This plugin brings Fission support within the Serverless Framework.
Pre requisites
Make sure you have a fission running and fission-cli is installed. You can find the installation intructions here.
You can install serverless with npm,
$ npm install serverless -gTry out the example
Clone repo and check the example function

runtime: python2.7
plugins:
- serverless-fission
functions:
hello:
description: 'Hello function'
handler: handler.helloDownload dependencies
$ npm install ../../Create an Environment.
$ serverless create --template node-1 --img node --nmspace default
Fission environment node-1 created. Deploy function.
$ serverless deploy --template hello --env node-1 --code hello.js
Fission function hello createdThe function will be deployed to Kubernetes via fission.
$ fission function list
NAME UID ENV EXECUTORTYPE MINSCALE MAXSCALE MINCPU MAXCPU MINMEMORY MAXMEMORY TARGETCPU

hello worldIf you want to remove the deployed function.
$ serverless remove --fn hello --nmspace default
Fission function hello deleted.If you wanted to rollback one of the created environments.
$ serverless rollback --env node-1 --nmspace
