NTP

Installs NTP on Linux.

Requirements

None.

Role Variables

Available variables are listed below, along with default values (see defaults/main.yml):

ntp_enabled: true

Whether to start the ntpd service and enable it at system boot. On many virtual machines that run inside a container (like OpenVZ or VirtualBox), it's recommended you don't run the NTP daemon, since the host itself should be set to synchronize time for all it's child VMs.

ntp_timezone: Etc/UTC

Set the timezone for your server.

ntp_manage_config: false

Set to true to allow this role to manage the NTP configuration file (/etc/ntp.conf).

ntp_area: ''

Set the NTP Pool Area to use. Defaults to none, which uses the worldwide pool.

ntp_servers:
  - "0{{ ntp_area }}.pool.ntp.org iburst"
  - "1{{ ntp_area }}.pool.ntp.org iburst"
  - "2{{ ntp_area }}.pool.ntp.org iburst"
  - "3{{ ntp_area }}.pool.ntp.org iburst"

Specify the NTP servers you'd like to use. Only takes effect if you allow this role to manage NTP's configuration, by setting ntp_manage_config to true.

ntp_restrict:
  - "127.0.0.1"
  - "::1"

Restrict NTP access to these hosts; loopback only, by default.

Dependencies

None.
