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
