F2S OSS is our OpenSource Functions as a Service Platform for Kubernetes.
It is under active development and has a lot of useful business features:

• scale to zero
• autoscaling
• gitops configuration (crd's)
• kafka integration (in development)
• authentication (none, basic, token)

Architecture

F2S uses 2 namespaces: "F2S" - where the F2S Operator runs and "F2S-Containers", where the workloads / Pods are started.

The F2S Operator itself is an opensource Go-Program. One instance of the F2S Operator will serve as the master. F2S Operator encompasses the following components:

• API Server
  API Server is the REST API Interface. Functions can be defined and invoked via API. All invocations are sent to the dispatcher component.
• Metrics
  F2S Exposes Metrics in order to be able to make scaling decisions and have insight in all current activity
• Config
  The Config Component observes CRD's (F2SFunction Declarations) in "f2s" namespace on Kubernetes
• Kafka
  Package for Interaction with Kafka Event Bus (planned). All invocations are sent to dispatcher.
• Operator
  Operator reacts to Config Changes and creates or deletes deployments and services in f2s-containers namespace. It is also responsible for scaling functions up and down.
• Dispatcher
  Dispatcher picks up all incoming requests (REST, Kafka) and decides which function pod should serve the request.

Gitops

F2S allows for a Gitops approach as you can define all F2S Function Declarations by Kubernetes CRDs
