We have a large deployment of around a dozen servers. We'd like to use the Whenever gem but I can't figure out a way to say which machine the cron jobs should go on! We only want these jobs to run on our server that does background jobs.

Is there a way to specify this?

If you deploy the project with Capistrano and you use the default Whenever recipe, you can create a new Capistrano role

role :whenever, "192.168.1.1"

and set the role in your deploy.rb file

set :whenever_roles, "whenever"

In this way, the task will be executed only on the specified server.

  • Works perfectly, thanks! Didn't know whenever had that option, helps to look at the capistrano file though obviously. – Nick Hammond Aug 10 '12 at 22:56

whenever is preconfigured to run against the db role, so if your db role is also the background machine's role you don't have to do the 'role :whenever, "192.168.0.1"' hack. see the codes
