Offers deploy:web:disable and deploy:web:enable tasks for Capistrano.
branch: master

Capistrano Maintenance Extension

This gem simply offers the recently removed deploy:web:disable and deploy:web:enable tasks to your Capistrano deployment.


Install the gem via rubygems:

gem install capistrano-maintenance

And put this line into your deploy.rb file:

require 'capistrano/maintenance'

Now, you can disable the web:

cap deploy:web:disable

You can also specify a string to specify reason and how long it is until:

cap deploy:web:disable REASON="For server upgrades" UNTIL="3AM EST"

When maintenance is done, you can enable the web:

cap deploy:web:enable

If you are using multistage capistrano, you'll also need to include the stage before deploy:web:disable and deploy:web:enable:

cap production deploy:web:disable
cap production deploy:web:enable


Everything should work out of the box general, but there are some additional adjustments you can make in your deploy.rb.

# change the default filename from maintenance.html to disabled.html
set :maintenance_basename, 'disabled'

# change default directory from default of #{shared_path}/system
set :maintenance_dirname, "#{shared_path}/public/system"

# use local template instead of included one with capistrano-maintenance
set :maintenance_template_path, 'app/views/maintenance.html.erb'

# disable the warning on how to configure your server
set :maintenance_config_warning, false

For your custom maintenance template, you have access to the following variables, if they're defined:

  • reason
  • deadline

These are the environment variables passed in via REASON="something" and UNTIL="later"
