OpenFaaS (Functions as a Service) is a framework for building serverless functions with Docker and Kubernetes which has first class support for metrics. Any process can be packaged as a function enabling you to consume a range of web events without repetitive boiler-plate coding.

OpenFaaS is a framework for building serverless functions on the top of containers through the use of Docker and Kubernetes. With OpenFaaS, serverless functions can be managed anywhere with the same unified experience. This includes on the user's laptop, on-premises hardware, or by creating a cluster in the cloud.

You can find Function templates for various programming languages in their templates GitHub repository.
