netapi modules¶

Introduction to netapi modules¶

netapi modules provide API-centric access to Salt. Usually externally-facing services such as REST or WebSockets, XMPP, XMLRPC, etc.

In general netapi modules bind to a port and start a service. They are purposefully open-ended. A single module can be configured to run as well as multiple modules simultaneously.

netapi modules are enabled by adding configuration to your Salt Master config file and then starting the salt-api daemon. Check the docs for each module to see external requirements and configuration settings.

Communication with Salt and Salt satellite projects is done using Salt's own Python API. A list of available client interfaces is below.

Client interfaces¶

Salt's client interfaces expose executing functions by crafting a dictionary of values that are mapped to function arguments. This allows calling functions simply by creating a data structure. (And this is exactly how much of Salt's own internals work!)

class salt.netapi.NetapiClient(opts)¶

Provide a uniform method of accessing the various client interfaces in Salt in the form of low-data data structures. For example:

>>> client = NetapiClient(__opts__)
>>> lowstate = {'client': 'local', 'tgt': '*', 'fun': 'test.ping', 'arg': ''}
>>> client.run(lowstate)

local(*args, **kwargs)¶

Run execution modules synchronously

See salt.client.LocalClient.cmd() for all available parameters.

Sends a command from the master to the targeted minions. This is the same interface that Salt's own CLI uses. Note the arg and kwarg parameters are sent down to the minion(s) and the given function, fun, is called with those parameters.

返回:	Returns the result from the execution module

local_async(*args, **kwargs)¶

Run execution modules asynchronously

Wraps salt.client.LocalClient.run_job().

返回:	job ID

local_batch(*args, **kwargs)¶

Run execution modules against batches of minions

Wraps salt.client.LocalClient.cmd_batch()

返回:	Returns the result from the exeuction module for each batch of returns

local_subset(*args, **kwargs)¶

Run execution modules against subsets of minions

2016.3.0 新版功能.

Wraps salt.client.LocalClient.cmd_subset()

runner(fun, timeout=None, **kwargs)¶

Run runner modules <all-salt.runners> synchronously

Wraps salt.runner.RunnerClient.cmd_sync().

Note that runner functions must be called using keyword arguments. Positional arguments are not supported.

返回:	Returns the result from the runner module

runner_async(fun, **kwargs)¶

Run runner modules <all-salt.runners> asynchronously

Wraps salt.runner.RunnerClient.cmd_async().

Note that runner functions must be called using keyword arguments. Positional arguments are not supported.

返回:	event data and a job ID for the executed function.

ssh(*args, **kwargs)¶

Run salt-ssh commands synchronously

Wraps salt.client.ssh.client.SSHClient.cmd_sync().

返回:	Returns the result from the salt-ssh command

ssh_async(fun, timeout=None, **kwargs)¶

Run salt-ssh commands asynchronously

Wraps salt.client.ssh.client.SSHClient.cmd_async().

返回:	Returns the JID to check for results on

wheel(fun, **kwargs)¶

Run wheel modules synchronously

Wraps salt.wheel.WheelClient.master_call().

Note that wheel functions must be called using keyword arguments. Positional arguments are not supported.

返回:	Returns the result from the wheel module

wheel_async(fun, **kwargs)¶

Run wheel modules asynchronously

Wraps salt.wheel.WheelClient.master_call().

Note that wheel functions must be called using keyword arguments. Positional arguments are not supported.

返回:	Returns the result from the wheel module
