OpenLambda is an Apache-licensed serverless computing project, written in Go and based on Linux containers. One of the goals 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
These instructions assume you are the root user.
Install Docker and the Go compiler, then build OpenLambda:
make
Now you can use the admin tool to create a local OpenLamda cluster:
./bin/admin new -cluster my-cluster
Now start a single local worker process in your cluster:
./bin/admin workers -cluster=my-cluster
Confirm that the worker is listening and responding to requests:
./bin/admin status -cluster=my-cluster
You should see something like the following:
Worker Pings:
http://localhost:8080/status => ready [200 OK]
Cluster containers:
The default configuration uses a local directory to store handler code, so creating new Lambda functions is as simple as writing files in the ./my-cluster/registry.
Copy an example handler to this directory:
cp -r ./quickstart/handlers/hello ./my-cluster/registry/hello
AJAX is an RPC protocol often used by web applications to communicate with backend services. AJAX issues calls via HTTP, and marshalls arguments using JSON. Thus, we can issue an AJAX call from the command line, via curl:
curl -X POST localhost:8080/runLambda/hello -d '{"name": "Alice"}'
The request should return the following:
"Hello, Alice!"
To create your own Lambda function named <NAME>, write your code to
./my-cluster/registry/<NAME>/lambda_func.py, then invoke it via curl:
curl -X POST localhost:8080/runLambda/<NAME> -d '<JSON>'
The <JSON> string will be parsed to a Python object and passed to
the handler function via the event argument.
To run the unit tests:
make test
