Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Installs the lockrun executable for running cronjobs with overrun

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.
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

lockrun_cron 'chef-client' do
command "/bin/sleep #{sleep_time}; chef-client > /dev/null 2>&1"
cron_options(minute: '0', hour: '', weekday: '')

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
