adrianriobo/redis-cluster-initializer repository overview

⁠redis-cluster-docker

⁠What does this solution provide

This is an implementation of a redis cluster in a dockerized environment. This project aims to solve some limitations with redis cluster in docker swarm environment

Limitations due to:

• Swarm overaly networks does not allow to fix ips⁠
• Redis cluster does not work with hostnames, so Ips are needed⁠

To avoid this issues and the needed for fixed Ips in the cluster. The containers will check its IPs and comunicate it with other nodes in the cluster.

This is a first approach to a real scalable architecture.

All nodes are fixed in the compose and scale up need some manual intervention. In future work, I will evolve to automate all the cluster management.
