If False, only the primary nic will be configured and only with dhcp (IPv4/IPv6). @return A dict of network config version 2 based on the metadata and macs. r� )�version� ethernetsr[ r\ TFZ macaddress)�dhcp4�dhcp6�match�set-namer r r r z route-metricr� �d )r �dhcp4-overridesr r r r� z use-routes)r6 r r r r zdhcp6-overrides� addressesr Nr r )r Zget_interfaces_by_macr] ra rW r� Znetwork_rendererr ZRendererr� r� r� r �get_secondary_addresses�popr� )Z network_mdr6 r� r� r� r� Znetcfgr� r� r r r Z is_netplanr� r\ Znic_idxZis_primary_nicZ dhcp_overrider r" r" r# r� � s� � � ����� ���� r� c C s� | � d�}| � d�}g }tt|t�o.t|�dk�rH|�t| d||d�� tt|t�o^t|�dk�rx|�t| d||d�� t|�S )z�Parse interface-specific nic metadata and return any secondary IPs :return: List of secondary IPv4 or IPv6 addresses to configure on the interface r r r� r Z24zsubnet-ipv6-cidr-blockZ128)rW r� r� r� r� �extend�_get_secondary_addressesr� )r r� Zipv4sr r r" r" r# r s s �� ��r c C s� g }| � |�}|}|r(t|�d��dkrNd|v r4dnd}t�d|||||� n|�d�d }|dd� D ]} |�dj| |d �� qh|S ) z�Return list of IP addresses as CIDRs for secondary IPs The CIDR prefix will be default_prefix if cidr_key is absent or not parseable in nic_metadata. r� r� rC rD zJCould not parse %s %s for mac %s. %s network config prefix defaults to /%sr� Nz {ip}/{prefix})r �prefix)rW r� �splitrP r� r� rk ) r Zcidr_keyr� r �default_prefixr Zcidrr Zip_typer r" r" r# r � s" � r c C s t �| t�S r- )r Zlist_from_depends� datasources)Zdependsr" r" r# �get_datasource_list� s r" )Fr� Zloggingr� r� r� � contextlibr �typingr r Z cloudinitr r r r rl r r Zcloudinit.distrosr Zcloudinit.eventr r Z cloudinit.netr Zcloudinit.net.dhcpr Zcloudinit.net.ephemeralr Zcloudinit.sourcesr Zcloudinit.sources.helpersr Z getLoggerr rP rN rO r r( r r� r= Z DataSourcer) r� rL r� r� r� r� r� r� r� r? r� r2 r� r� r� r� r� r r� r r ZDEP_FILESYSTEMZ DEP_NETWORKr! r" r" r" r" r# �<module> s� w! #� � D� X� | �
