DESCRIPTION

Manage sysctl sysctl provider.
Default recipe reads key value pairs from node attributes and ensures the system state.

NOTE: If you are getting this from the community site I've renamed it jn_sysctl, you will have to rename the cookbook to sysctl

WARNING: The default behavior is to write out /etc/sysctl.conf, which if you don't have settings in chef means you can kill your existing config.

Attributes

• sysctl: Hash of k/v pairs with sysctl settings.

Sysctl LWRP

Properties

• name: The key name. Defaults to the resource name i.e. sysctl "some.key"
• value: what to set this key to
• save: save the setting back to the node data (default: yes)

Actions

• :set Make sure the running state is set (default)
• :write Write the config file (default)

Known Bugs

• only really tested on CentOS/RedHat and Linux in general. YMMV on other platforms

Example Usage

LWRP

Ensure running state, and write this key to sysctl.conf

sysctl "kernel.sysrq" do
   value 1
end
