Serverless

FaaS

Actually Servers?

Events

Containers?

Serverless

What is Knative (knative.dev and github.com/knative )
- A framework built on top of Kubernetes and Istio to build, trigger, and run Serverless functions
What is in Knative
- A collection of CRDs and Controllers
  - Serving: Route requests; auto scale; invoke serverless functions.
  - Eventing: Receive, persist, filter, and deliver Event
  - Build: steps to build from source to image
Who are developing Knative
- Led by Google, joined by Red Hat, IBM, Pivotal...

Knative

Also BuilDs

CI/CD

Don't we have enough of those?

Containers

Source

Knative/build

Templated API resource to take an input (like a git repo URL) and produce a container to serve
Narrowly focused on serverless use-case
A number of templates available, including s2i images and Dockerfile with buildah
something almost, but not quite entirely unlike CD

TEKTON

Also a container build resources, but allows for much broader than only serverless
Split from Knative into its own org (also now a part of https://cd.foundation/ )
Expected to underpin the basics needed by knative/build
Very analogous to our BuildStrategy and Pipelines in OpenShift
