This article summarizes how saltstack locates the target host and introduces some common examples. > Why do I need to locate the host? As a configuration management software, the first thing to solve is how to determine the push host, or the push target of a specific configuration.

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 (GITF
