Redis Cluster Setup with dns

Question

NOTE: I am new to redis cluster setup.

I am working setting up redis cluster. The cluster setup is complete. However when I want to setup the cluster using dns as follows

redis-cli --cluster create redis-01.internal:6379 redis-02.internal:6379 redis-03.internal:6379

I get the following errors indicating

>>> Nodes configuration updated

I did also go through few of the similar questions which suggest dns based clustering is not available in redis.

So, is there any solution or some way to make sure the dns based cluster works for redis.

Unfortunately, Redis doesn't support creating cluster by specifying hostnames; their IPs need to be used instead.
