crontabinator

Repeatably install crontabs

This is a Capistrano 3.x plugin, and relies on SSH access with passwordless sudo rights.

• gem install crontabinator (Or add it to your Gemfile and bundle install.)
• Add "require 'crontabinator'" to your Capfile echo "require 'crontabinator'" >> Capfile
• Create example configs: cap crontabinator:write_example_configs
• Turn them into real configs by removing the _example portions of their names, and adjusting their content to fit your needs. (Later when you upgrade to a newer version of crontabinator, you can crontabinator:write_example_configs again and diff your current configs against the new configs to see what you need to add.)
• Add the role :cron to whatever servers you would like to have crons installed upon.
• Ensure the scripts.d/ directory's files have 1 and only 1 line above your shebang line, in the form { :user => "root", :schedule => '* * * * *', :stages => [:production] }
• Ensure the scripts.d/ directory's files get set executable (E.G. using deployinator's :webserver_executeable_dirs)

cap -T will help remind you of the available commands, see this for more details.

• After setting up your config files during installation, simply run: cap <stage> crontab:setup
• Run cap <stage> crontab:status to see the status of the crontabs.

• You can add the --trace option at the end of a command to see when which tasks are invoked, and when which task is actually executed.
