Fission Serverless Plugin

Note: This plugin is out of maintainance, may not work out of box. Happy to receive contributions.

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 -g

Try out the example

Clone repo and check the example function

$ git clone https://github.com/fission/serverless-fission/
$ cd examples/python
$ cat serverless.yml
service: hello

provider:
  name: fission
  runtime: python2.7

plugins:
  - serverless-fission

functions:
  hello:
    description: 'Hello function'
    handler: handler.hello

Download 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 created

The function will be deployed to Kubernetes via fission.

$ fission function list
NAME  UID                                  ENV    EXECUTORTYPE MINSCALE MAXSCALE MINCPU MAXCPU MINMEMORY MAXMEMORY TARGETCPU

$ kubectl get pods --all-namespaces
NAMESPACE          NAME                                                              READY     STATUS        RESTARTS   AGE

fission-function   python-2b073331-7459-11e8-a089-080027cdd0a9-5h3iitxq-66b4c5vzpv   2/2       Running       0          15s

Now you will be able to call the function:

$ serverless invoke --router 127.0.0.1 --port 8443 --fnname hello
hello world

If you are using minikube, you can call the function through HTTP and the Node Port in which function is running:

$ curl  http://$(minikube ip):31314/hello
hello world

If 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
Fission environment 'python' deleted
