Kubernetes Redis rejson持久化数据未保存

Question

我正在使用https://hub.docker.com/r/redislabs/rejson/

apiVersion: v1
kind: Service
metadata:
  name: redis
spec:
  ports:
    - port: 6379
      name: redis
  clusterIP: None
  selector:
    app: redis
---
apiVersion: apps/v1beta2
kind: StatefulSet
metadata:
  name: redis
spec:
  selector:
    matchLabels:
      app: redis  
  serviceName: redis
  replicas: 1
  template:
    metadata:
      labels:
        app: redis 
    spec:
      containers:
        - name: redis
          image: redislabs/rejson
          args: ["--requirepass", "pass", "--appendonly", "yes", "--save", "900", "1", "--save", "30", "2"]
          ports:
            - containerPort: 6379
              name: redis
          volumeMounts:
            - name: redis-volume
              mountPath: /data
  volumeClaimTemplates:
  - metadata:
      name: redis-volume
    spec:
      accessModes: [ "ReadWriteOnce" ]
      resources:
        requests:
          storage: 1Gi

我将arg传递给kubernetes config，以便使用"--appendonly", "yes"持久化数据存储

如果我没有通过arg，它运行的是

`redis-cli:6379 > JSON.SET foo . '"bar"'`
OK

如果我将arg传递给kubernetes config，它将生成错误，并且redis中的json模块无法工作

`redis-cli:6379 > JSON.SET foo . '"bar"'`
(error) ERR unknown command `JSON.SET`, with args beginning with: `foo`, `.`, `"bar"`,

redislabs/rejson镜像还需要将loadmodule开关作为CMD参数-这应该是可行的：

...
      args: ["--requirepass", "pass", "--appendonly", "yes", "--save", "900", "1", "--save", "30", "2", "--loadmodule", "/usr/lib/redis/modules/rejson.so"]
...
