How to use Redis 8 with ddev-redis

[apotek]

Is there an existing issue for this?

• [x] I have searched the existing issues

Is your feature request related to a problem?

Redis 7 is not fully open source.

Describe your solution

Try to use Redis 8 instead to maintain open source compat

Describe alternatives

Use a DDEV valkey add-on instead (and Valkey in QA and Prod).

Additional context

Redis 8 goes back to using a fully open source BSD license. Would you consider supporting the redis 8 docker container?

Thank you.

Hi @apotek,

The default config looks compatible for me:

ddev add-on get ddev/ddev-redis
ddev redis-backend redis:8
ddev restart

And Valkey is already supported in the same way.

TODO: Add test coverage for redis:8 and redis:8-alpine.

If you're asking us to change the default from 7 to 8, it's probably too early, I would wait for more bugfix releases.

Thank you. Yes, I agree it's probably too early. When I made the feature request, I didn't understand that the add on's docker-compose file had changed.

In the past it was:

    container_name: ddev-${DDEV_SITENAME}-redis
    image: redis:6

So I assumed we needed a redis:8 image.

Then I noticed that it could be overwritten either with a .env.redis file or other means of setting the REDIS_DOCKER_IMAGE env var.

So I was able to move forward with this in any case. Thank you for your responsiveness.
