Usage

The Network Time Protocol (NTP) formula is used to properly synchronize services across the nodes. This file provides the sample configurations for different use cases.

  • [Deprecated] NTP client configuration, should not be used if the stratum parameter exists:

    ntp:
  client:
    enabled: true
    strata:
    - ntp.cesnet.cz
    - ntp.nic.cz

  • The NTP client extended definition with auth:

    ntp:
  client:
    enabled: true
    stratum:
      primary:
        server: ntp.cesnet.cz
        key_id: 1
      secondary:
        server: ntp.nic.cz
        key_id: 2

  • The NTP client with MD5 auth configuration:

    ntp:
  client:
    enabled: true
    auth:
      enabled: true
      secrets:
        1:
          secret_type: 'M'
          secret: 'Runrabbitrundigthath'
          trustedkey: true
        2:
          secret_type: 'M'
          secret: 'Howiwishyouwereherew'
          trustedkey: true
    stratum:
      primary:
        server: ntp.cesnet.cz
        key_id: 1
      secondary:
        server: ntp.nic.cz
        key_id: 2

  • The NTP server with MD5 auth configuration:

    ntp:
  client:
    enabled: false
  server:
    enabled: true
    auth:
      enabled: true
      secrets:
        1:
          secret_type: 'M'
          secret: 'Runrabbitrundigthath'
          trustedkey: true
        2:
          secret_type: 'M'
          secret: 'Howiwishyouwereherew'
          trustedkey: true
    stratum:
      primary:
        server: ntp.cesnet.cz
        key_id: 1
      secondary:
        server: ntp.nic.cz
        key_id: 2

  • A cleaning up of the NTP configurations left by DHCP:

    ntp:
  client:
    enabled: true
    remove_dhcp_conf: true # default false

  • The NTP server simple peering definition:

    ntp:
  server:
    peers:
    - 192.168.0.241
    - 192.168.0.242

  • The NTP server extended peering definition:

    ntp:
   server:
     peers:
       1:
         host: 192.168.31.1
       2:
         host: 192.168.31.2
       3:
         host: 192.168.31.3

  • The NTP server definition enabling the listen and ignore actions on specific addresses:

    ntp:
  server:
      1:
        value: wildcard
        action: ignore
      2:
        value: ::1
        action: listen
      3:
        value: 192.168.31.1
        action: listen

  • The NTP client orphan mode definition:

    ntp:
  client:
    enabled: true
    orphan: 5
    stratum:
      primary:
        server: ntp.cesnet.cz
