rack-maintenance¶ ↑

Rack::Maintenance is a simple Rack middleware to detect the existence of a maintenance page and display that instead of incoming requests.

Installation¶ ↑

sudo gem install rack-maintenance

Installation with Bundler¶ ↑

In Gemfile:

gem 'rack-maintenance'

and then run `bundle`.

Usage¶ ↑

# 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'

# You may provide an object that responds to call to provide
# post-processing of the maintenance page such as merging
# ENV values into the page through ERB
config.middleware.use 'Rack::Maintenance',
  :file => Rails.root.join('public', 'maintenance.html.erb'),
  :env  => 'MAINTENANCE',
  :processor => lambda { |content| ERB.new(content).result }

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/
