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

Quick Start

A Vagrant machine is the easiest way to run OpenWhisk on Mac, Windows PC or GNU/Linux. Download and install VirtualBox and Vagrant for your operating system and architecture.

Note: For Windows, you may need to install an ssh client in order to use the command vagrant ssh. Cygwin works well for this, and Git Bash comes with an ssh client you can point to. If you run the command and no ssh is installed, Vagrant will give you some options to try.

Follow these step to run your first OpenWhisk Action:

# Clone openwhisk
git clone --depth=1 openwhisk

# Change directory to tools/vagrant
cd openwhisk/tools/vagrant

# Run script to create vm and run hello action

Wait for hello action output:

wsk action invoke /whisk.system/utils/echo -p message hello --result
    "message": "hello"

These steps were tested on Mac OS X El Capitan, Ubuntu 14.04.3 LTS and Windows using Vagrant. For more information about using OpenWhisk on Vagrant see the tools/vagrant/

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.
