Cant create only master nodes Cluster

[george lin]

I only have 3 vm, and I want to create 3 master nodes cluster without replica. 

It Always become 1 master and 2 slave.

my command:

redis-cli --cluster create 10.140.0.15:6379 10.140.0.16:6379 10.140.0.17:6379

Why  result Is not the same with configuration??

result: 

>>> Performing hash slots allocation on 3 nodes...

Master[0] -> Slots 0 - 5460

Master[1] -> Slots 5461 - 10922

Master[2] -> Slots 10923 - 16383

M: c3d0be42f210d7a3a443bdf33b2891c7e4633d7a 10.140.0.15:6379

   slots:[0-16383] (5461 slots) master

M: 5c0074c90de6f28aad1ecbd5723a882c989b0616 10.140.0.16:6379

   slots:[0-16383] (5462 slots) master

M: 6bc9c37eada7628588fdcb3cc5732b80592bf302 10.140.0.17:6379

   slots:[0-16383] (5461 slots) master

Can I set the above configuration? (type 'yes' to accept): yes

>>> Nodes configuration updated

>>> Assign a different config epoch to each node

>>> Sending CLUSTER MEET messages to join the cluster

Waiting for the cluster to join

..

>>> Performing Cluster Check (using node 10.140.0.15:6379)

I have tried  --cluster-replicas 0、addnode 、cluster meet and none of them is successed.
