Instantiate class.

Parameters

name – A name for the blueprint.
context – Context the blueprint is being executed under.

Deprecated since version 2.0.0: Replaced by required_parameter_definitions.

Returns: Dict of required CloudFormation Parameters for the blueprint. Will be a dictionary of <parameter name>: <parameter attributes>.

get_variables() → Dict[str, Any]

Return a dictionary of variables available to the template.

These variables will have been defined within VARIABLES or self.defined_variables. Any variable value that contains a lookup will have been resolved.

Deprecated since version 2.0.0: Replaced by variables.

Returns: Variables available to the template.
Raises: UnresolvedBlueprintVariables – If variables are unresolved.

import_mappings() → None: Import mappings from CFNgin config to the blueprint.
