Apache OpenWhisk is an open source serverless cloud platform

OpenWhisk

OpenWhisk is a cloud-first distributed event-based programming service. It provides a programming model to upload event handlers to a cloud service, and register the handlers to respond to various events. Learn more at http://openwhisk.apache.org.

Quick Start

The easiest way to start using OpenWhisk is to get Docker installed on Mac, Windows or Linux. The Docker website has detailed instructions on getting the tools installed. This does not give you a production deployment but gives you enough of the pieces to start writing functions and seeing them run.

git clone https://github.com/apache/openwhisk-devtools.git
cd openwhisk-devtools/docker-compose
make quick-start

For more detailed instructions or if you encounter problems see the OpenWhisk-dev tools project.

Kubernetes Setup

Another path to quickly starting to use OpenWhisk is to install it on a Kubernetes cluster. On a Mac, you can use the Kubernetes support built into Docker 18.06 (or higher). You can also deploy OpenWhisk on Minikube, on a managed Kubernetes cluster provisioned from a public cloud provider, or on a Kubernetes cluster you manage yourself. To get started,

git clone https://github.com/apache/openwhisk-deploy-kube.git

Then follow the instructions in the OpenWhisk on Kubernetes README.md.

Native development

Docker must be natively installed in order to build and deploy OpenWhisk. If you plan to make contributions to OpenWhisk, we recommend either a Mac or Ubuntu environment.

• Setup Mac for OpenWhisk
• Setup Ubuntu for OpenWhisk
