Nmstate provides a set of libraries with an accompanying command line tool that manages host networking settings in a declarative manner. The networking state is described by a pre-defined schema. Reporting of current state and changes to it (desired state) both conform to the schema.
Nmstate is aimed to satisfy enterprise needs to manage host networking through a northbound declarative API and multi provider support on the southbound. 网络Manager acts as the main provider supported.
