lockrun-cookbook
Installs the lockrun executable for running cronjobs with overrun protection.
Basic Usage
This cookbook is extremely useful when you only want to have a single process running at a time. We use this to ensure that there is only ever one Chef Client running at a time. If a process already has the lock it bails out immediately.
Instead of writing a wrapper script every time you want this functionality simply use the lockrun executable. It counts the number of open file descriptors to a lockfile on disk. ```ruby include_recipe 'lockrun::default'
sleep_time = 0 unless node['chef_client']['splay'].to_i == 0 checksum = Digest::MD5.hexdigest(node['fqdn'] || 'unknown-hostname') sleep_time = checksum.to_s.hex % node['chef_client']['splay'].to_i end
lockrun_cron 'chef-client' do command "/bin/sleep #{sleep_time}; chef-client > /dev/null 2>&1" cron_options(minute: '0', hour: '', weekday: '') end ```
Out of the box the following platforms are certified to work and are tested using our [Test Kitchen][8] configuration. Additional platforms may work, but your mileage may vary. - CentOS (RHEL) 5.8, 6.6, 7.1 - Ubuntu 12.04, 14.04
