Rails: How to setup Heroku with Redis and Sidekiq
<p>I'm trying to get Sidekiq to work with the <a href="https://elements.heroku.com/addons/heroku-redis" rel="nofollow">Heroku Redis</a>.</p>

<p>I have <code>Heroku Redis</code> as an addon on my app and and have added</p>

<pre><code>worker: bundle exec sidekiq -C ./config/sidekiq.yml
</code></pre>

<p>to my <code>procfile</code> but when I start the worker I see this error in my logs:</p>

<pre><code>No such file or directory - /app/tmp/pids/sidekiq.pid 
</code></pre>

<p>How can I go about getting Sidekiq to run with Heroku Redis?</p>
