if we have k8s watch the redis nodes and expose master service directly, then why we still need sentinels? #671

Expected behaviour

remove sentinels by some configurations.

What do you want to achieve?

Actual behaviour

even if I set sentinel to a number of 0, there will still be sentinels.

If you don't use sentinels, then when the master fails and can't be recovered, then no failover is triggered, and the remaining slaves don't become masters.

@wusendong great thanks for your help. the problem is that when I want to expose redis service to the outside of the k8s cluster, if I use sentinels, the master IP which sentinels report could not be accessed from the outside of the k8s cluster, because it's a intranet IP, e.g. 10.43.0.0/24
