Difficulty configuring Async::Job with Redis in production (works locally)

[adrienpoly]

Hello 👋

First off, thanks for this amazing gem and for the eye-opening work on Async::Job!

I’m currently running in a Puma environment. I’m not quite ready to make the full Falcon jump yet, so I’ve been trying the “mixed” approach with Puma + Async::Job.

Everything works great locally 🎉, but I’m running into trouble getting it to work in production. I believe the issue comes down to configuring Async::Job::Processor::Redis with the correct Redis instance.

I already have a REDIS_URL environment variable set, and my initializer looks like this:

# config/initializers/async_job_adapter.rb
require 'async/job/processor/redis'

Rails.application.configure do
  config.async_job.define_queue "default" do
    dequeue Async::Job::Processor::Redis
  end
end

In production, I get this error:

Errno::EADDRNOTAVAIL: Cannot assign requested address - connect(2) for [::1]:6379

It feels like the Redis client is not picking up my REDIS_URL and is defaulting to localhost.

I searched through the various Async gems for guidance, but couldn’t find anything on how to pass connection details (e.g. REDIS_URL).

I’d love some pointers on how to properly configure this. Once I get it working, I’d be more than happy to open a PR to improve the Async documentation around Redis setup.

Thanks again for all the work you’re doing! 🙏
