Volume

Volumes are network attached storage such as the EBS service within Amazon Web Services. This class inherits from TopLevelResource and has direct access to the resource’s database object.

Attribute	Description
resource_id	The provider ID of the volume
organization_service_id	The ID of the parent organization service (cloud)
region_name	The region that the volume resides in
volume_id	The provider ID of the volume
name	The name of the volume
instance_resource_id	The resource ID of the instance this volume is associated with
snapshot_resource_id	The resource ID of the snapshot this volume was built from
create_time	Timestamp of when this volume was created
device	The device that a volume is mapped to on the instance (e.g., /dev/sdf)
state	The current state of the volume (available or in-use)
volume_type	The type of volume (e.g., pd-standard, gp2, premium_LRS, etc.)
size	The size in gigabytes of the volume
availability_zone	The availability_zone where the volume resides
iops	The total IOPS allocated to this volume (provisioned volumes only)
encrypted	Denotes whether the volume is encrypted
delete_on_termination	Whether or not the volume is set to automatically delete when the parent instance is terminated
snapshots	Returns a list of associated snapshots of this volume

Volume Operations

delete(user_resource_id=None)

Delete this resource. If wrapped in a with JobQueue() block, this will queue the deletion job to the wrapped queue, otherwise it calls immediately.

get_attached_instance_resource_id()

Retrieve the resource id of the instance this volume is attached to, if any.

get_availability_zone()

Retrieve the availability zone/location of the resource.

get_date_created()

Retrieve the time from the provider that this resource was created (if available).

static get_db_class()

get_device()

Retrieve the attached device name of the volume (e.g., /dev/sdf).

get_parent_resource_id()

static get_provider_id_field()

static get_resource_type()

get_size()

Retrieve the size in GB of the resource.

get_snapshots()

Retrieve a list of db objects for snapshots created from the volume (if any)

get_supported_actions()

Retrieve all the actions which are supported by this resource.

get_volume_backup_scheduled_events()

Retrieve volume backup scheduled events.

get_volume_type()

Retrieve the volume type of the resource.

handle_resource_created(user_resource_id=None, project_resource_id=None)

This should be called when a resource is created/discovered after the basic data is added to the database. This gives an opportunity for post-addition hooks (assignment to projects/groups, alerts, etc).

handle_resource_destroyed(user_resource_id=None)

This should be called when a resource is destroyed before the basic data is removed from the database. This gives an opportunity for pre-destruction hooks (removal from projects/groups, alerts, etc).

handle_resource_modified(resource, *args, **kwargs)

This should be called when a resource is modified after the new data has been updated in the DB session. This gives an opportunity for post-modification hooks.

modify(iops=None, size=None, volume_type=None, user_resource_id=None)

Modify the volume. This makes a call sot he upstream providier to change one or more properties.

schedule_modification(*args, **kwargs)

Create a scheduled event to modify an existing volume. If a schedule is not supplied then the event will be scheduled to run immediately.
