I noticed you’re simply scaling redis without any special cluster configuration.

Hello, you’r totally right. The default configuration is used here but it would need some sync between the redis instances. I’ve tested this approach with mongo some times ago using several services https://medium.com/lucjuggery/mongodb-replica-set-on-swarm-mode-45d66bc9245 I’m not sure the sync can be done between the replicas of a same service though. What do you think ?
