nosh – Manage services with nosh

New in version 2.5.

Synopsis

  • Control running and enabled state for system-wide or user services.
  • BSD and Linux systems are supported.

Requirements

The below requirements are needed on the host that executes this module.

  • A system with an active nosh service manager, see Notes for further information.

Parameters

Parameter Choices/Defaults Comments
enabled
boolean
    Choices:
  • no
  • yes
Enable or disable the service, independently of *.preset file preference or running state. Mutually exclusive with preset. Will take effect prior to state=reset.
name
- / required
Name of the service to manage.
preset
boolean
    Choices:
  • no
  • yes
Enable or disable the service according to local preferences in *.preset files. Mutually exclusive with enabled. Only has an effect if set to true. Will take effect prior to state=reset.
state
-
    Choices:
  • started
  • stopped
  • reset
  • restarted
  • reloaded
started/stopped are idempotent actions that will not run commands unless necessary. restarted will always bounce the service. reloaded will send a SIGHUP or start the service. reset will start or stop the service according to whether it is enabled or not.
user
boolean
    Choices:
  • no ←
  • yes
Run system-control talking to the calling user's service manager, rather than the system-wide service manager.

- name: for package installers, set nginx running state according to local enable settings, preset and reset

  tasks:
    - name: obtain information on tinydns service
      nosh: name=tinydns
