Nmstate: A Declarative Network API

A declarative network management API for hosts.

[ [

Copr build status, all repos are built for Fedora Linux and RHEL/CentOS Stream/EPEL 8+:

• Latest release:
• Git base:

Nmstate is a library 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. NetworkManager acts as the main (and currently the only) provider supported.

Nmstate provides:

• Rust crate -- nmstate
• Command line tools -- cargo install nmstatectl
• Python library -- libnmstate
• Go binding
• C binding
