### [Read this on the main serverless docs site](https://www.serverless.com/framework/docs/providers/kubeless/guide/functions) # Kubeless - Functions If you are using Kubeless as a provider, all *functions* inside the service are Kubernetes Function.v1.k8s.io objects. ## Configuration All of the Kubeless Functions in your serverless service can be found in `serverless.yml` under the `functions` property. ```yml # serverless.yml service: my-service provider: name: kubeless runtime: python2.7 plugins: - serverless-kubeless functions: # The top name will be the name of the Function object # and the K8s service object to get a request to call the function hello: # The function to call as a response to the HTTP event handler: handler.hello ``` The `handler` property points to the file and module containing the code you want to run in your function. ```python // handler.py import json def hello(request): body = { "message": "Go Serverless v1.0! Your function executed successfully!", "input": request.json } response = { "statusCode": 200, "body": json.dumps(body) } return response ``` You can add as many functions as you want within this property. ```yml # serverless.yml service: my-service provider: name: kubeless runtime: python2.7 plugins: - serverless-kubeless functions: hello_one: handler: handler.hello_one hello_two: handler: handler.hello_two ``` ## Runtimes The Kubeless provider plugin supports the following runtimes. - Node.js - Python - Ruby Please see the following repository for sample projects using those runtimes: [https://github.com/serverless/serverless-kubeless/tree/master/examples](https://github.com/serverless/serverless-kubeless/tree/master/examples)
