netplan-dbus - daemon to access Netplan functionality via a D-Bus API

netplan-dbus

netplan-dbus is a D-Bus daemon, providing io.netplan.Netplan on the system bus. The /io/netplan/Netplan object provides an io.netplan.Netplan interface, offering the following methods:

•
Apply() -> b: calls netplan apply and returns a success or failure status.
•
Generate() -> b: calls netplan generate and returns a success or failure status.
•
Info() -> a(sv): returns a dictionary "Features -> as", containing an array of all available feature flags.
•
Config() -> o: prepares a new configuration object as /io/netplan/Netplan/config/<ID>, by copying the current state from /{etc,run,lib}/netplan/*.yaml.

The /io/netplan/Netplan/config/<ID> objects provide a io.netplan.Netplan.Config interface, offering the following methods:

•
Get() -> s: calls netplan get --root-dir=/run/netplan/config-ID all and returns the merged YAML configuration of the the given configuration object's state
•
Set(s:CONFIG_DELTA, s:ORIGIN_HINT) -> b: calls netplan set --root-dir=/run/netplan/config-ID --origin-hint=ORIGIN_HINT CONFIG_DELTA

CONFIG_DELTA can be something like: network.ethernets.eth0.dhcp4=true and ORIGIN_HINT can be something like: 70-snapd (it will then write the configuration to 70-snapd.yaml). Once Set() is called on a configuration object, all other current and future configuration objects are being invalidated and cannot Set() or Try()/Apply() anymore, due to this pending dirty state. After the dirty configuration object is rejected via Cancel(), the other configuration objects are valid again. If the dirty configuration object is accepted via Apply(), newly created configuration objects will be valid, while the older states will stay invalid.

•
Try(u:TIMEOUT_SEC) -> b: replaces the main Netplan configuration with this configuration object's state and calls netplan try --timeout=TIMEOUT_SEC.
•
Cancel() -> b: rejects a currently running Try() attempt on this configuration object and/or discards the configuration object.
•
Apply() -> b: replaces the main Netplan configuration with this configuration object's state and calls netplan apply.

For information about the Apply()/Try()/Get()/Set() functionality, see netplan-apply(8)/netplan-try(8)/netplan-get(8)/netplan-set(8) accordingly. For details of the configuration file format, see netplan(5).
