YAML configuration#

Netplan’s configuration files use the YAML format. All /{lib,etc,run}/netplan/*.yaml are considered.

The top-level node in a netplan configuration file is a network: mapping that contains version: 2 (the YAML currently being used by curtin, MaaS, etc. is version 1), and then device definitions grouped by their type, such as ethernets:, modems:, wifis:, or bridges:. These are the types that our renderer can understand and are supported by our backends.

API specification#

libnetplan is a component of the Netplan. project that contains the logic for data parsing, validation and generation. It is build as a dynamic .so library that can be used from different binaries (like Netplan’s generate, netplan-dbus, the netplan apply/try/get/set/... CLI or via the corresponding Python bindings or external applications like the NetworkManager, using the Netplan backend).

Netplan CLI#

Netplan’s manpages describe the usage of the different command line interface tools available. Those are also installed on a system running Netplan and can be accessed, using the man utility.

Netplan D-Bus#

Netplan provides a daemon that can be run to provide the io.netplan.Netplan D-Bus API, to control certain aspects of a system’s Netplan configuration programmatically. See also: DBus config API.
