Rack::Maintenance is a simple Rack middleware to detect the existence of a maintenance page and display that instead of incoming requests.
sudo gem install rack-maintenance
Installation with Bundler
and then run `bundle`.
# html maintenance response config.middleware.use 'Rack::Maintenance', :file => Rails.root.join('public', 'maintenance.html'), :env => 'MAINTENANCE' # json maintenance response # it's up to you to provide a valid JSON file! config.middleware.use 'Rack::Maintenance', :file => Rails.root.join('public', 'maintenance.json'), :env => 'MAINTENANCE'
If :env is specified, all requests will be shown the maintenance page if the environment variable is set.
If :env is not specified, the maintenance page will be shown if it exists.
# Leave some paths enabled while site is down # You'll usually want to exclude /assets if you'd like to retain CSS. # It also works for allowing access to admin while the rest is in maintenance mode. config.middleware.use 'Rack::Maintenance', :file => Rails.root.join('public', 'maintenance.html'), :without => /\A\/assets/
