runway.cfngin.lookups.handlers.rxref module

Handler for fetching outputs from a stack in the current namespace.

class runway.cfngin.lookups.handlers.rxref.RxrefLookup

Bases: runway.lookups.handlers.base.LookupHandler

Rxref lookup.

classmethod handle(value, context=None, provider=None, **kwargs)

Fetch an output from the designated stack in the current namespace.

The output lookup supports fetching outputs from stacks created within a single config file. Sometimes it’s useful to fetch outputs from stacks created outside of the current config file but using the same namespace. rxref supports this by using the runway.cfngin.context.Context to expand the fqn of the stack.

Parameters

• value (str) – Parameter(s) given to this lookup. <stack_name>::<output_name>

• context (runway.cfngin.context.Context) – Context instance.

• provider (runway.cfngin.providers.base.BaseProvider) – Provider instance.

Returns

Output from the specified stack.

Return type

str

Example

conf_value: ${rxref relative-stack-name::SomeOutputName}
