# Capistrano Recipes for managing delayed_job
#
# Add these callbacks to have the delayed_job process restart when the server
# is restarted:
#
# after "deploy:stop", "delayed_job:stop"
# after "deploy:start", "delayed_job:start"
# after "deploy:restart", "delayed_job:restart"
#
# If you want to use command line options, for example to start multiple workers,
# define a Capistrano variable delayed_job_args:
#
# set :delayed_job_args, "-n 2"
#
# If you've got delayed_job workers running on a servers, you can also specify
# which servers have delayed_job running and should be restarted after deploy.
#
# set :delayed_job_server_role, :worker
#
Capistrano::Configuration.instance.load do
namespace :delayed_job do
def rails_env
fetch(:rails_env, false) ? "RAILS_ENV=#{fetch(:rails_env)}" : ''
end
def args
fetch(:delayed_job_args, '')
end
def roles
fetch(:delayed_job_server_role, :app)
end
def delayed_job_command
fetch(:delayed_job_command, 'script/delayed_job')
end
desc 'Stop the delayed_job process'
task :stop, :roles => lambda { roles } do
run "cd #{current_path} && #{rails_env} #{delayed_job_command} stop #{args}"
end
desc 'Start the delayed_job process'
task :start, :roles => lambda { roles } do
run "cd #{current_path} && #{rails_env} #{delayed_job_command} start #{args}"
end
desc 'Restart the delayed_job process'
task :restart, :roles => lambda { roles } do
run "cd #{current_path} && #{rails_env} #{delayed_job_command} restart #{args}"
end
end
