How to setup maintenance tasks with a custom controller?

Hi!

I want to try out maintenance tasks, but before I proceed, I need to know how to overwrite the controller provided by the engine. I'd like to add authorization to only allow admins to access the maintenance page.

One thing that can be done is to wrap the route in a constraint, like it's usually done with Sidekiq for example: https://github.com/mperham/sidekiq/wiki/Monitoring#authentication

You can also directly access MaintenanceTasks::ApplicationController and use a before_action there if you want, e.g.:

# config/initializers/maintenance_tasks.rb
Rails.application.config.to_prepare do
  MaintenanceTasks::ApplicationController.class_eval do
    include Authentication
    before_action :authenticate
  end
end

I tested with a custom constraint class, and it works really well! Thanks for the help 🧡
