OpenLambda is an Apache-licensed serverless computing project, written in Go and based on Linux containers. The primary goal of OpenLambda is to enable exploration of new approaches to serverless computing. Our research agenda is described in more detail in a HotCloud '16 paper.

Getting Started

OpenLambda relies heavily on operations that require root privilege. To simplify this, we suggest that you run all commands as the root user. OpenLambda is only actively tested on Ubuntu 16.04 LTS.

Build and Test

OL is changing rapidly. We recommend syncing to a commit that passed our nightly tests:

Our tests run on a VM built with this init script: Thus, you can consider that file testable documentation of the dependencies.

You can build the ol and other resources with just make. Then make sure it works with some simple tests:

make test-all

Getting Started

You can create a new OL environment with the following comment:

./ol new

This creates a directory named default with various OL resources. You can create an OL environment at another location by passing a -path=DIRNAME to the new command.

Default config settings were saved to ./default/config.json. Modify them if you wish, then start an OL worker (if you used -path above, use it again with the worker command):

./ol worker

In another terminal, make sure the worker is running with ./ol status.

Now save the following to ./default/registry/

def f(event):
    return event

Now invoke your lambda (the result should be the same as the POST body):

curl -X POST localhost:5000/run/echo -d '{"hello": "world"}'

When you're done, just kill the worker with ctrl-C. If you want to run the worker in detached mode (i.e., in the background), just start it again with the -d flag:

./ol worker -d

You can shutdown a detached worker like this:

./ol kill
