When I use Clue\React\Redis\Factory

$factory = new Factory($loop);
$factory->createClient('redis_docker_aliase')
->then(....
...

I see error

I think that this is react/dns issue.

Thanks for spotting and reporting!

This actually depends on an upstream component (react/socket-client) and there's little we can do about this here. I've filed a relevant ticket here: reactphp-legacy/socket-client#35

Small progress update: This has been fixed via reactphp/dns#75 and reactphp/socket#112 last month. So if you update your dependencies, this should now work out of the box 👍

However, I've marked this for the v2.1.0 milestone, as reliably requiring this feature here requires the switch to the Socket component first, which is a BC break targeted for the v2.0.0 release (see #50).
