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.
