chrony

This tool installs and configures chrony on RHEL/CentOS or Debian/Ubuntu servers.

Requirements

To use this tool, you need root access. Make sure to include become: yes at the top of your playbook. You can also call the role in your playbook like this:

- hosts: chrony
  roles:
    - role: engonzal.chrony
      become: yes

Role Variables

Here are some available variables with examples:

chrony_servers:
  - time.cloudflare.com iburst prefer port 1514
chrony_pools:
  - ntp.ubuntu.com        iburst maxsources 2

You can customize the servers and pools. By default, it uses the Ubuntu and Cloudflare pools.

chrony_measurements_statistics_tracking: false
chrony_disable_external_client: true

You can also enable extra logging and let your chrony daemon accept incoming NTP connections (it’s safer to disable this).
