short_description:  Manage services
description:
    - Controls services on remote hosts. Supported init systems include BSD init,
      OpenRC, SysV, Solaris SMF, systemd, upstart.
    - For Windows targets, use the M(win_service) module instead.

        - Name of the service.
        required: true
    state:
        description:
          - C(started)/C(stopped) are idempotent actions that will not run
            commands unless necessary.  C(restarted) will always bounce the
            service.  C(reloaded) will always reload. B(At least one of state
            and enabled are required.) Note that reloaded will start the
            service if it is not already started, even if your chosen init
            system wouldn't normally.
        choices: [ reloaded, restarted, started, stopped ]
    sleep:
        description:
        - If the service is being C(restarted) then sleep this many seconds
          between the stop and start command. This helps to workaround badly
          behaving init scripts that exit immediately after signaling a process
          to stop.
        version_added: "1.3"
    pattern:
        description:
        - If the service does not respond to the status command, name a
          substring to look for as would be found in the output of the I(ps)
          command as a stand-in for a status result.  If the string is found,
          the service will be assumed to be started.
        version_added: "0.7"
    enabled:
        description:
        - Whether the service should start on boot. B(At least one of state and
          enabled are required.)
        type: bool
    runlevel:
        description:
        - "For OpenRC init scripts (ex: Gentoo) only.  The runlevel that this service belongs to."
        default: default
    arguments:
        description:
        - Additional arguments provided on the command line
        aliases: [ args ]
    use:
        description:
            - The service module actually uses system specific modules, normally through auto detection, this setting can force a specific module.
            - Normally it uses the value of the 'ansible_service_mgr' fact and falls back to the old 'service' module when none matching is found.
        default: auto
        version_added: 2.2
notes:
    - For Windows targets, use the M(win_service) module instead.
