Ramdisk Deploy Interface

class ironic.drivers.modules.ramdisk.RamdiskDeploy(*args, **kwargs)

Bases: AgentBaseMixin, HeartbeatMixin, DeployInterface

deploy(task)

Perform a deployment to the task’s node.

Perform the necessary work to deploy an image onto the specified node. This method will be called after prepare(), which may have already performed any preparatory steps, such as pre-caching some data for the node.

Parameters:

task – A TaskManager instance containing the node to act on.

Returns:

status of the deploy. One of ironic.common.states.

get_properties()

Return the properties of the interface.

Returns:

dictionary of <property name>:<property description> entries.

prepare(task)

Prepare the deployment environment for the task’s node.

If preparation of the deployment environment ahead of time is possible, this method should be implemented by the driver.

If implemented, this method must be idempotent. It may be called multiple times for the same node on the same conductor.

This method is called before deploy.

Parameters:

task – A TaskManager instance containing the node to act on.

validate(task)

Validate the driver-specific Node deployment info.

This method validates whether the ‘driver_info’ and/or ‘instance_info’ properties of the task’s node contains the required information for this interface to function.

This method is often executed synchronously in API requests, so it should not conduct long-running checks.

Parameters:

task – A TaskManager instance containing the node to act on.

Raises:

InvalidParameterValue on malformed parameter(s)

Raises:

MissingParameterValue on missing parameter(s)
