I am passing arg to kubernetes config for persistense data store with "--appendonly", "yes"

if i am not passing arg it is running with

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

if i pass arg to kubernetes config it is generating error and json module in redis not working

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