/redis-cluster-operator

拉取镜像失败，我已经将该镜像保存在我的镜像仓库，可下载

docker pull swr.cn-north-4.myhuaweicloud.com/redis/redis-cluster-operator:v0.2.4

修改镜像tag

docker tag swr.cn-north-4.myhuaweicloud.com/redis/redis-cluster-operator:v0.2.4 fishu/redis-cluster-operator:latest

helm部署redis-cluster-operator 

 helm install redis .

部署redis

这些deploy放置在https://github.com/ucloud/redis-cluster-operator/tree/master/deploy/example

以如下的deploy-redis.yaml为例：

apiVersion: redis.kun/v1alpha1
kind: DistributedRedisCluster
metadata:
  annotations:
    # if your operator run as cluster-scoped, add this annotations
    redis.kun/scope: cluster-scoped
  name: redis
spec:
  # Add fields here
  masterSize: 3
  clusterReplicas: 1
  image: redis:5.0.12
  resources:
    limits:
      cpu: 200m
      memory: 200Mi
    requests:
      cpu: 200m
      memory: 100Mi

执行：

kubectl apply -f deploy-redis.yaml

 

若提示如上报错 error: unable to recognize "deploy-redis.yaml": no matches for kind "Distributed RedisCluster" in version "redis.kun/v1alpha1"

则切到crds目录执行

kubectl apply -f redis.kun_distributedredisclusters_crd.yaml
kubectl apply -f redis.kun_redisclusterbackups_crd.yaml

切到上次目录，再次执行 

 kubectl apply -f deploy-redis.yaml

要是redis拉取不到镜像提供我仓库的镜像地址：

docker pull swr.cn-north-4.myhuaweicloud.com/redis/redis:5.0.12

修改tag

docker tag swr.cn-north-4.myhuaweicloud.com/redis/redis:5.0.12 redis:5.0.12

集群已经全部起来，pending的pod是因为资源不足导致 ，调整资源重新部署

可设置密码:创建部署 secret.yaml

apiVersion: v1
kind: Secret
metadata:
  annotations:
    # if your operator run as cluster-scoped, add this annotations
    redis.kun/scope: cluster-scoped
  name: mysecret
type: Opaque
data:
  password: MTIzNDU2
# echo -n "123456" |base64

修改deploy-redis.yaml,以及添加redis 启动config配置信息

apiVersion: redis.kun/v1alpha1
kind: DistributedRedisCluster
metadata:
  annotations:
    # if your operator run as cluster-scoped, add this annotations
    redis.kun/scope: cluster-scoped
  name: redis
spec:
  # Add fields here
  masterSize: 3
  clusterReplicas: 1
  image: redis:5.0.12
  resources:
    limits:
      cpu: 200m
      memory: 200Mi
    requests:
      cpu: 200m
      memory: 100Mi
  passwordSecret:
      name: mysecret
   config:
    appendonly: "yes"
