ddev-redis-7 - Redis 7 container for DDEV

This repository provides Redis 7 container for DDEV.

It is based on redis:7.2-alpine docker image and DDEV custom compose files

Comparison to v6 (ddev/ddev-redis)

There are a lot of differences between v6 addon and this one

Feature	ddev/ddev-redis	ddev/ddev-redis-7
Maximum Memory	Unlimited	512Mb
Persistence	Optional	Yes
Redis Version	6.x.y	7.2.x
Image Size	~40Mb	~11Mb
Anonymous Volumes	No	No
Optimized config	No	Yes

Anonymous volumes - Wait, what?

Official redis docker container mounts an anonymous volume on /data because... reasons. That volume is recreated on every restart. This one mounts the persistence directory on /data and names it according to the project name, and gives it a proper label. This way, each DDEV project has it's own data volume, and data can persist accordingly

Persistence?

Yes, persistence. This container is configured to persist data on /data volume. This means that if you stop the container, and start it again, the data will be there. This is useful for long-term caching of data, and for keeping the cache primed between ddev restarts.

Installation

For DDEV v1.23.5 or above run

ddev add-on get ddev/ddev-redis-7

For earlier versions of DDEV run

ddev get ddev/ddev-redis-7

Then restart your project

ddev restart

Important

Authentication is setup by default, and the password is redis.
If needed, you can auth with a username and password.
Username is redis as well.

Configuration

Redis configuration files are split in the .ddev/redis/conf folder, you can modify them as you wish.
Otherwise, plugin just works out of the box.
