class VirtualMachineManager[source]¶

Bases: octavia.compute.compute_base.ComputeBase

Compute implementation of virtual machines via nova.

attach_network_or_port(compute_id, network_id, ip_address=None, port_id=None)[source]¶

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:	Exception

build(name='amphora_name', amphora_flavor=None, image_id=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)[source]¶

Create a new virtual machine.

Parameters:	name – optional name for amphora amphora_flavor – image flavor for virtual machine image_id – image ID 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
Raises:	ComputeBuildException – if nova failed to build virtual machine
Returns:	UUID of amphora

create_server_group(name, policy)[source]¶

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)[source]¶

Delete a virtual machine.

Parameters:	compute_id – virtual machine UUID

delete_server_group(server_group_id)[source]¶

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)[source]¶

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)[source]¶

Retrieve the information in nova of a virtual machine.

Parameters:	amphora_id – virtual machine UUID
Returns:	an amphora object
Returns:	fault message or None

status(compute_id)[source]¶

Retrieve the status of a virtual machine.

Parameters:	compute_id – virtual machine UUID
Returns:	constant of amphora status

validate_flavor(flavor_id)[source]¶

Validates that a flavor exists in nova.

Parameters:	flavor_id – ID of the flavor to lookup in nova.
Raises:	NotFound
Returns:	None
