Add Authentication Behind Your Sidekiq Dashboard (or any route)

If you need to add authentication behind your Sidekiq dashboard, then you can add the following to your routes.rb file.

  scope :monitoring do
    Sidekiq::Web.use Rack::Auth::Basic do |username, password|
      ActiveSupport::SecurityUtils.secure_compare(::Digest::SHA256.hexdigest(username), ::Digest::SHA256.hexdigest(ENV["ADMIN_USERNAME"])) &
        ActiveSupport::SecurityUtils.secure_compare(::Digest::SHA256.hexdigest(password), ::Digest::SHA256.hexdigest(ENV["ADMIN_PASSWORD"]))
    end

    mount Sidekiq::Web, at: '/sidekiq'
  end

You can set the required username and password by updating the environment variables ADMIN_USERNAME and ADMIN_PASSWORD.

Then, whenever you visit localhost:3000/monitoring/sidekiq, you'll be able to see a nice dashboard with details about your background jobs. Woah, beautiful!

If you're using something like Devise, then it's even easier. Add the following to your routes.rb.

authenticate :user, lambda { |u| u.has_role? :site_admin } do
    mount Sidekiq::Web => '/sidekiq'
    get 'user_list' => 'pages#user_list'
  end

As you can see above, it's straightforward to add any route behind the authentication.

Hope this pattern helps. Happy coding.
