  • Checked that there is not already provided the described functionality

Description

This role configures the cluster using the IP addresses of the nodes. However, since this role installs Redis version 7.2.3 by default, and given that Redis release 7.0 introduced support for using hostnames during cluster creation, it would be great to have an option for creating clusters using hostnames.

Expected behavior: The cluster can be created using the hostnames of the nodes.
Actual behavior: The cluster can only be created using the IP addresses of the nodes.

Additional info

You could refer to the cluster-announce-hostname option introduced in Redis 7.0, as documented on redis.io.
