Hi @friedinando - Why don't you fork https://github.com/ddev/redis and create a new add-on using valkey. I imagine it's pretty straightforward. Another option would be a PR to make valkey an option on the redis PR.

I moved this issue to the ddev-redis add-on repo, it's worthy of conversation here.

They already have 17k stars https://github.com/valkey-io/valkey, we definitely should support Valkey.

I ran this to see what we have inside, and redis-server is available.

docker run --rm -it --name valkey valkey/valkey bash

We can replace this

ddev-redis/docker-compose.redis.yaml

Line 5 in 0147f41

image: redis:${REDIS_TAG:-6-bullseye}

with:

image: ${REDIS_IMAGE:-redis}:${REDIS_TAG:-6-bullseye} 

and update tests to check if Valkey is going to work.

But this reminds me of https://github.com/ddev/ddev-elasticsearch vs https://github.com/ddev/ddev-opensearch that already have some differences.

What if Valkey implements something new, then it's better to have a new add-on.
