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.
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
The name of the init or rc script used to manage the service
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.
The string to search for when looking for the service process with ps
Add a sleep command (in seconds) before the check to make sure service is killed.

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

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.
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.
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 of the service to mask
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_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.
(i.e. service.running
)
The name of the init or rc script used to manage the service
The original function which triggered the mod_watch call (service.running, for example).
The string to search for when looking for the service process with ps
When set, reload the service instead of restarting it.
(i.e. service nginx reload
)
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
.
Use service.force_reload instead of reload (needs reload to be set to True)
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
The name of the init or rc script used to manage the service
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.
The string to search for when looking for the service process with ps
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.
For systemd minions only. Starts the service using --no-block
.
New in version 2017.7.0.
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.
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.
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 whenanother 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.

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 of the service to unmask
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.
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
indefinitely masked, running this state with runtime
set to
True
will _not_ remove the indefinite mask.
