octavia.compute.drivers.nova_driver module

class VirtualMachineManager

Bases: ComputeBase

Compute implementation of virtual machines via nova.

attach_network_or_port(compute_id, network_id=None, ip_address=None, port_id=None)

Attaching a port or a network to an existing amphora

Parameters:

• compute_id – id of an amphora in the compute service

• network_id – id of a network

• ip_address – ip address to attempt to be assigned to interface

• port_id – id of the neutron port

Returns:

nova interface instance

Raises:

• ComputePortInUseException – The port is in use somewhere else

• ComputeUnknownException – Unknown nova error

build(name='amphora_name', amphora_flavor=None, image_tag=None, image_owner=None, key_name=None, sec_groups=None, network_ids=None, port_ids=None, config_drive_files=None, user_data=None, server_group_id=None, availability_zone=None)

Create a new virtual machine.

Parameters:

• name – optional name for amphora

• amphora_flavor – image flavor for virtual machine

• image_tag – image tag for virtual machine

• key_name – keypair to add to the virtual machine

• sec_groups – Security group IDs for virtual machine

• network_ids – Network IDs to include on virtual machine

• port_ids – Port IDs to include on virtual machine

• config_drive_files – An optional dict of files to overwrite on the server upon boot. Keys are file names (i.e. /etc/passwd) and values are the file contents (either as a string or as a file-like object). A maximum of five entries is allowed, and each file must be 10k or less.

• user_data – Optional user data to pass to be exposed by the metadata server this can be a file type object as well or a string

• server_group_id – Optional server group id(uuid) which is used for anti_affinity feature

• availability_zone – Name of the compute availability zone.

Raises:

ComputeBuildException – if nova failed to build virtual machine

Returns:

UUID of amphora

create_server_group(name, policy)

Create a server group object

Parameters:

• name – the name of the server group

• policy – the policy of the server group

Raises:

Generic exception if the server group is not created

Returns:

the server group object

delete(compute_id)

Delete a virtual machine.

Parameters:

compute_id – virtual machine UUID

delete_server_group(server_group_id)

Delete a server group object

Raises:

Generic exception if the server group is not deleted

Parameters:

server_group_id – the uuid of a server group

detach_port(compute_id, port_id)

Detaches a port from an existing amphora.

Parameters:

• compute_id – id of an amphora in the compute service

• port_id – id of the port

Returns:

None

get_amphora(compute_id, management_network_id=None)

Retrieve the information in nova of a virtual machine.

Parameters:

• compute_id – virtual machine UUID

• management_network_id – ID of the management network

Returns:

an amphora object

Returns:

fault message or None

status(compute_id)

Retrieve the status of a virtual machine.

Parameters:

compute_id – virtual machine UUID

Returns:

constant of amphora status

validate_availability_zone(availability_zone)

Validates that an availability zone exists in nova.

Parameters:

availability_zone – Name of the availability zone to lookup.

Raises:

NotFound

Returns:

None

validate_flavor(flavor_id)

Validates that a flavor exists in nova.

Parameters:

flavor_id – ID of the flavor to lookup in nova.

Raises:

NotFound

Returns:

None
