*** FATAL CONFIG FILE ERROR (Redis 6.2.2) ***
Reading the configuration file, at line 3

'sentinel monitor mymaster redis-sentinel-master-ss-0.redis-sentinel-master-ss.db.svc.cluster.local 6379 2'
Can't resolve instance hostname.

从redis-sentinel-master-ss-0 或是redis-sentinel-slave-ss-0 redis-sentinel-slave-ss-1 都可以ping通mymaster redis-sentinel-master-ss-0.redis-sentinel-master-ss.db.svc.cluster.local

尝试将redis-sentinel-configmap.yaml的哨兵配置文件修改成ip的形式 sentinel monitor mymaster ip 2
可以正常起哨兵 也可以ping通mymaster redis-sentinel-master-ss-0.redis-sentinel-master-ss.db.svc.cluster.local。

按照默认的配置，pod就是起不来，提示上面的错误Can't resolve instance hostname.
