OpenWhisk is a serverless functions platform for building cloud applications. OpenWhisk offers a rich programming model for creating serverless APIs from functions, composing functions into serverless workflows, and connecting events to functions using rules and triggers. Learn more at http://openwhisk.apache.org.

The easiest way to start using OpenWhisk is to install the "Standalone" OpenWhisk stack. This is a full-featured OpenWhisk stack running as a Java process for convenience. Serverless functions run within Docker containers. You will need Docker, Java and Node.js available on your machine.
To get started:
git clone https://github.com/apache/openwhisk.git cd openwhisk ./gradlew core:standalone:bootRun
When the OpenWhisk stack is up, it will open your browser to a functions [Playground](./docs/images/playground-ui.png), typically served from http://localhost:3232. The Playground allows you create and run functions directly from your browser.
To make use of all OpenWhisk features, you will need the OpenWhisk command line tool called
wskwhich you can download from https://s.apache.org/openwhisk-cli-download. Please refer to the [CLI configuration](./docs/cli.md) for additional details. Typically you configure the CLI for Standalone OpenWhisk as follows:
wsk property set \ --apihost 'http://localhost:3233' \ --auth '23bc46b1-71f6-4ed5-8c54-816aa4f8c502:123zO3xZCLrMN6v2BKK1dXYFpXlPkccOFqm12CdAsMgRU4VrNZ9lyGVCGuMDGIwP'
Standalone OpenWhisk can be configured to deploy additional capabilities when that is desirable. Additional resources are available [here](./core/standalone/README.md).
Deploy to Kubernetes
OpenWhisk can also be installed on a Kubernetes cluster. You can use a managed Kubernetes cluster provisioned from a public cloud provider (e.g., AKS, EKS, IKS, GKE), or a cluster you manage yourself. Additionally for local development, OpenWhisk is compatible with Minikube, and Kubernetes for Mac using the support built into Docker 18.06 (or higher).
To get started:
git clone https://github.com/apache/openwhisk-deploy-kube.git
Then follow the instructions in the OpenWhisk on Kubernetes README.md.

Project Repository Structure
The OpenWhisk system is built from a [number of components](docs/dev/modules.md). The picture below groups the components by their GitHub repos. Please open issues for a component against the appropriate repo (if in doubt just open against the main openwhisk repo).
