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_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
