class maasserver.models.nodegroup.NodeGroup(*args, **kwargs)

Bases: maasserver.models.timestampedmodel.TimestampedModel

NodeGroup(id, created, updated, cluster_name, name, status, api_token_id, api_key, dhcp_key, uuid, maas_url)

accept()

Accept this nodegroup’s enlistment.

reject()

Reject this nodegroup’s enlistment.

get_managed_interfaces()

Return the list of interfaces for which MAAS manages DHCP.

ensure_boot_source_definition()

Set default boot source if none is currently defined.

manages_dns()

Does this NodeGroup manage DNS on any interfaces?

This returns True when the NodeGroup is accepted, and has a NodeGroupInterface that’s set to manage both DHCP and DNS.

ensure_dhcp_key()

Ensure that this nodegroup has a dhcp key.

This method persists the dhcp key without triggering the model signals (pre_save/post_save/etc) because it’s called from dhcp.configure_dhcp which, in turn, it called from the post_save signal of NodeGroup.

work_queue

The name of the queue for tasks specific to this nodegroup.

The files are downloaded through the proxy defined in the config setting ‘http_proxy’ if defined.

Parameters:

• poweraddr – virsh connection string
• password – ssh password
