Netplan v0.107 is now available

by

I’m happy to announce that Netplan version 0.107 is now available on GitHub and is soon to be deployed into a Linux installation near you! Six months and more than 200 commits after the previous version (including a .1 stable release), this release is brought to you by 8 free software contributors from around the globe.

Highlights

Highlights of this release include the new configuration types for veth and dummy interfaces:

network:
  version: 2
  virtual-ethernets:
    veth0:
      peer: veth1
    veth1:
      peer: veth0
  dummy-devices:
    dm0:
      addresses:
        - 192.168.0.123/24
      ...

Furthermore, we implemented CFFI based Python bindings on top of libnetplan’s API, that can easily be consumed by 3rd party applications (see full cffi-bindings.py example):

from netplan import Parser, State, NetDefinition
from netplan import NetplanException, NetplanParserException

parser = Parser()

# Parse the full, existing YAML config hierarchy
parser.load_yaml_hierarchy(rootdir='/')

# Validate the final parser state
state = State()
try:
    # validation of current state + new settings
    state.import_parser_results(parser)
except NetplanParserException as e:
    print('Error in', e.filename, 'Row/Col', e.line, e.column, '->', e.message)
except NetplanException as e:
    print('Error:', e.message)

# Walk through ethernet NetdefIDs in the state and print their backend
# renderer, to demonstrate working with NetDefinitionIterator &
# NetDefinition
for netdef in state.ethernets.values():
    print('Netdef', netdef.id, 'is managed by:', netdef.backend)
    print('Is it configured to use DHCP?', netdef.dhcp4 or netdef.dhcp6)
