Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker.
Enabling Redis in OL¶
Our default configuration uses file system cache. If you want to use redis you have to change symfony configuration and build own docker images.
Open config/packages/prod/config.yaml and uncomment snc_redis and framework sections.
Make sure that working redis instance is listening on host and port defined in Symfony config.
