http: HTTP Trigger

The HTTP trigger is the only trigger created by default if not configured (by default, it has 1 worker). This trigger handles incoming HTTP requests at container port 8080, assigning workers to incoming requests. If a worker is not available, a 503 error is returned.

Attributes

Path	Type	Description
port	int	The NodePort (or equivalent) on which the function will serve HTTP requests. If empty, chooses a random port within the platform range.
ingresses.(name).host	string	The host to which the ingress maps.
ingresses.(name).paths	list of strings	The paths that the ingress handles. Variables of the form {{.<NAME>}} can be specified using .Name, .Namespace, and .Version. For example, /{{.Namespace}}-{{.Name}}/{{.Version}} will result in a default ingress of /namespace-name/version.
