OCI Fn Function as Serverless Service

The Fn project is an open-source container-native serverless platform that you can run anywhere any cloud or on-premise.
It’s easy to use, supports every programming language, and is extensible and performant.

If you are new to fn function, then start with fn init command which creates a function boilerplate (Starting point). Sample python code is generated wiht a handler function with ctx and data variables. ctx is the function input variables and the data is the event input variable in json format. It also generates a func.yaml file used to create Dockerfile for code deployment and a requirements.txt to add the dependency python modules in it.

$ fn init --runtime python pythonfn
$ cd pythonfn
$ ls
func.py func.yaml requirements.txt
$ cat func.py

import json  
from fdk import response  
def handler(ctx, data: io.BytesIO=None):  
   name = "World"  
   try:  
       body = json.loads(data.getvalue())  
       name = body.get("name")  
   except (Exception, ValueError) as ex:  
       print(str(ex))  
   return response.Response(  
       ctx, response_data=json.dumps(  
           {"message": "Hello {0}".format(name)}),  
       headers={"Content-Type": "application/json"}  
   )  

$ cat func.yaml
