The combination of Saltstack and Python programs

Modules in the Saltstack library:

in Saltstack, each subsystem plug-in (plug-in) is a Python Module. Therefore, the Module in the Saltstack library can be seen as a set of functions (for example: aka command); it can be seen as an application (e.g. MySQL, Docker); can be seen as a system component (e.g. disk, file) ; it can also be seen as an external system (GITFS). There are a few things to keep in mind when using Modules in the Saltstack Library: (1). All modules are in the Salt directory, each subsystem is differentiated by a different subdirectory, and each specific modile will be presented in a separate. py file, (2). Each module isSalt . Subsystem.module The format named, where SubsystemRepresents a subsystem, ModuleRepresents the Subsystem module name. Note:Because the Execute (execution) module is the first module in the Salt, itSalt.module(3). Each module contains the functions we need. Functions in the Saltstack library:in Saltstack, Functions is the equivalent of a verb.   Functions parameter (Arguments) in the Saltstack library: 1. Specify the Functions parameter in the command line modeIn general, the required shape arguments in Functions are first specified and arranged in a particular order. Rather than the required formal parameter all with default values。 When calling Function in a Salt named row mode, if the parameter does not have aArgument=valueis specified in the form of a value only, we need to separate the parameters with a space and specify them in a specific order. If theArgument=valueThe form is irrelevant. For example: Define the following function>>>Salt.modules.useradd.add (name, Uid=none, Gid=none, Groups=none, Home=none,Shell=none, Unique=true, System=false, fullname= ", oomnumber=",workphone= ", homephone=", Createhome=true, Loginclass=none)The following is called in command-line mode. >>>Salt ' * ' User.add Fred Shell=/bin/zsh Note:When you use the deformable parameter ( Variable nameless parameter *args and variable keyword parameters **kw), the variable-name parameter is directly filled in as a value, and the variable-keyword argument isArgument=valuespecified in the form. For example: 1 variable nameless parameters and 3 variable key glyph parameters are specified. >>>Salt ' * ' network.connect google-public-dns-a.google.com port=53 proto=udp timeout=3 2. Formal parameter designation for State systemThe formal parameters of the state system are stored in the state file, based on YAML's syntax. For example, salt.states.user.present is defined as follows. >>>salt.states.user.present (name, Uid=none, Gid=none, Gid_from_name=false,Groups=none, Optional_groups=none, Remove_groups=true, Home=none,createhome=true, Password=none, Hash_password=false, Enforce_password=true,Empty_password=false, Shell=none, Unique=true, System=false, Fullname=none,Roomnumber=none, Workphone=none, Homephone=none, Loginclass=none, Date=none,Mindays=none, Maxdays=none, Inactdays=none, Warndays=none, Expire=none,Win_homedrive=none, Win_profile=none, Win_logonscript=none,Win_description=none)In the state file, the YAML syntax is specified similar to the following.A state example that calls User.present:user.present:-name:fred-Shell:/bin/zsh Reference Connection:Https://docs.saltstack.com/en/getstarted/system/python.html
