openfaas

Description
Deploy a OpenFaaS function using Garden. Requires the openfaas provider to be configured.
Below is the full schema reference. For an introduction to configuring Garden modules, please look at our Configuration guide.
The first section contains the complete YAML schema, and the second section describes each schema key.
openfaas modules also export values that are available in template strings. See the Outputs section below for details.

# Disabling a module means that any services, tasks and tests contained in it will not be deployed or run. It also
# means that the module is not built _unless_ it is declared as a build dependency by another enabled module (in which
# case building this module is necessary for the dependant to be built).
#
# If you disable the module, and its services, tasks or tests are referenced as _runtime_ dependencies, Garden will
# automatically ignore those dependency declarations. Note however that template strings referencing the module's
# service or task outputs (i.e. runtime outputs) will fail to resolve when the module is disabled, so you need to make
# sure to provide alternate values for those if you're using them, using conditional expressions.
