• package - removes competing packages and installs chrony.

Usage

If you are fine with using the public NTP servers you can simply include chrony_ii in your node's run_list:

{
  "name":"my_node",
  "run_list": [
    "recipe[chrony_ii]"
  ]
}

If you need to control your configuration use a role.
