# Refunc
Refunc is a [Kubernetes](https://kubernetes.io) native serverless platform.
## Features
* Easy of use - Embrace the serverless ecosystem with an AWS Lambda compatible API and runtimes
* Portable - Run everywhere that has Kubernetes
* Scale from zero - Autoscale from zero-to-many and vice versa
* Extensible - Runtime compatibility layer (lambda and other clouds' function), transport layer ([NATS](https://nats.io) based for now)
## Quick Start
Before starting, you need a Kubernetes cluster. You can use [minikube](https://github.com/kubernetes/minikube) to run a minimal Kubernetes cluster locally.
If you'd like to run on macOS, [Docker for Mac](https://docs.docker.com/docker-for-mac/kubernetes/) with Kubernetes enabled is recommended.
### Install Refunc
Install `refunc-play`, a minimal setup of Refunc, using the following commands:
```shell
# This will create namespace `refunc-play` and deploy components in it
docker run --rm -it refunc/refunc refunc play gen -n refunc-play | kubectl apply -f -
# create runtime python3.7
kubectl create -n refunc-play -f \
https://github.com/refunc/lambda-python3.7-example/releases/download/v0.0.2/xenv.yaml
```
Here we use the python3.7 runtime as an example. Currently Refunc supports all [AWS provided runtimes](https://docs.aws.amazon.com/lambda/latest/dg/runtimes-custom.html) as well as some converted runtimes, check [refunc/lambda-runtimes](https://github.com/refunc/lambda-runtimes) to learn more.
### The AWS Way
Refunc uses an AWS API compatible [gateway](https://github.com/refunc/aws-api-gw) to provide Lambda and S3 services,
which makes it possible to use the AWS CLI to manage functions locally.
Before starting, we need to forward the gateway to your localhost:
```shell
kubectl port-forward deployment/aws-api-gw 9000:80 -n refunc-play
```
Download the pre-built [function](https://github.com/refunc/lambda-python3.7-example) for convenience:
```shell
cd /tmp
wget https://github.com/refunc/lambda-python3.7-example/releases/download/v0.0.1/lambda.zip
```
#### Create Function
```shell
aws --endpoint-url=http://127.0.0.1:9000 \
lambda create-function --function-name localtest \
--handler lambda_function.lambda_handler \
--zip-file fileb:///tmp/lambda.zip \
--runtime python3.7 \
--role arn:aws:iam::XXXXXXXXXXXXX:role/your_lambda_execution_role
```
#### Invoke Function
```shell
aws --endpoint-url=http://127.0.0.1:9000 \
lambda invoke --function-name localtest /tmp/output.json && cat /tmp/output.json
```
### The Refunc Way
Let's create a Lambda function using the python3.7 runtime with an HTTP endpoint:
```shell
kubectl create -n refunc-play -f https://github.com/refunc/lambda-python3.7-example/releases/download/v0.0.2/inone.yaml
```
Forward the Refunc HTTP gateway to your localhost:
```shell
kubectl port-forward deployment/refunc-play 7788:7788 -n refunc-play
```
Now, it's OK to send a request to your function:
```shell
curl -v http://127.0.0.1:7788/refunc-play/python37-function
```
## User Interface
Internally we use [Rancher](https://rancher.com) to build our PaaS and other internal services. Currently there is a simple management [UI](https://github.com/refunc/refunc-ui) forked from [rancher/ui](https://github.com/rancher/ui) which is backed by our [Rancher API](https://github.com/rancher/api-spec) compatible [server](https://github.com/refunc/refunc-rancher).
