I’m having a problem getting Sidekiq up and running on my Heroku deployed Rails

  • 0

I’m having a problem getting Sidekiq up and running on my Heroku deployed Rails app. I have my app working fine in development (and on Heroku without Sidekiq).

I created a Procfile with:

worker: bundle exec sidekiq

If I run heroku ps, the only process I see is web.1.

Should I see one for
Sidekiq?

I do get an error:

Redis::CannotConnectError (Error connecting to Redis on localhost:6379) in my Heroku logs.

UPDATE: Found I probably needed heroku addons:add redistogo. Still not working. I feel I’m missing some basic configuration.

Is there something I need to do to get Redis up and running for my Heroku app?

I’ve been using Redis/Sidekiq for about a day, so this is new to me.

Thanks!

Greg

    No you do not need any config with Heroku for Sidekiq, just add the RedisToGo plugin and you’re on.
    Do not forget to attribute at least 1 worker to your app in your Heroku config.

    Here is my default Procfile:

    web: bundle exec thin start -p $PORT
worker: bundle exec sidekiq -c 5 -v
