OpenFaaS是一个让开发者能够将任何Docker镜像转化为无服务器功能的平台。通过加入Function Watchdog，可以接收HTTP请求并将其转发到目标进程的标准输入。响应则通过标准输出返回给调用者。该平台内置了API网关，可以提供外部路由访问功能，并收集通过Prometheus的云原生指标。API网关可以根据需求调整Docker Swarm或Kubernetes API中的服务副本数量来扩展功能。

Overview of OpenFaaS

Function Watchdog

- You can make any Docker image into a serverless function by adding the Function Watchdog (a tiny Golang HTTP server)
- The Function Watchdog is the entrypoint allowing HTTP requests to be forwarded to the target process via STDIN. The response is sent back to the caller by writing to STDOUT from your application.
- API Gateway / UI Portal
  - The API Gateway provides an external route into your functions and collects Cloud Native metrics through Prometheus.
  - Your API Gateway will scale functions according to demand by altering the service replica count in the Docker Swarm or Kubernetes API.
  - A UI is baked in allowing you to invoke functions in your browser and create new ones as needed.
