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 on non-debian flavors is to write out /etc/sysctl.conf, which if you don't have settings in chef means you can kill your existing config. the sysctl_file atribute can control where this file goes in a role/override if you wish.
Attributes
- sysctl: Hash of k/v pairs with sysctl settings.
- sysctl_file: The location we write out the configuration defaults to /etc/sysctl.conf on anything not debian flavor defaults to /etc/sysctl.d/99-chef.conf on debian
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: false)
Actions
- :set Make sure the running state is set (default)
- :write Write the config file (default)
Known Bugs
- only intended to be used on Linux
Example Usage
