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.
