Fission

Fission is a fast serverless framework for Kubernetes with a focus on developer productivity and high performance.

It's customizable (with sensible defaults), extensible to any language, and interoperates well with other infrastructure.

See https://fission.io for more.

Running Fission

On your own Kubernetes cluster

Setup Kubernetes

On your laptop:

https://github.com/kubernetes/minikube

Or use Google Container Engine.

Verify access to the cluster

$ kubectl version

Get and Run Fission

If you're using GKE, use the fission.yaml unmodified. If you're using minikube, change all instances of LoadBalancer services to NodePort.

$ curl http://fission.io/fission.yaml | kubectl create -f -

$ kubectl --namespace fission get services

Save the external IP addresses of controller and router services in FISSION_URL and FISSION_ROUTER, respectively.

Install the client CLI

$ curl http://fission.io/fission > fission

$ chmod +x fission

$ sudo mv fission /usr/local/bin/

Run an example

$ fission env create --name nodejs --image fission/node-env

$ echo 'module.exports = function(context, callback) { callback(200, "Hello, world!\n"); }' > hello.js

$ fission function create --name hello --env nodejs --code hello.js

$ fission route create --method GET --url /hello --function hello

$ curl http://$FISSION_ROUTER/hello Hello, world!

Status

Fission is in early alpha. Watch this space for announcements soon!

Performance

The alpha release has focussed on cold-start latency performance. For requests that don't have a running instance, i.e. a "cold start", fission has a latency overhead of less than 100 msec for the NodeJS environment.
