Chrony time service deployment using ansible, this YAML file
creates the interface between the HOT template
and the ansible role that actually installs
and configure chronyd.
parameters:
ServiceData:
default: {}
description: Dictionary packing service data
type: json
ServiceNetMap:
default: {}
description: Mapping of service_name -> network name. Typically set
via parameter_defaults in the resource registry. This
mapping overrides those in ServiceNetMapDefaults.

DefaultPasswords:
default: {}
type: json
RoleName:
default: ''
description: Role name on which the service is applied
type: string
RoleParameters:
default: {}
description: Parameters specific to the role
type: json
EndpointMap:
default: {}
description: Mapping of service endpoint -> protocol. Typically set
via parameter_defaults in the resource registry.
type: json
NtpServer:
default: ['0.pool.ntp.org', '1.pool.ntp.org', '2.pool.ntp.org', '3.pool.ntp.org']
description: NTP servers list. Defaulted to a set of pool.ntp.org servers
in order to have a sane default for Pacemaker deployments when
not configuring this parameter by default.
type: comma_delimited_list
NtpPool:
default: []
description: NTP pool list. Defaults to [], so only NtpServer is used by
default.
type: comma_delimited_list
ChronyGlobalServerOptions:
default: ''
description: Default server options for the configured NTP servers in
chrony.conf. If this is specified, NtpIburstEnable, MaxPoll,
and MinPoll are ignored.
type: string
ChronyGlobalPoolOptions:
default: ''
description: Default pool options for the configured NTP pools in
chrony.conf. If this is specified, NtpIburstEnable, MaxPoll,
and MinPoll are ignored.
type: string
NtpIburstEnable:
default: true
description: Specifies whether to enable the iburst option for every NTP
peer. If iburst is enabled, when the ntp server is unreachable
ntp will send a burst of eight packages instead of one. This
is designed to speed up the initial syncrhonization.
type: boolean

description: Specify maximum poll interval of upstream servers for NTP
messages, in seconds to the power of two.
The maximum poll interval defaults to 10 (1,024 s).
Allowed values are 4 to 17.

default: 10
constraints:
- range: { min: 4, max: 17 }
MinPoll:
description: Specify minimum poll interval of upstream servers for NTP
messages, in seconds to the power of two.
The minimum poll interval defaults to 6 (64 s).
