Redis

How to use a Redis container?

Redis is a Key/Value storage that allows you to save data outside your database with blazing fast access. Shopware supports the usage of Redis for session and cache handling. Here is a sample of a docker setup that adds a new Redis instance to your Docker network. Just add the container and make sure its on the same network.

docker-compose.yml

version: "3"

services:
        
    shopware:
      image: dockware/play:latest
      container_name: shopware
      ports:
         - "80:80"
      networks:
         - web
      
    redis:
      image: redis:5.0.6
      container_name: redis
      networks:
        - web

networks:
  web:
    external: false

Shopware Configuration

Connection

Now make sure you configure the Redis instance to be used either for session handling, cache handling or both.

Add the following to your ".env" file:

.env (partial)

REDIS_SESSION_HOST=redis
REDIS_SESSION_PORT=6379
REDIS_CACHE_HOST=redis
REDIS_CACHE_PORT=6379

Use Redis Caches

Please note, that you also need to use it for specific parts in Shopware.
