ClusterSize Parameter does not work

What version of redis operator are you using?

redis-operator version: redis-operator-0.15.9

Does this issue reproduce with the latest release? This is the latest helm chart I could get

What operating system and processor architecture are you using (kubectl version)?

What did you do?

• helm upgrade redis-operator ot-helm/redis-operator --install
• helm upgrade redis-cluster ot-helm/redis-cluster --set redisCluster.clusterSize=1 --install

What did you expect to see? A cluster with one leader and one failover node

What did you see instead? A cluster with three leader and three failover nodes

[wkd-woo]

I think 'clusterSize' should be the same value as 'leader.replicas' + 'follower.replicas'.

'RedisCluster' doesn't mean "a set" of Redis cluster. This means one member, as a 'Custom Resource' in itself called the 'RedisCluster'.

Try clusterSize=6.

and as you already know, redis cluster 'one set' configuration requires at least three master leaders.

[iamNoah1]

Thanks for the reply @wkd-woo. I cannot confirm that clusterSize is equal to leader.replicas + follower.replicas. It does not matter if I configure it to 1, 3 or 6, it always remains 3 leaders and 3 followers.

According to different information sources like this it should work like I expected which is when I set ClusterSize to 5 having 5 leader and 5 follower nodes. But it does not :) ...

[wkd-woo]

@iamNoah1 Oh, I understand your situation. I've been wandering around with the same problem before.

I'll give you the test manifest I'm using. I recommend override the .yaml file with '-f' rather than 'set'

helm install redis-cluster helm/chart/redis-cluster -f values.yaml
