salt.states.service¶

Starting or restarting of services and daemons¶

Services are defined as system daemons and are typically launched using system init or rc scripts. This service state uses whichever service module is loaded on the minion with the virtualname of service. Services can be defined as either running or dead.

If you need to know if your init system is supported, see the list of supported service modules for your desired init system (systemd, sysvinit, launchctl, etc.).

Note that Salt's service execution module, and therefore this service state, uses OS grains to ascertain which service module should be loaded and used to execute service functions. As existing distributions change init systems or new distributions are created, OS detection can sometimes be incomplete. If your service states are running into trouble with init system detection, please see the Overriding Virtual Module Providers section of Salt's module documentation to work around possible errors.

For services managed by systemd, the systemd_service module includes a built-in feature to reload the daemon when unit files are changed or extended. This feature is used automatically by the service state and the systemd_service module when running on a systemd minion, so there is no need to set up your own methods of reloading the daemon. If you need to manually reload the daemon for some reason, you can use the systemd_service.systemctl_reload function provided by Salt.

Note

The current status of a service is determined by the return code of the init/rc script status command. A status return code of 0 it is considered running. Any other return code is considered dead.

httpd:
  service.running: []

The service can also be set to start at runtime via the enable option:

openvpn:
  service.running:
    - enable: True

By default if a service is triggered to refresh due to a watch statement the service is restarted. If the desired behavior is to reload the service, then set the reload value to True:

redis:
  service.running:
    - enable: True
    - reload: True
    - watch:
      - pkg: redis

Note

More details regarding watch can be found in the Requisites documentation.

salt.states.service.dead(name, enable=None, sig=None, init_delay=None, **kwargs)¶

Ensure that the named service is dead by stopping the service if it is running

name

The name of the init or rc script used to manage the service

enable

Set the service to be enabled at boot time, True sets the service to be enabled, False sets the named service to be disabled. The default is None, which does not enable or disable anything.

sig

The string to search for when looking for the service process with ps

init_delay

Add a sleep command (in seconds) before the check to make sure service is killed.

New in version 2017.7.0.

no_blockFalse

For systemd minions only. Stops the service using --no-block.

New in version 2017.7.0.

timeout

For Windows minions only.

The time in seconds to wait for the service to stop before returning. Default is the default for win_service.stop.

New in version 2017.7.9,2018.3.4.

salt.states.service.disabled(name, **kwargs)¶

Ensure that the service is disabled on boot, only use this state if you don't want to manage the running process, remember that if you want to disable a service to use the enable: False option for the running or dead function.

name: The name of the init or rc script used to manage the service

salt.states.service.enabled(name, **kwargs)¶

Ensure that the service is enabled on boot, only use this state if you don't want to manage the running process, remember that if you want to enable a running service to use the enable: True option for the running or dead function.

name: The name of the init or rc script used to manage the service

salt.states.service.masked(name, runtime=False)¶

New in version 2017.7.0.

Note

This state is only available on minions which use systemd.

Ensures that the named service is masked (i.e. prevented from being started).

name: Name of the service to mask
runtimeFalse: By default, this state will manage an indefinite mask for the named service. Set this argument to True to runtime mask the service.

Note

It is possible for a service to have both indefinite and runtime masks set for it. Therefore, this state will manage a runtime or indefinite mask independently of each other. This means that if the service is already indefinitely masked, running this state with runtime set to True will _not_ remove the indefinite mask before setting a runtime mask. In these cases, if it is desirable to ensure that the service is runtime masked and not indefinitely masked, pair this state with a service.unmasked state, like so:

mask_runtime_foo:
  service.masked:
    - name: foo
    - runtime: True

unmask_indefinite_foo:
  service.unmasked:
    - name: foo
    - runtime: False

salt.states.service.mod_beacon(name, **kwargs)¶: Create a beacon to monitor a service based on a beacon state argument.

Note

This state exists to support special handling of the beacon state argument for supported state functions. It should not be called directly.

salt.states.service.mod_watch(name, sfun=None, sig=None, reload=False, full_restart=False, init_delay=None, force=False, **kwargs)¶

The service watcher, called to invoke the watch command. When called, it will restart or reload the named service.

Note

This state exists to support special handling of the watch requisite. It should not be called directly.

Parameters for this function should be set by the watching service (e.g. service.running).

name: The name of the service to control.
sfun: The original function which triggered the mod_watch call (service.running, for example).
sig: The string to search for when looking for the service process with ps.
reload: When set, reload the service instead of restarting it (e.g. service nginx reload).
full_restart: Perform a full stop/start of a service by passing --full-restart. This option is ignored if reload is set and is supported by only a few service modules.
force: Use service.force_reload instead of reload (needs reload to be set to True).
init_delay: Add a sleep command (in seconds) before the service is restarted/reloaded.

salt.states.service.running(name, enable=None, sig=None, init_delay=None, **kwargs)¶

Ensure that the service is running

name

The name of the init or rc script used to manage the service

enable

Set the service to be enabled at boot time, True sets the service to be enabled, False sets the named service to be disabled. The default is None, which does not enable or disable anything.

sig

The string to search for when looking for the service process with ps

init_delay

Some services may not be truly available for a short period after their startup script indicates to the system that they are. Provide an 'init_delay' to specify that this state should wait an additional given number of seconds after a service has started before returning. Useful for requisite states wherein a dependent state might assume a service has started but is not yet fully initialized.

no_blockFalse

For systemd minions only. Starts the service using --no-block.

New in version 2017.7.0.

timeout

For Windows minions only.

The time in seconds to wait for the service to start before returning. Default is the default for win_service.start.

New in version 2017.7.9,2018.3.4.

unmaskFalse

For systemd minions only. Set to True to remove an indefinite mask before attempting to start the service.

New in version 2017.7.0: In previous releases, Salt would simply unmask a service before making any changes. This behavior is no longer the default.

unmask_runtimeFalse

For systemd minions only. Set to True to remove a runtime mask before attempting to start the service.

New in version 2017.7.0: In previous releases, Salt would simply unmask a service before making any changes. This behavior is no longer the default.

wait3

For systemd minions only. Passed through when using service.status to determine whether the service is running or not.

New in version 2019.2.3.

Note

watch can be used with service.running to restart a service when: another state changes ( example: a file.managed state that creates the service's config file ). More details regarding watch can be found in the Requisites documentation.

salt.states.service.unmasked(name, runtime=False)¶

New in version 2017.7.0.

Note

This state is only available on minions which use systemd.

Ensures that the named service is unmasked

name: Name of the service to unmask
runtimeFalse: By default, this state will manage an indefinite mask for the named service. Set this argument to True to ensure that the service is runtime masked.
