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
