Build strategy that is Dockerfile (for simple use cases)

[aslom]

That was mentioned during today WG call.

If I understand it correctly that would be simpler build strategy when buildpacks or s2i is not needed? @lance

I think a reasonable option would be to add a docker package here: https://github.com/knative/func/tree/main/pkg/builders and when specified in func.yaml or on the command line as func build --builder=docker the CLI looks for a Dockerfile and builds using the docker/podman APIs. @matejvasek wdyt?

[zroubalik]

Are we going to provide Dockerfiles with the language templates or do we keep it on users?

[lance]

Good question! We could start with templates in knative-sandbox/func-tastic, perhaps?
